And when the picture information is matched in the mapping relation according to the picture information, matching the picture information with the key frame information, taking the key frame corresponding to the key frame information obtained by matching as a target key frame, and then determining the target video according to the target key frame. Different videos may include the same key-frame, for example, in a television episode, each episode including the same slice header portion, so that one key-frame may correspond to multiple videos.
And step 103, sending the information of the target video to the client.
And sending the obtained information of the target video to the client to recommend the video matched with the picture information for the user. The information of the target video comprises an access address of the target video, the client can acquire the target video through the access address, for example, a user can watch the target video on the client by clicking the access address, the user does not need to manually search the video according to the picture information at the moment, the video acquisition efficiency is high, and the user experience is improved. In addition, the information of the target video may also include a brief description of the target video, which facilitates the user to learn more information.
In the embodiment, picture information is acquired; determining a target key frame matched with the picture information in a mapping relation obtained in advance, and obtaining a target video comprising the target key frame; wherein the mapping relationship comprises a corresponding relationship between the target key frame and the target video; and sending the information of the target video to a client. Therefore, the server sends the target video matched with the picture information to the client to recommend the video matched with the picture information for the user, so that the time for the user to manually search the video according to the picture information is saved, and the video acquisition efficiency is improved.
Referring to fig. 2, fig. 2 is a second flowchart of a video recommendation method according to an embodiment of the present invention, and as shown in fig. 2, the video recommendation method according to the embodiment is applied to a server, and includes the following steps:
The picture information is information that can be used to characterize a picture, for example, texture information of the picture, color information of the picture, and the like. In this step, the server may obtain the picture information through the client, that is, receive the picture information sent by the client, or obtain the picture information of the picture in the page when the server sends the page content to the client, which is not limited herein. The page may be a web page.
In this step, the server obtains one or more pieces of picture information, that is, obtains the picture information of one or more pictures. Each picture corresponds to one picture information.
Step 202-step 203 are one implementation of step 102. In this step, when one piece of picture information is acquired, matching is performed in a mapping relation according to the one piece of picture information to match a key frame matched with the one piece of picture information, and finally a video set is acquired according to the matched key frame.
When the plurality of pieces of picture information are acquired, key frames are acquired according to the picture information in the plurality of pieces of picture information respectively, and videos corresponding to the key frames are determined according to the key frames. The video set includes all videos acquired from the key frames.
And selecting N videos from the video set as target videos, wherein N is a positive integer. When determining the target video, the following method can be adopted for determination:
under the condition that the picture information is acquired, the historical accumulation times of the target video which is retrieved are higher than the historical accumulation times of other videos which are detected; wherein the other videos are videos in the video set except the target video.
Specifically, when one piece of picture information is acquired, a video set is acquired according to the one piece of picture information, and a video with a high historical accumulation frequency detected in the video set is determined as a target video. For example, if the one piece of picture information is picture information a, the videos determined according to the picture information a are video 1 and video 2, the historical retrieval frequency (i.e., the historical accumulation frequency) of the video 1 is 2 ten thousand, the historical retrieval frequency (i.e., the historical accumulation frequency) of the video 2 is 3 ten thousand, the historical accumulation frequency of the video 2 being retrieved is greater than the historical accumulation frequency of the video 3 being retrieved, and the video 2 is more likely to be a video meeting the user's requirements, so that the video 2 is recommended to the user as the target video, and the recommendation accuracy can be improved.
In the case of acquiring the plurality of pieces of picture information, the target video may be determined as follows:
the target video is retrieved more times in the video set than other videos are detected;
or the display position of the picture information corresponding to the target video in the page is positioned before the display positions of the pictures of the picture information corresponding to other videos in the page;
or the similarity between the text information corresponding to the target video and the text information in the key frame of the target video is higher than the similarity between the text information corresponding to other videos and the text information in the key frames of the other videos, wherein the text information corresponding to the target video is the text in the preset distance of the picture position of the picture information corresponding to the target video in the page;
wherein the other videos are videos in the video set except the target video.
Specifically, when a plurality of pieces of picture information are acquired, the same video may be acquired according to different pieces of picture information, and at this time, the video may appear in a video set many times. For example, if the plurality of picture information includes picture information a and picture information B, the videos determined from the picture information a are video 1 and video 2, and the videos determined from the picture information B are video 1 and video 3, then the video 1 is retrieved 2 times and the videos 2 and 3 are retrieved 1 time in the video set, that is, the video 1 is retrieved more times than the other videos (video 2 and video 3) in the video set, and then the video 1 can be determined as the target video.
