Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a video sequence processing method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
In this embodiment, the number of videos in the first video sequence is greater than 1, that is, the first video sequence is a video set including a plurality of videos, and may include two videos, three videos, five videos, and so on, and the specific number is not limited herein.
Specifically, the video sets including the multiple videos are arranged according to a certain order to form the first video sequence, where the multiple videos in the video sets may be arranged according to content similarity, may also be arranged according to the same or different of publishers, and may also be arranged according to an order of number of clicks of a user or a number of views of a user, it is understood that the order of arrangement of the multiple videos in the video sets is not fixed, but may be arranged according to any order, and is not limited herein.
In this embodiment, the first video sequence includes a first video, and the first video is not limited to the first video in the first video sequence, and may be any video in the first video sequence, which is not limited herein.
In this step, there are various ways to obtain the first video sequence, for example, a plurality of videos may be randomly selected from a video pool, or a plurality of videos may be selected from the video pool according to a preset rule, and then the first video sequence is composed, for example, one video of type a, two videos of type B, and 3 videos of type C are selected from the video pool, and then the first video sequence is composed.
In addition, the first video sequence may also be obtained according to a personalized recommendation algorithm, for example, the first video sequence is obtained through processes of recall, rough ranking, fine ranking, duplicate removal and the like in combination with features of the user and features of the video. The recall method includes methods such as collaborative filtering, FM (factor decomposition), FFM (Field-Aware decomposition), deep learning, and the like, and the processes such as coarse ranking, fine ranking, and the like may also include methods such as filtering, decomposition, and deep learning. The method in the embodiment can be adapted to various personalized recommendation methods, which is also an advantage of the embodiment.
In this embodiment, the step of interleaving the target popularization information in the first video sequence may include: and according to the determined target popularization information, determining a proper popularization information insertion position in the first video sequence, and inserting the target popularization information into the corresponding position.
When the target promotion information can also be temporarily undetermined promotion information, determining the target promotion information with proper insertion position in the target promotion information set according to the insertion positions in the first video sequence, and inserting the target promotion information into the corresponding positions.
In this embodiment, the second video sequence is a video sequence interspersed with the target popularization information, that is, the second video sequence may include a plurality of videos and at least one target popularization information, and the video sequence processing method described in this embodiment may be used for processing each interspersing of the target popularization information.
Wherein the target promotion information is adjacent to the first video. Preferably, the target promotion information is located after the first video.
In this step, according to the emotion characterization parameters of the target promotion information, the difference delta between the emotion characterization parameters of the target promotion information and the emotion characterization parameters of each video is calculated in a first video sequence in a sequence from front to back or in a sequence from back to front, and the video with the minimum delta is used as the first video, so that the position adjacent to the first video is used as the position meeting the requirement.
In this embodiment, the fact that the target popularization information is adjacent to the first video may mean that the target popularization information is located behind the first video, or that the target popularization information is located in front of the first video, which is not limited herein.
In this embodiment, the emotion characterization parameter is used to characterize a parameter that affects the emotion of the user by the video or the promotion information.
The emotion characterization parameters can represent the degree of influence of the video or the promotion information on the emotion of the user, and the emotion characterization parameters corresponding to different degrees are determined in a grading mode. The ranking may be represented by Arabic numerals, such as 1-10, or by English letters, such as A-F, or Roman numerals, such as I-V, it is to be understood that the ranking of the emotion characterization parameters is not limited thereto, and for the convenience of understanding, the following description will be made by using Arabic numerals for the emotion characterization parameters.
The emotion characterization parameters can include multiple dimensions, for example, emotion dimensions, which represent emotions expressed by videos or popularization information contents, for example, the emotion expressed by a laughing video is happy, the emotion expressed by a warning video is sad, the emotion expressed by a suspensory video is nervous, the emotion expressed by a horror video is panic, and the like; the picture dimension represents the frequency of picture or shot switching of the video or promotion information, for example, the moving video picture shot switching is fast, and the cate video picture shot is stable; as another example, the music dimension, representing the style of video or promotional information background music, is fierce or relaxed; for example, the color dimension indicates the chroma of the video or the promotion information screen, whether it is warm or cool, whether it is bright or dark, and the like. Based on the consideration of multiple dimensions, the video or the promotion information can be marked with different emotion characterization parameters in a more subdivided manner, for example, the emotion dimensionalities are divided into A1 and A2. ANG. An, the color dimensionalities are divided into D1 and D2. ANG. Dm, a plurality of emotion characterization parameters form An emotion characterization parameter set, and the video or the promotion information is marked with emotion labels in multiple dimensions. It is understood that the dimensions of the emotion characterization parameters are not limited thereto, and are not limited thereto.
