Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The video playing method disclosed by the embodiment of the application can be applied to but not limited to the client of video software, and aims to enable the video software to have richer functions.
Fig. 1 is a flowchart illustrating a video playing method according to an exemplary embodiment, and as shown in fig. 1, the method includes the following steps:
in step S11, in response to the instruction to add an object to the video, an area selection interface is displayed in the current frame image of the video display.
The area selection interface is used for selecting an area from a current frame image of the video.
It will be appreciated that a video is typically a time-ordered sequence of image frames, and thus, a region selection interface may be used to select a region from at least one image frame. The current frame image is a currently displayed frame image, and generally, the current frame image is defaulted to be a first frame image of a video or a randomly determined frame image, and may be any frame image designated by a user. In addition, in this embodiment, the form of the area selection interface is not limited, and reference may be made to the prior art, which will be illustrated in the following embodiments.
In this embodiment, as shown in fig. 2, after receiving an instruction to add an object to a video, a region selection interface is displayed.
In step S12, the selected region in the current frame image is determined according to the input information on the region selection interface.
It is understood that the input information on the area selection interface may be information that is input by a user operating the area selection interface, for example, the user defines an outline on the area selection interface, coordinates of points on the outline are the input information, and a closed area surrounded by the points is the selected area. The determination of the selected region in the current frame image may be understood as displaying an outline of the selected region, and it is understood that a display position and a form of the outline of the selected region are not limited.
In step S13, the object is added in the selected area.
In this embodiment, the object is used to present a preset display effect, where the preset display effect may be configured in advance by a user. For example, a sticker of a gust effect is added in the selected area. The specific implementation form of the preset display effect can be referred to in the prior art, and is not described herein in detail.
In step S14, the video to which the object is added is played.
Because the object is added in the selected area in the above steps, a preset display effect presented by the object is displayed in the selected area in the image frame to which the object is added during the playing process of the video.
The method for playing the video, which is described in this embodiment, is different from a method for adding an object to a video in the prior art, in this embodiment, a part of the area in the image frame may be selected to add a display effect, so that a method for playing the video is expanded, and the video software has richer functions.
Fig. 3 is a video playing method according to an exemplary embodiment, and compared with the above embodiments, the selected area is further identified to achieve the addition of the object with finer granularity.
Fig. 3 includes the following steps:
and S31, responding to the instruction of adding the object to the video, and displaying an area selection interface in the current frame image of the video display.
And S32, determining the selected area in the current frame image according to the input information on the area selection interface.
And S33, identifying the target in the selected area.
Wherein, the image may include a background and an object (the definition may refer to the prior art), therefore, in this embodiment, after the region is selected, the object may be further identified from the region. The method aims to realize the selection of a display area with a display effect in a finer granularity, thereby realizing the control of the display effect in a finer granularity.
It will be appreciated that the identified objects may be displayed, and further, that the selected region and the identified objects may be displayed simultaneously. For example, a mask is displayed in the image frame, and in the mask, the selected region and the object in the selected region are displayed distinctively.
It will be appreciated that the type of target may be pre-configured and the recognition algorithm may be as per the prior art.
Alternatively, when a plurality of objects are recognized from the selected region, the object having the largest display area ratio in the selected region is set as the recognized object. For example, when a plurality of birds are recognized from the selected area, the bird whose display area is the largest in the selected area is targeted for recognition, and the purpose is to add objects with fine granularity and avoid the problem of a disordered display effect due to the addition of the objects.
And S34, adding the object on the target.
It will be appreciated that one common implementation of adding objects to a target is: the object is superimposed on the target.
Alternatively, if no target is identified in the selected region, the selected region may be targeted.
And S35, playing the video with the added object.
In this embodiment, since the target is further recognized from the selected region, a display effect can be added to the target in the video, and control of a finer-grained display effect is realized compared with the region.
One example of how to distinguish between adding objects to the selected area and adding objects to the target is: the object is added to the selected area, so that the tracking of the face area can be realized, the face area is displayed with highlight effect in all image frames in the video, the object is added to the target, the eyes in the face can be further recognized, the eyes are displayed with highlight effect in all image frames in the video, and the fine-grained control of the display effect is realized. Further, since the eye area is smaller, the user may have difficulty in selection, and the target is recognized from the area as long as the type of the target is previously configured, the user selects the area including the eye, and thus, convenience is provided for the user's operation.
It will be appreciated that it is also possible to track both the selected region and the target, in which case if the target appears outside the selected region, another display effect different from the above-described display effect may be presented, thereby making the software more functional.
As described above, since a video is composed of a plurality of image frames, in order to facilitate user operation, an object can be added to the plurality of image frames by using a recognition technique depending on a region selected by a user in one image frame.