Under the condition that the picture represented by the picture information is a picture in the page, the video determined according to the picture information of the picture can be screened according to the display position of the picture in the page, so that the display position of the picture information corresponding to the target video in the page is positioned before the display positions of the pictures of the picture information corresponding to other videos in the page. For example, the page includes a picture a and a picture B, the display position of the picture a in the page is located before the picture B, the picture a corresponds to the picture information a, the picture B corresponds to the picture information B, the video determined according to the picture information a is a video 1, and the video determined according to the picture information B is a video 2. Since the display position of picture a in the page is before picture B, video 1 may be determined as the target video.
When the target video is determined, the filtering can be performed by combining the characters of the pictures around the display position of the page. And comparing the text information of the picture within a preset distance from the display position of the page with the text information in the key frame of each video in the video set to determine the similarity. And determining the video corresponding to the key frame where the text information with high similarity is located as the target video, namely, the similarity between the text information corresponding to the target video and the text information in the key frame of the target video is higher than the similarity between the text information corresponding to other videos and the text information in the key frames of the other videos.
The text information corresponding to the target video is the text of the distance between the picture positions of the picture information corresponding to the target video in the page and the preset distance; and the text information corresponding to the other videos is the text in the preset distance of the picture position of the picture information corresponding to the other videos in the page. The picture position is the display position of the picture in the page. The preset distance may be set according to actual conditions, and is not limited herein. For example, the page includes a picture a, a text description "the spring and evening list is disclosed greatly" exists within a preset distance of a display position of the picture a, videos determined according to picture information of the picture a are a video 1 and a video 2, text information in a key frame of the video 1 is "the spring and evening list disclosed", and text information in a key frame of the video 2 is "the spring and evening". Because the similarity between the text information "spring and late list public" and "spring and late list public" is higher than the similarity between "spring and late list public", the video corresponding to the key frame including "spring and late list public" is determined as the target video, that is, the video 1 is determined as the target video.
In this embodiment, the target video is determined in the three ways, and the video with the concentrated video can be screened by adopting different screening bases, so that more accurate video recommendation is provided for the user, the user experience is further improved, and the user viscosity is increased.
Further, in addition to the above-described determination of the target video based on the number of times the video is retrieved, the display position of the picture on the web page, and the similarity between the text information near the display position of the picture and the key frame, the target video may be determined by combining the number of times the video is retrieved, the display position of the picture on the web page, and the similarity between the text information near the display position of the picture and the key frame.
Determining N videos in the video set as the target video, including:
setting weights for videos in the video set; and sequencing the videos from large to small according to the weight, and determining N videos sequenced at the top as target videos.
For example, if the plurality of picture information includes picture information a and picture information B, the video determined from the picture information a is video 1 and video 2, and the video determined from the picture information B is video 1 and video 3, then in the video set, the video 1 is retrieved 2 times, the video 2 and video 3 are retrieved 1 time, and the weight of the video 1 is greater than that of the video 2 and video 3.
The closer the display position of the picture corresponding to the picture information in the page is, the larger the weight of the video determined according to the picture information is. For example, the page includes a picture a and a picture B, the display position of the picture a in the page is located before the picture B, the picture a corresponds to the picture information a, the picture B corresponds to the picture information B, the video determined according to the picture information a is a video 1, and the video determined according to the picture information B is a video 2. Since the display position of picture a in the page is before picture B, the weight set for video 1 is greater than the weight for video 2.
When setting the weight for the video according to the similarity of the text information, the method comprises the following steps:
determining text information in the page within a preset distance of the display position of the picture;
carrying out similarity matching on the character information and the character information in the first key frame; the first key frame is one of key frames matched with each piece of picture information in the plurality of pieces of picture information;
and setting weights for the videos in the video set, wherein the higher the similarity is, the higher the weight of the video corresponding to the first key frame is.
For example, the page includes a picture a, a text description "the spring and evening list is disclosed greatly" exists within a preset distance of a display position of the picture a, videos determined according to picture information of the picture a are a video 1 and a video 2, text information in a key frame of the video 1 is "the spring and evening list disclosed", and text information in a key frame of the video 2 is "the spring and evening". The similarity between the text information "the publication of the spring and evening list" and "the publication of the spring and evening list" is higher than the similarity between the text information "the publication of the spring and evening list" and "the publication of the spring and evening list", and the weight set for the video 1 is higher than the weight for the video 2.