In this embodiment, the emotion characterization parameters of each video or promotion information may be determined through an algorithm, the emotion characterization parameters may also be manually marked on the video or promotion information samples, a model may also be obtained through machine training, and then the emotion characterization parameters are automatically marked on all videos or promotion information through the model.
In addition, the emotion representation parameters of each video or promotion information may be acquired in advance, or may be acquired by temporarily using a model in this step.
If the emotion representation parameters of each video or the promotion information are obtained in advance, a label of the emotion representation parameter can be added to each video or the promotion information, and thus each video or the promotion information carries the label of the emotion representation parameter, and the corresponding emotion representation parameter can be obtained while the first video sequence and the target promotion information are obtained. By adding the label of the emotion representation parameter to the video or the promotion information, the convenience of obtaining the emotion representation parameter can be improved.
Of course, a database for storing the emotion characterization parameters may also be provided, where the emotion characterization parameters of each video or promotion information are stored in the database, and each emotion characterization parameter carries a video identifier or a promotion information identifier. For example, if the emotion representation parameter of the video a needs to be acquired, the video sequence processing apparatus searches the emotion representation parameter carrying the video a identifier from the database, and uses the emotion representation parameter as the emotion representation parameter of the video a.
The mode of obtaining the emotion representation parameters of each video or promotion information can be realized through a model. Specifically, each video or promotion information can be input into the model, the emotional feature extraction is performed on the picture content of the video, the music of the video or the color of the video through the model to obtain an emotional feature matrix, and the normalization processing is performed on the emotional feature matrix to obtain the emotional characterization parameters of each video or promotion information. The emotion characterization parameters of each video or promotion information obtained through model calculation can be stored in a database, and the data format in the database can be video identification, emotion characterization dimensionality and score. The model may be a model created in advance, or may be a model obtained by inputting video data into a convolutional neural network and training the convolutional neural network, which is not limited in this embodiment.
Various manners of obtaining the emotion representation parameters of each video or promotion information are not listed here.
In this embodiment, the preset amplitude is a preset threshold, and the variation amplitude between the emotion characterization parameter of the target popularization information and the emotion characterization parameter of the first video is within the threshold range, which indicates that the target popularization information is similar to the emotion characterization of the first video, so that the target popularization information can be inserted into a position adjacent to the first video. Taking an arabic numeral to represent the emotion characterization parameter as an example, the threshold range may be 2, if the emotion characterization parameter of the target popularization information is 3, and the emotion characterization parameter of a certain video in the video sequence is 5, the video may be determined as a first video, and the target popularization information is inserted into a position adjacent to the first video. Here, the variation amplitude between the emotion representation parameter of the target popularization information and the emotion representation parameter of the first video may be understood as a difference obtained by subtracting the emotion representation parameters of the two.
And step 103, outputting the second video sequence.
The video sequence processing method in this embodiment may be implemented by a video sequence processing apparatus, which may be a server or a client.
If the video sequence processing apparatus is a server, step 103 may be understood as that the server sends the second video sequence to the client. Specifically, after the server executes step 101 and step 102, a second video sequence interspersed with the target popularization information is generated, and the second video sequence is sent to the client for the user to watch.
If the video sequence processing apparatus is a client, step 103 may be understood as that the client plays the second video sequence. Specifically, after the client executes step 101 and step 102, a second video sequence interspersed with the target popularization information is generated, and the second video sequence is played for the user to watch.
