In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a video processing method applied to electronic devices, which include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of Mobile Stations (MSs), Terminal devices (Terminal devices), and so on.
The method comprises the following steps:
The video to be processed is a pre-recorded video or a video acquired in real time in the process of a video call between the sending end and the receiving end. After being processed, the video to be processed is sent to a receiving end by a sending end.
And performing image recognition on the first video frame in the video to be processed, and identifying an object in the video, wherein the object can be a person, an animal or a still object. After identifying the object, extracting characteristic parameters of the object; the characteristic parameters include the type of the object, the distance to the photographing apparatus, the distance to another object, and the like. Object types such as people, animals, or still, etc.
And determining a target object according to the characteristic parameters, wherein the target object is a main object in the first video frame. Optionally, or objects pre-labeled as target objects; or the characteristic parameter of the target object may be an object closest to the shooting device, for example, if the object is a person, the person closest to the call device may be determined to be a subject person in a video call scene or a live network scene.
Wherein the characteristic parameters include at least one of: a first distance between an entity object corresponding to the object and the electronic equipment, a second distance between the entity object corresponding to the object and a main target entity object, a single occurrence time of the object in the video to be processed, and a preset mark of the object; wherein the primary target entity object corresponds to a primary target object of the target objects; the object may be an object in a video frame of a video to be processed, and may be a person, an animal, a still object, or the like, and the entity object is a real object in a real environment corresponding to the object, such as a person corresponding to the person, and an object real object corresponding to the object.
It is understood that, in the embodiment of the present invention, the distance-related parameters, such as the first distance and the second distance, are physical distances between the physical objects or between the physical objects and the electronic device; and the target object and the non-target object refer to the image of each entity object in the video.
As a first example, referring to fig. 2, the above characteristic parameters are introduced in the scene of fig. 2, where M denotes a photographing device which is a photographing device of a video to be processed, A, B, C are three solid objects within the photographing range of the photographing device, respectively; d is the entity object outside the shooting range, and the shooting equipment cannot shoot the entity object D; da is a first distance between the physical object a and the photographing apparatus, db is a first distance between the physical object B and the photographing apparatus, and dc is a first distance between the physical object C and the photographing apparatus; if the entity object a is the main target entity object of the main target object, the second distance of the entity object B is the distance between the entity object B and the main target entity object a, i.e. d1 in fig. 2; the second distance of the entity object C is the distance between the entity object C and the main target entity object a, i.e. d2 in fig. 2.
Alternatively, in the process of determining the target object by the shooting device, a filtering range may be set, as shown in fig. 2, in a range with the shooting device M as the center and the radius R as a circle, and objects in the range are preferentially selected as the identified objects.
Specifically, during the process of recording the video to be processed, the shooting device may determine, by using a target detection technology, a first distance of each entity object relative to the shooting device and a second distance between each entity object and a main target entity object, or take a difference between the first distances of the two as the second distance of the two; when the shooting device obtains the first distance and/or the second distance of each object, the first distance and/or the second distance can be carried in the first video frame as a characteristic parameter.
And if the object appears in the video to be processed for multiple times, the single-appearing time length is not accumulated.
The objects may have a preset tag, for example, some objects may be pre-tagged as target objects or non-target objects.
The non-target object, i.e. the non-subject object in the first video frame, may be determined according to a characteristic parameter of the object, for example, an object farther from the shooting device, or an object that is pre-marked as a non-target object.
In addition, after determining at least one target object, further searching for other target objects in the first video frame based on the characteristic parameters of other objects; such as an object that is closer to the target object.
After the non-target object is determined, performing replacement or coverage processing on the non-target object; for example, taking the covering process as an example, the mosaic process is performed on the non-target object, so that the details of the color level of the region where the non-target object is located are degraded, the color blocks are disturbed, and the covering is performed through the mosaic; taking replacement processing as an example, replacing the area where the non-target object is located by using a preset mark, for example, firstly performing matting processing on pixel points of the area where the non-target object is located, and then filling the preset mark in the area subjected to the matting processing to complete the replacement processing, so as to avoid the situation that the privacy of a video call user or the non-target object is revealed because the non-target object is displayed in a video to be processed.
