Description

Video processing method and device, electronic equipment and storage medium

Technical Field

The present disclosure relates to the field of image processing technologies, and in particular, to a video processing method and apparatus, an electronic device, and a storage medium.

Background

With the rise of mobile internet and the development of video industry, video service scenes of mobile terminals are increasing. The subjective quality of the video at the mobile terminal will directly affect the viewing experience of the user. The subjective quality of a video refers to the subjective feeling of a user on the viewed video, and includes the definition, brightness, saturation, contrast, whether the video is stuck, whether a block effect exists, whether snowflakes exist, whether a picture is coherent and the like.

Some factors that affect the mobile end user viewing experience may sum up as: 1. quality of the original video. The better the quality of the original video, the clearer the video is seen by the user. 2. Network conditions. When the network condition is better, the video seen by the user is closer to the original video, and when the network condition is not good, the situations of picture blockage, blocking effect, snowflake screen or partial picture loss and the like can occur. 3. And (4) a player. In the case that the original video quality and the network condition are the same, the player itself will also affect the viewing experience of the user. The pictures rendered by the player may have different definitions, brightness, saturation, contrast, etc.

However, in the related art, the mobile end player generally adopts fixed picture rendering parameters adjusted in advance, and does not perform other enhancement processing on the video. However, the quality of different video data may also be different, which may result in poor visual effect of the final rendered video picture.

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.

Fig. 1 is a flowchart illustrating a video processing method according to an exemplary embodiment, where the video processing method may be used in an electronic device such as a mobile phone or a notebook, as shown in fig. 1, and includes the following steps.

In step S11, a video stream transmitted by the network is received.

In the embodiment of the disclosure, a playing architecture is provided in which video post-processing is added to a video player of a user terminal, so that before rendering and playing a video stream, the video stream is enhanced by a preset video processing algorithm, thereby improving a visual effect of the final rendering and playing of the video stream, and improving the experience of a user watching the video. First, a video stream to be rendered and played, which is transmitted by a network, needs to be received, and in the embodiment of the present disclosure, the video stream may be obtained in any available manner, which is not limited to the embodiment of the present disclosure.

For example, the video stream may be a video stream acquired by a camera in real time, or a video stream stored in a video server, and so on, and accordingly, the video stream sent by the camera or the video server may be received. Moreover, if the initially acquired video stream is encoded in advance before the video stream is transmitted to the user terminal for rendering and playing the video stream by the camera, the video server and the like, the user terminal receives the encoded video stream corresponding to the original video stream at this time, and then the encoded video stream can be decoded by a corresponding decoder, so that the decoded video stream is obtained and used as the video stream received by the corresponding user terminal and used as the video stream which needs to be enhanced currently; if the user terminal receives the video stream without encoding, the decoding process for the received video stream may not be required.

In addition, in the embodiment of the present disclosure, before the original video stream obtained by initial acquisition is encoded, some simple preprocessing may be performed on the original video stream in advance, but the preprocessing at this time cannot estimate the situation of the video stream during subsequent actual display, so that it cannot be adjusted in a targeted manner, and in the process of encoding and decoding, some negative effects may be generated on the video stream, for example, video data may be damaged. Therefore, in the embodiment of the present disclosure, the currently received video stream may be further enhanced and adjusted before being rendered and played.

In step S12, performing enhancement processing on the video stream through a preset video processing algorithm to obtain a target video stream; and when the video stream is subjected to enhancement processing through the video processing algorithm, the value of the video processing parameter in the video processing algorithm is obtained by setting according to the video stream.

In order to improve the visual effect of the video stream during display, the video stream can be enhanced through a preset video processing algorithm before video rendering, so that a target video stream is obtained.

For example, the process of playing video at a user terminal such as a mobile phone, a computer, etc. may include the following steps: after being preprocessed and coded, the video stream is transmitted to a user terminal through a network, and the user terminal decodes the received coded video stream to obtain the video stream to be rendered and played in a player of the user terminal.

In order to improve the visual effect of the rendered and played video, the video stream may be enhanced by a preset video processing algorithm before being rendered and played. The video processing algorithm may include any at least one available video processing algorithm, and may specifically be preset according to a requirement, which is not limited to the embodiment of the present disclosure.

For example, the enhancement processing may include, but is not limited to, sharpening, contrast adjustment, saturation adjustment, brightness adjustment, resizing scaling, denoising, flaw removal or compensation, and the like. Accordingly, the preset video processing algorithm may include, but is not limited to, a sharpening processing algorithm, a contrast adjusting algorithm, a saturation adjusting algorithm, a brightness adjusting algorithm, a resizing scaling processing algorithm, a denoising processing algorithm, a flaw removal or compensation processing algorithm, and the like.

In addition, specific values of video processing parameters in different video processing algorithms can be set according to video streams, so that different degrees of video processing can be performed on different video streams based on the quality of the video streams, and different enhancement processing can be realized.

The video processing parameters in different video processing algorithms are not completely the same, and specifically, the video processing parameters specifically included in the video processing algorithms may be set at the same time when the video processing algorithms are set, which does not limit the embodiment of the present disclosure.