Fig. 4 shows a video playing method according to an exemplary embodiment, which includes the following steps:
in step S41, in response to an instruction to add an object to a video, an area selection interface is displayed in a current frame image of the video.
In step S42, the selected region in the current frame image is determined according to the input information on the region selection interface.
In step S43, objects in the selected area are identified.
In step S44, an image frame satisfying a preset condition among the image frames of the video is determined as a candidate image frame.
In this embodiment, the preset condition is that the preset condition corresponds to the target time window, that is, in the playing process, the image frame played in the target time window is the candidate image frame. The target time window may be predetermined.
Optionally, the target time window may be determined in any one or a combination of the following manners:
1. a trigger operation based on a user selected time window.
That is, an interactive interface may be displayed, and the user selects a time window on the interactive interface, and the time window selected by the user is taken as a target time window. For example, a sliding window with a fixed length is displayed on the interactive interface, and the user can slide the sliding window on the image frame sequence of the video to select the starting and ending positions of the sliding window, so that the target time window is determined. The method can realize human-computer interaction to determine the target time window, and has higher flexibility.
2. Based on the preset display duration of the object.
Since the object is added to the video, in order to enable the object to be completely presented in consideration of the display duration of the object itself, optionally, the length of the target time window needs to be not less than the display duration of the object itself (since the object is generated by pre-configuration, the display duration of the object itself may be referred to as a preset display duration).
3. Based on the display time stamp of the current frame image.
Specifically, since the object is determined to be added to the current frame image, the current frame image may be used as a starting position, an intermediate position, or an end position of the object presentation, that is, the current frame image may be used as a first frame image, an intermediate frame image, or a last frame image in the target time window, so as to improve the continuity of the object in the video. In practice, the position of the current frame image in the target time window may be configured in advance.
The above three points are ways of determining the target time window from three different dimensions, and it can be understood that the three ways can be used alone or in combination, and the following are examples of several combinations:
1. based on the trigger operation of the time window selected by the user and the preset display duration of the object:
in this way, it is necessary to define a lower limit for the user-selected duration, i.e., to define the user-selected duration to be not less than the preset display length of the object.
For example, a sliding window with a fixed minimum length is displayed on the interactive interface, and the minimum length of the sliding window is a preset display duration of the object. The user may slide the sliding window over the sequence of image frames of the video to select the start-stop position of the sliding window. I.e. the image frames included in the sliding window, are candidate image frames. In addition, the user can also extend the length of the sliding window to enable the target time window to be larger than the preset display duration of the object, but cannot shorten the sliding window to enable the target time window to be smaller than the preset display duration of the object. In summary, the user can determine the target time window by operating the sliding window with a fixed minimum length.
2. Based on the preset display duration of the object and the display timestamp of the current frame image.
In this case, if it is to be ensured that the length of the target time window is not less than the preset display duration of the object, it is required that the time length between the current frame image and the last frame image of the video is not less than the preset display duration of the object.
And in the case that the time length between the current frame image and the last frame image of the video is less than the preset display duration of the object, determining the target time window based on the time length from the current frame image to the last frame image, wherein one example is as follows: and taking the display time from the current frame image to the last frame image as a target time window. In this case, it is also possible to add an object in a frame designated by the user, and it is also possible to ensure display duration adaptation for the object.
In step S45, the identified object in the selected region is identified in the candidate image frame.
In step S46, the candidate image frame in which the target is identified is set as the target image frame.
In step S47, an object is added to the target in the target image frame and the current frame image.
In step S48, the video to which the object is added is played.
The flow shown in fig. 4 achieves the purpose of adding objects to the targets in the plurality of image frames by the tracking technology, and achieves batch display of the display effect. In addition, the object can be added to a plurality of image frames by selecting the selected region once, so that the method has high convenience.
In the following, from the perspective of an interactive interface of video software, an application of the video playing method disclosed in the present disclosure to the video software will be described with emphasis.
Specifically, a new type of sticker is added in the sticker function of the existing video social software, and for convenience of description, the new sticker is hereinafter referred to as a special-effect sticker. Before the following process, it is assumed that the software has been triggered to enter a sticker function interface according to the operation of the user on the software, and icons of various types of stickers are displayed in the sticker function interface, such as "special effect", "hot door", "holiday", and "record" shown in fig. 6a, the user may select an icon of any type of sticker, and after clicking, the software displays the icon of each sticker under the type of sticker, and in this embodiment, it is assumed that the user clicks the icon of the special effect sticker. For example, in fig. 6a, the stickers under the "special effect" sticker are "ancient wind", "frozen time", "cartoon", "hand-drawing", "haar mirror", etc. The user can select an icon of any one of the stickers, and after clicking, the software receives an instruction of adding the sticker serving as an object in the video. In this embodiment, it is assumed that the user clicks "ancient wind".