Alternatively, for a video frame to be processed, a processing period may be set, such as several seconds each; in a processing period, a frame of image is selected as a first video frame, after a target object and a non-target object are identified based on the first video frame, the non-target object in the video frame in the processing period is replaced or covered, and the identification of each frame of image is not needed, so that the image processing operation amount of the electronic equipment is reduced.
In order to ensure the image processing precision, each frame of image in the video to be processed can be identified; the specific identification manner may be set by a user, and the embodiment of the present invention is not limited herein.
And sending the processed video frame or the complete video to a receiving end, so that a receiving end user cannot check the non-target object when checking the video frame or the video, and the privacy of the user is effectively protected.
In the embodiment of the invention, a characteristic parameter of an object in a first video frame of a video to be processed is determined, a target object and a non-target object are determined according to the characteristic parameter, and the non-target object in the first video frame is replaced or covered; and performing replacement or covering processing on the non-target object to replace or cover the non-target object in the first video frame, so that the non-target object is prevented from being displayed in the first video frame and the processed complete video, and privacy disclosure of a user is prevented in the processes of video calling, live broadcasting, recorded broadcasting and the like. The embodiment of the invention solves the problem that in the prior art, the privacy of a user is poor in the video call process.
Optionally, in an embodiment of the present invention, the step of determining the target object according to the feature parameter includes:
if the characteristic parameter of the object meets at least one of the following identification conditions, determining that the object is a target object, wherein the identification conditions include:
condition one, the first distance is less than a first distance threshold or the first distance of the object is the smallest value of the first distances.
For example, a first distance threshold is set, for example, the first distance threshold is 1 meter, and then objects corresponding to physical objects less than 1 meter away from the shooting device are all taken as target objects; it can be understood that there may be one or more target objects, and if the number of the target objects is one, the object closest to the shooting device may be selected as the target object, that is, the object with the smallest value in the first distance is the main target entity object, see fig. 2, and the object with the smallest first distance is the entity object a.
Conditional two, the second distance is less than a second distance threshold.
If the first video frame has a target object which is marked as a target object in advance or is identified, further searching a new target object according to the target object; specifically, searching for an object whose second distance from the main target entity object is smaller than a second distance threshold, referring to fig. 2, if the entity object a is identified as a target object, further searching for a second distance between each object to be identified and the main target entity object of the known target object, and if the second distance is smaller than the second distance threshold, determining that the object to be identified is the target object; alternatively, the second distance threshold may be a distance value of less than 1 meter, such as 0.5 meter.
And thirdly, the single-occurrence time length is larger than or equal to the first time length threshold.
For example, if an object to be identified exists in the to-be-processed video, where the single-occurrence time length of the object is greater than or equal to the first time length threshold, for example, the first time length threshold is 2 minutes, after the single-occurrence time length in the current to-be-processed video reaches 2 minutes, the object is marked as a target object. Taking the electronic equipment as shooting equipment as an example, when a lens captures a distinguishable object in the process of video call, the electronic equipment extracts object features and establishes a unique number, such as M, for the object; when the accumulated staying time of the object M in the unit time t exceeds s (for example, within 30 seconds, the accumulated staying time exceeds 20 seconds), the object M is determined as a participant, namely the target object, otherwise, the object M is determined as a non-participant.
Conditional four, the preset mark includes a mark of the target object.
If the object to be identified in the first video frame is marked as the target object in other video frames of the video to be processed, the object is directly determined as the target object.
Optionally, in this embodiment of the present invention, after determining that the target object is the target object according to the characteristic parameter, the method further includes:
detecting that a first object disappears from a video frame of the video to be processed, and recording the disappearance duration of the first object, wherein the first object is the target object;
determining a target characteristic parameter of the first object under the condition that the first object appears in the video to be processed again and the disappearance duration is greater than or equal to a second duration threshold, and determining that the first object is a target object or a non-target object according to the target characteristic parameter;
and under the condition that the first object appears in the video to be processed again and the disappearance duration is less than a second duration threshold, determining that the first object is a target object.
The first object disappears from the video frame of the video to be processed, for example, in the video call process, if the first object leaves the video call picture, the disappearance duration of the first object is recorded; if the single-disappearance duration is greater than or equal to the second duration threshold, for example, the second duration threshold is 10 minutes, the characteristic parameters of the object are identified again if the first object disappears for more than 10 minutes.