According to the video sequence processing method, the video sequence processing device and the electronic equipment, the popularization information is inserted into the video sequence according to the emotion representation parameters of the video and the popularization information. Because the variation amplitude between the emotion characterization parameter of the promotion information and the emotion characterization parameter of the adjacent video is smaller than or equal to the preset amplitude, the embodiment of the invention can reduce the contrast between the promotion information and the video, improve the matching degree between the promotion information and the video and further improve the output effect of the video sequence. In this way, the user experience can be improved when the user watches the video sequence.
Referring to fig. 2, fig. 2 is a schematic diagram of another video sequence processing method according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step 201, a first video sequence is obtained, where the first video sequence includes a first video and a second video, and the second video is adjacent to the first video.
In this embodiment, the second video and the first video are adjacent to each other, that is, the second video is located before the first video, or the second video is located after the first video, and preferably, the second video is located after the first video.
It should be noted that the second video is not limited to the second video in the first video sequence, and may be a video adjacent to any first video in the first video sequence, which is not limited herein.
The specific implementation process of this step may be as described with reference to step 101 in the embodiment shown in fig. 1, and is not described herein again.
202, interleaving target popularization information between the first video and the second video to form a second video sequence, wherein the variation amplitude between the emotion representation parameter of the target popularization information and the emotion representation parameter of the first video is smaller than or equal to a preset amplitude, and the variation amplitude between the emotion representation parameter of the target popularization information and the emotion representation parameter of the second video is smaller than or equal to the preset amplitude.
In this embodiment, the step 202 at least includes the following two optional embodiments, and any one of the two optional embodiments may be selected. These two alternative embodiments are described below.
Optionally, the step 202 includes:
acquiring target popularization information, emotion characterization parameters of the target popularization information and emotion characterization parameters of each video in the first video sequence;
determining the insertion position of the target popularization information in the first video sequence according to the emotion characterization parameters of the target popularization information and the emotion characterization parameters of each video in the first video sequence;
and according to the interleaving position, interleaving the target popularization information in the first video sequence to form a second video sequence.
In this embodiment, the target popularization information is one or more determined popularization information, a position where each target popularization information can be inserted into a first video sequence needs to be determined, and a video sequence processing device may obtain the target popularization information, an emotion of the target popularization information, and emotion characterization parameters of videos in the first video sequence, and determine an insertion position of the target popularization information in the first video sequence according to the emotion characterization parameters of the target popularization information and the emotion characterization parameters of the videos in the first video sequence.
The method for acquiring the target popularization information and the emotion characterization parameters of each video in the first video sequence may refer to the description of step 102 in the embodiment shown in fig. 1, and is not repeated here.
For the convenience of understanding the present embodiment, the following is specifically illustrated by example E1:
assuming that an emotion characterization parameter of a target popularization information a is 3 at present, the emotion characterization parameters of each video in the first video sequence are respectively: the video a is 4, the video B is 5, the video C is 1, the video D is 7, the first video sequence is arranged according to the sequence of the video A, B, C, D, and it is required to determine the position where the target popularization information a can be inserted in the first video sequence.
Assuming that the preset amplitude is 2, according to that the variation amplitude between the emotion characterization parameter of the target popularization information and the emotion characterization parameter of the first video is smaller than or equal to the preset amplitude, and the variation amplitude between the emotion characterization parameter of the target popularization information and the emotion characterization parameter of the first video is smaller than or equal to the preset amplitude, it may be determined that: the target popularization information a can be inserted between the video A and the video B, can also be inserted between the video B and the video C, but cannot be inserted between the video C and the video D.
In the embodiment of the invention, the position where the target popularization information can be interspersed can be searched in the first video sequence according to the determined target popularization information, so that the video sequence processing method is more flexible.
Optionally, the step 202 includes:
determining an insertion position of popularization information to be inserted in the first video sequence, wherein the insertion position is a position adjacent to the first video;
acquiring target popularization information according to the emotion characterization parameters of the first video and the emotion characterization parameters of the candidate popularization information;
and according to the interleaving position, interleaving the target popularization information in the first video sequence to form a second video sequence.
In this embodiment, an insertion position where promotion information is to be inserted is determined in the first video sequence, target promotion information that can be inserted in the adjacent position of the first video needs to be determined for the adjacent position of the first video, and the video sequence processing device may obtain the target promotion information from the candidate promotion information according to the emotion characterization parameters of the first video and the emotion characterization parameters of the candidate promotion information, and insert the target promotion information into the first video sequence according to the insertion position to form a second video sequence.