By setting the weight for the video in the video set, the number of times that the video is retrieved, the display position of the picture in the webpage, the character information near the display position of the picture and the similarity of the key frame can be combined, so that the video in the video set is screened by adopting a more comprehensive screening basis, and the determined target video is more accurate.
And step 204, sending the information of the target video to a client.
And sending the obtained information of the target video to the client to recommend the video matched with the picture information for the user. The information of the target video comprises an access address of the target video, the client can acquire the target video through the access address, for example, a user can watch the target video on the client by clicking the access address, the user does not need to manually search the video according to the picture information at the moment, the video acquisition efficiency is high, and the user experience is improved. In addition, the information of the target video may also include a brief description of the target video, which facilitates the user to learn more information.
In the embodiment, a plurality of pieces of picture information are acquired; determining a key frame matched with each piece of picture information in the plurality of pieces of picture information in the mapping relation to obtain a video corresponding to the determined key frame to obtain a video set; determining N videos in the video set as the target video, wherein N is a positive integer; and sending the information of the target video to a client. Therefore, after the server acquires the video matched with the picture information, the video is screened to recommend a more accurate video for the user, so that the time for the user to manually search the video according to the picture information is saved, and the video acquisition efficiency is improved.
Referring to fig. 3, fig. 3 is a third flowchart of a video recommendation method according to an embodiment of the present invention, and as shown in fig. 3, the video recommendation method according to the embodiment is applied to a client, and includes the following steps:
The picture information is information that can be used to characterize a picture, for example, texture information of the picture, color information of the picture, and the like. The picture represented by the picture information may be a picture in a page. When the picture information is sent to the server, the picture information can be actively sent to the server through the client for the user, or the picture information in the page content can be automatically obtained by the client after the page content is obtained by the client, and the picture information is sent to the server. The page may be a web page.
The client may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
The information related to the mapping relationship may specifically refer to the record in step 102, and is not described herein again.
The information of the target video comprises an access address of the target video, the client can acquire the target video through the access address, for example, a user can watch the target video on the client by clicking the access address, the user does not need to manually search the video according to the picture information at the moment, the video acquisition efficiency is high, and the user experience is improved. In addition, the information of the target video may also include a brief description of the target video, which facilitates the user to learn more information.
The client can display the information of the target video on the client after receiving the information of the target video sent by the server. If the user browses the page, under the condition that the client automatically sends the picture information of the page to the server, the client can insert the information of the target video at the tail position of the page after acquiring the information of the target video, so that the user can watch the video by clicking the information of the target video when browsing the tail of the page. If the user actively sends the picture information to the server through the client, the client can display the information of the target video in the interface currently displayed by the client after acquiring the information of the target video. The display mode of the target video may be set according to actual situations, and is not limited herein.
In the embodiment, the client sends the picture information to the server; receiving information of a target video sent by the server; the target video is determined according to a target key frame matched with the picture information in a mapping relation, and the mapping relation comprises a corresponding relation between the target key frame of the video and the target video. Therefore, the time for a user to manually search for the video according to the picture information can be saved by acquiring the target video matched with the picture information and sent by the server, and the video acquisition efficiency is improved.
When sending the picture information to the server, the picture information can be actively sent by the user through the client, or the client can automatically obtain the picture information according to the browsing page of the user and send the picture information to the server, that is, the sending of the picture information to the server includes:
and sending the picture information of the page to a server under the condition of acquiring the page content.
In this embodiment, after acquiring the page content, the client extracts all matches in the page, and filters invalid matches in the matches, for example, filters a text graph, a Logo, or a trademark (i.e., a Logo graph), and finally obtains picture information of the page content.
In the implementation, the client automatically sends the picture information to the server under the condition of acquiring the page content, so that the user does not need to participate, the user operation is simplified, and the user experience is improved.