Specifically, taking the electronic device as a shooting device as an example, when a lens captures a recognizable object in the process of video call, the electronic device extracts object features and establishes a unique number, such as M, for the object; when the accumulated staying time of the object M in the unit time t exceeds s (for example, within 30 seconds, the accumulated staying time exceeds 20 seconds), the object M is determined as a participant, namely the target object, otherwise, the object M is determined as a non-participant. After the target object identity of M is identified, the identity of a participant has a period of validity h, and h is a second duration threshold; when the M leaves the lens, timing is started, when the M returns to the lens within the validity period h, the identity of a participant is automatically obtained, re-identification is not needed, timing returns to zero, and timing is re-performed when the M leaves next time; and when the time that M leaves the lens exceeds h, losing the identity of the participant, changing the participant into a non-target object, and identifying according to the characteristic parameters such as the stay time, the first distance or the second distance and the like.
Optionally, in an embodiment of the present invention, the step of replacing or overlaying the non-target object in the first video frame includes:
determining a region to be processed of the non-target object in the first video frame;
replacing or overlaying the non-target object in the first video frame with a target image; the target image is a first image or a preset second image, the first image is an image of a second video frame in the video to be processed at the same position as the area to be processed, for example, by acquiring other image frames in the video to be processed, if the object does not exist in the same area or a corresponding area and only a background area exists, the same area of the image is intercepted as an overlay image to replace or overlay the area to be processed in the first video frame.
The preset second image can be a cartoon image or other preset images, and the second image directly covers the area to be processed.
In addition, the mosaic processing can be carried out on the area to be processed so as to cover the non-target object.
Optionally, in the embodiment of the present invention, if the electronic device is a sending end or a server of the to-be-processed video;
after the step of replacing or overlaying the non-target object in the first video frame, the method comprises:
and sending the target video subjected to the replacement or the coverage processing to a receiving end of the video to be processed.
As a second example, referring to fig. 3, if the electronic device is a sending end of a to-be-processed video, such as one end of a video call, or a live webcast anchor, fig. 3 shows an application process in which the electronic device is a sending end, and mainly includes the following steps:
and step 301, acquiring a video image.
Optionally, in a case that the electronic device is a sending end, a display interface of the sending end may display a video to be processed, may also display a processed video, or provide a switch key for a user to switch.
If the electronic equipment is a server, namely, the to-be-processed video sent by the sending end is received, the electronic equipment executes the video processing method in the embodiment of the invention on the to-be-processed video, and then sends the processed video to the receiving end; as a third example, referring to fig. 4, fig. 4 shows an application process in which the electronic device is a server, and mainly includes the following steps:
In step 402, the server analyzes each frame of image in the video to be processed.
And step 403, extracting a target object and a non-target object in each frame of image.

Optionally, or objects pre-labeled as target objects; or the characteristic parameter of the target object may be an object closest to the shooting device, for example, if the object is a person, the person closest to the call device may be determined to be a subject person in a video call scene or a live network scene.
Wherein the characteristic parameters include at least one of: the first distance between the entity object corresponding to the object and the electronic device, the object may be an object in a video frame of a video to be processed, and may be a person, an animal, a still object, or the like, and the entity object is a real object in a real environment corresponding to the object, such as a person corresponding to a portrait, an object corresponding to a portrait, and a real object.
A second distance between an entity object corresponding to the object and a main target entity object, a single occurrence time of the object in the video to be processed, and a preset mark of the object; wherein the primary target entity object corresponds to a primary target object of the target objects.
As a first example, referring to fig. 2, the above characteristic parameters are introduced in the scene of fig. 2, where M denotes a photographing device which is a photographing device of a video to be processed, A, B, C are three solid objects within the photographing range of the photographing device, respectively; d is the entity object outside the shooting range, and the shooting equipment cannot shoot the entity object D; da is a first distance between the physical object a and the photographing apparatus, db is a first distance between the physical object B and the photographing apparatus, and dc is a first distance between the physical object C and the photographing apparatus; if the entity object a is the main target entity object of the main target object, the second distance of the entity object B is the distance between the entity object B and the main target entity object a, i.e. d1 in fig. 2; the second distance of the entity object C is the distance between the entity object C and the main target entity object a, i.e. d2 in fig. 2.