When the first video sequence includes a second video, the video sequence processing apparatus further needs to select appropriate target promotion information from the target promotion information set according to the emotion characterization parameter of the second video.
In this embodiment, the determining manner of the insertion position where the promotion information is to be inserted in the first video sequence may include multiple manners: for example, the puncturing position where the promotion information is to be punctured may be determined according to the number of videos of the first video sequence, for example, a position in the middle of the first video sequence may be determined as the puncturing position where the promotion information is to be punctured, and if the number of videos of the first video sequence is 10, a position between the fifth video and the sixth video may be determined as the puncturing position where the promotion information is to be punctured; the insertion position of the popularization information to be inserted can be randomly determined; and so on.
The obtaining method of the emotion characterization parameters of the first video and the second video and the emotion characterization parameters of the candidate popularization information may refer to the description of step 102 in the embodiment shown in fig. 1, and details are not repeated here.
For the convenience of understanding the present embodiment, the following is specifically illustrated by example E2:
suppose that there exists a first video sequence, wherein the emotion characterization parameters of each video are: the video A is 4, the video B is 5, the video C is 1, the video D is 7, the first video sequence is arranged according to the sequence of the video A, B, C, D, and target popularization information which can be inserted between the video A and the video B needs to be determined.
If the preset amplitude is 2, according to that the variation amplitude between the emotion characterization parameter of the target popularization information and the emotion characterization parameter of the first video is smaller than or equal to the preset amplitude, and the variation amplitude between the emotion characterization parameter of the target popularization information and the emotion characterization parameter of the first video is smaller than or equal to the preset amplitude, it may be determined that: in the target popularization information set, target popularization information with emotion characterization parameters of 3-7 can be inserted between the video A and the video B.
In the embodiment of the invention, the target promotion information suitable for the insertion position can be found according to the determined insertion position in the first video sequence, so that the video sequence processing method is more flexible.
Optionally, in the first video sequence, the videos are sorted according to the sequence of the emotion representation parameters from small to large or from large to small; and the emotion representation parameter of the target popularization information is positioned between the emotion representation parameter of the first video and the emotion representation parameter of the second video.
In this embodiment, the emotion characterization parameters of each video in the first video sequence are ordered in sequence, that is, the emotion change of each video in the first video sequence in this embodiment is gradual and gradual, at this time, the target popularization information in which the emotion characterization parameters are located between the emotion characterization parameters of the first video and the emotion characterization parameters of the second video may be directly inserted, so that the effect of gradual and gradual emotion between the videos and the popularization information may be achieved.
It should be noted that, the emotion characterization parameters of each video in the first video sequence are sorted in order, taking arabic numerals as an example, the emotion characterization parameters may be sorted in a descending order or in an ascending order, and are not limited herein.
For the convenience of understanding the present embodiment, the following is specifically illustrated by example E3:
suppose that there exists a first video sequence, wherein the emotion characterization parameters of each video are: the method comprises the steps that a video A is 1, a video B is 4, a video C is 5, a video D is 7, a first video sequence is arranged according to the sequence of a video A, B, C, D, target popularization information with emotion characterization parameters of 1-4 can be inserted between the video A and the video B, and target popularization information with emotion characterization parameters of 5-7 can be inserted between the video C and the video D.
That is to say, in this embodiment, in a case that the emotion representation parameters of each video in the first video sequence are sorted in order, the change amplitude between the emotion representation parameter of the target popularization information and the emotion representation parameter of the first video does not only need to satisfy the condition that the change amplitude is smaller than or equal to the preset amplitude, but also the direction of the change of the emotion representation parameter between the target popularization information and the first video needs to be consistent with the change direction of the emotion representation parameter in the first video sequence.
the specific implementation process of this step may refer to the description of step 103 in the embodiment shown in fig. 1, and is not described herein again.
In the embodiment of the present invention, various optional implementations are added to the embodiment shown in fig. 1, so as to further improve the flexibility of the video sequence processing method.