Fig. 5 shows a video playing method according to an exemplary embodiment, which includes the following steps:
in step S51, in response to an instruction to add a special effect sticker to a video, an area selection interface is displayed on a current frame image of the video.
Alternatively, in fig. 6b, a mask is displayed on the image frame, and the guidance information is displayed on the mask: and drawing the region which you want to act on the picture. Furthermore, a "cancel" button is displayed in the lower left corner of the masking layer, the drawing state is exited after clicking, the interface shown in fig. 6a is returned, a "confirm add" button is displayed in the lower right corner of the masking layer, and clicking is not available when no pattern is drawn.
Because the area selection interface is displayed on one image frame, the content of the video playing area in the interface is in a static state, and the user can conveniently perform selection operation.
As previously mentioned, in this embodiment, the user has selected the "antique" special effect sticker.
In step S52, the selected region, i.e., the determined selected region, is displayed on the image frame according to the input information generated by the user drawing the region on the region selection interface, as shown in fig. 6 c.
It will be appreciated that the start point and the end point are connected closed if the user does not draw a closed pattern, starting from when the user's finger touches the screen and ending with the finger off the screen. After the user finishes one drawing, the drawn curve is displayed on the area selection interface, and after the user clicks the 'confirm add' button, the following steps are executed, and after the user clicks the 'cancel' button, the interface shown in fig. 6a is returned to.
In step S53, the target is obtained by performing target recognition on the selected region.
The target identified in fig. 6c is a cat head.
It will be appreciated that the user may select the display effect before the selected region is rendered, as shown in figure 6b, or after the rendering, as shown in figure 6 c.
It will be appreciated that the user may change the sticker without the selected area changing before proceeding to the next step.
In step S54, a plurality of image frames in the target time window selected by the user are acquired as candidate image frames.
In fig. 6d, the image frame selection interface and the image frame after the sticker is added are displayed simultaneously, and the user determines a target time window through a sliding window in the image frame selection interface to select a plurality of image frames. The configuration of the sliding window can be referred to the above embodiments, and is not described here.
In step S55, when the instruction to add an object to the video is received again, the area selection interface is redisplayed in the current frame image.
Also taking fig. 6d as an example, in the case of displaying the image frame after adding the antique sticker in fig. 6d, if the user clicks again the antique sticker icon in the sticker list, indicating that the user needs to redraw the selected area, it can be seen from fig. 6d that S55 can facilitate the update of the display effect by returning to fig. 6 b.
It will be appreciated that in fig. 6d, if the user clicks on the selected region (and/or target), the boxed line of the region may be displayed, as shown in fig. 6e, and a delete marker may also be displayed, which the user clicks on to delete the effect sticker.
In step S56, after the user completes setting of the special effect sticker, the target in the candidate image frame is recognized, and after the object sticker is added to the target, the video to which the special effect sticker is added is played.
Specifically, in a plurality of image frames selected by the user, a special effect of the ancient wind is added in the cat head area, and in the case that a certain image frame of the plurality of image frames selected by the user does not have a cat head, the original image frame is played. And the image frames which are not selected by the user play the original image frames.
As can be seen from the flow shown in fig. 5, the video playing method described in this embodiment is combined with the sticker function of the existing video social software, so that the sticker function can be expanded, and richer stickers can be obtained.
Compared with the existing paster, the special-effect paster has the special-effect which the existing paster does not have.
It should be noted that, in the above embodiment, before playing the video to which the object is added, it is also possible to: and receiving configuration data of the video display style, wherein the configuration data is used for presenting the video with a preset style. The preset style may be a style applied to the entire picture of the video.
The display effect may be an existing display effect that can be added to the whole image frame. For example, each special effect under the special effect sticker is a special effect applied to the whole image frame by the existing video social software. In the present disclosure, these special effects can also be applied locally, so on one hand, the individuation of the video can be maintained in addition to the special effect brought by the software. On the other hand, by combining the region or the target with various special effects, more display modes can be realized, such as co-location of a two-dimensional picture and a three-dimensional picture, static and static content of a part of the picture and the like. In the third aspect, the display effect currently applied to the whole world, including special effects, magic methods, props and the like, can be used in combination with the selected area, so that the method disclosed by the disclosure has higher compatibility with the prior art and is easy to implement.
In conclusion, the method disclosed by the disclosure can be beneficial to catalyzing personalized videos, so that the software has better ecology and users have better experience.