Further, referring to fig. 4, fig. 4 is a fourth flowchart of a video recommendation method according to an embodiment of the present invention, as shown in fig. 4, the video recommendation method according to the embodiment is applied to a client, and includes the following steps:
In this embodiment, the page list includes access addresses of multiple pages, and the access addresses may be Uniform Resource Locators (URLs). The client can acquire the page content through the access address, and after acquiring the page content, the client extracts all matching images in the page and filters invalid matching images in the matching images, for example, filtering a character image, a Logo or a trademark (i.e., a Logo image), and finally acquires picture information of the page content.
The step is consistent with the record in step 302, and the specific reference may be made to the record in step 302, which is not described herein again.
And 403, displaying the information of the target video on one side of the page information of the page in the page list.
The page information may include a title of the page, or a portion of the content of the page. The one side of the page information may be any one side of the page information display position, for example, an upper side, a lower side, a left side or a right side of the page information display position, and the like, without being limited thereto. Preferably, the information of the target video is displayed in a page list (the page list can be understood as an entry for a teletext) at the lower side of the page information of the page. The information of the target video recommended for the user is displayed on the lower side of the page information of the page, so that the probability of the user for viewing the target video can be increased, and the browsing habit of the user from top to bottom can be better met.
As shown in fig. 4a, fig. 4a is a page list displayed on the client display interface, wherein a title "XXX" of a page 11 is displayed in the page list, and a title "downstairs with a earthquake alarm" of a page 12 is arranged behind the title "XXX" of the page 11; a user clicks the title of the page 11, and the client acquires the page content of the page 11 and displays the landing page of the article; when the user finishes browsing the article landing page and returns to the page where the page list is located, the client displays the information of the acquired target video on the lower side of the title of the page 11. As shown in fig. 4b, between the title of page 11 and the title of page 12, information "XXX: the stage is too big in spring and evening and can be tense when people climb up for three times, and the information of the target video also comprises a cover picture of the target video. By clicking the information, the user plays the video corresponding to the information (i.e., the target video), where reference numeral 33 denotes the information of the target video, reference numeral 331 denotes a play key of the target video, and the target video can be played by clicking the play key.
The image-text information still has a great proportion in the information flow distribution, and after the user reads the image-text information, the user strongly wants to see the video resources of the related contents described in the article matching picture. At present, after reading the image-text information, a user needs to search relevant video resources (such as a television show, an art program and the like) according to a matching picture in an article, and a mechanism for automatically matching and recommending the video resources to the user does not exist.
According to the video recommendation method, the incidence relation is established between the picture information in the article and the short video and long video resources, after the picture information is read, the original video resources of the content of the article are automatically recommended to the user, distribution of the video resources is increased, and the user requirements are met.
The user clicks to enter a certain article for reading, if the matching picture in the article comes from a picture in a certain short video or a long video, the corresponding video can be automatically matched, the list page is returned after the user finishes reading the article, and the matched video can be automatically inserted into the article which is just read for the user to watch.
The video recommendation method in the application comprises the following steps:
extracting frames from a video and establishing a video fingerprint retrieval system from the images to the video, wherein the corresponding relation between the key frames and the video is suggested, namely a mapping relation is obtained;
the method comprises the steps of searching videos in a retrieval system by using pictures in the article, and selecting video resources matched with the contents of the pictures from the videos, wherein the target videos are obtained according to picture information and a mapping relation.
The video fingerprint retrieval system establishes the corresponding relation from the video key frame to the video level. Many relevant videos are retrieved by matching pictures in the text (namely pictures in the text), and whether the videos are matched or not is determined according to the positions of the pictures in the text and the number of the pictures of the same video. The method comprises the following specific steps:
extracting image key frames from all short videos and long videos;
extracting features from the key frames and establishing a feature index;
extracting all matching graphs from the articles;
and identifying and filtering invalid matching graphs, such as: text charts, Logo charts, etc.;
extracting features from the filtered images, and retrieving videos;
filtering the video according to the position of the image in the article and the number of times of the video retrieval, and finally obtaining a matched video;
after the matching relationship between the article and the video is obtained according to the steps, when the user reads the article and returns to the list page, the matched video is automatically displayed behind the article.
In the process, matching information of the article is combined with matching positions and peripheral character information to search matched video resources, and meanwhile, the matched video resources are sequenced through the article information. The method has the advantages that brand-new product experience is brought to the user, the pain point of the user experience is solved, the fluency of the user to information consumption is improved, reasonable flow conversion is carried out, meanwhile, distribution of short videos and long videos is increased, distribution of video resources is increased while the user experience is improved, and the user duration is increased.