For example, the video processing parameters in the contrast adjustment algorithm may include target contrast, contrast parameters, and the like; the video processing parameters of the saturation adjustment algorithm may include target packet saturation, etc.; the video processing parameters of the brightness adjustment algorithm may include target brightness, etc.; the video processing parameters of the resizing scaling algorithm may then include the target cropping size, the magnification scale, etc.

For example, for a sharpening algorithm, each original video frame in a video stream may be low-pass filtered, then subtracted from the original video frame to obtain a residual, and the residual is weighted and then added to the original video frame, assuming that the original input video frame is I and the low-pass filtering function is f_low-passThe weighting coefficient is a, then the sharpened video frame is I_sharp＝I+a(I-f_low-pass(I) ). The low-pass filter function and the weighting coefficient may affect a final sharpening effect, that is, a target sharpening effect, and therefore, in the disclosed embodiment, the low-pass filter function and the weighting coefficient may be used as video processing parameters of a sharpening processing algorithm, and further, the low-pass filter function and the weighting coefficient may be set according to a video stream.

For contrast adjustment algorithm, the contrast reduction function is assumed to be:

I_constrastwhere the pixel values of the input video frame are assumed to be at [0.0, 1.0 ], I-0.5 × β +0.5,0.0,1.0]Meanwhile, if the pixel value of the input video frame is at [0,255 ]]Then each pixel value may be divided by 255 as input to the above formula. The function clamp (x, a, B) is to set the value of input x larger than B as B, the value smaller than a as a, and β is the contrast parameter. The parameters β and the like therein may all affect the finally obtained contrast processing effect, that is, the target contrast effect, and therefore in the disclosed embodiment, the parameters β and the like may be used as video processing parameters of a contrast processing algorithm, and further the parameters β and the like may be set according to a video stream.

Of course, in the embodiment of the present disclosure, partial video processing parameters may also be set according to a video stream. For example, some video processing parameters may be set on demand or empirically, while other video processing parameters may be set on a video stream, and so forth.

For example, for the sharpening algorithm, a fixed low-pass filter function may be set empirically, and weighting coefficients may be set according to the video stream, and so on. For the contrast adjustment algorithm described above, the parameter β and the like may be set according to the video stream.

In step S13, the target video stream is rendered and played.

After the enhanced target video stream is obtained, the target video stream may be rendered and displayed. In the embodiment of the present disclosure, the target video stream may be rendered and presented in any available manner, and the embodiment of the present disclosure is not limited thereto.

For example, the target video stream may be rendered and presented by a video player of the user terminal, or a video player inside an application program, or the like.

In the disclosed embodiment, a video stream transmitted through a receiving network; enhancing the video stream through a preset video processing algorithm to obtain a target video stream; rendering and playing the target video stream; and when the video stream is subjected to enhancement processing through the video processing algorithm, the value of the video processing parameter in the video processing algorithm is obtained by setting according to the video stream. The quality of the video stream and the visual effect of the video picture are improved by performing self-adaptive enhancement processing on the video stream before rendering and playing.

Referring to fig. 2, in an embodiment of the present disclosure, the step S12 may further include:

step S121, performing content detection on the video stream, obtaining a target video processing method for processing the video stream from the video processing algorithm according to a content detection result, and determining a value of a video processing parameter of the target video processing method.

In addition, in the embodiment of the present disclosure, different adaptive enhancement adjustments may be performed on different video frames in a video stream by adaptively adjusting a post-processing algorithm and parameters according to different situations of the different video frames in the video stream. For example, if a certain video frame is dark, brightness of the certain video frame can be increased by a little intensity, or a certain video frame is fuzzy, and sharpening of a certain intensity can be performed on the certain video frame. Through self-adaptive adjustment, different videos can achieve a good subjective effect after being played.

At this time, content detection needs to be performed on the video stream, and then according to the content detection result, a target video processing method for processing the corresponding video stream is obtained from each preset video processing algorithm, and a specific value of a video processing parameter in each target video processing method is determined. Content detection is understood to mean detecting any specific content parameter in the video stream, such as brightness value, sharpness, contrast, size, noise value, etc., related to video quality, video visual effect, etc. Moreover, in the embodiments of the present disclosure, content detection may be performed on a video stream in any available manner, and the embodiments of the present disclosure are not limited thereto.

Moreover, when content detection is performed, content detection can be performed in units of video frames, and at this time, a content detection result of each video frame in the video stream can be obtained, so that a target video processing method for processing each video frame in the video stream can be obtained from a preset video processing algorithm according to the content detection result of each video frame, and a value of a video processing parameter of the target video processing method is determined.

And/or step S122, obtaining a target video processing method for processing the video stream from the video processing algorithm according to the light intensity of the environment where the video player corresponding to the video stream is located, and determining a value of a video processing parameter of the target video processing method;

in addition, in practical applications, the same video may be displayed and played in different environments, and in some special scenes, the display effect of the video may be affected. For example, video presentation may be affected in environments where the light is too dark or too bright. Therefore, in the embodiment of the present disclosure, a target video processing method for processing a video stream may be further obtained from a preset video processing algorithm according to the light intensity of the environment where the video player corresponding to the video stream is located, and a value of a video processing parameter of the corresponding target video processing method is determined, so as to adjust the video stream by automatic enhancement, and further adjust a picture of a rendered video, thereby achieving an optimal viewing experience.

The target video processing methods corresponding to different light intensities and the values of the video processing parameters in the target video processing methods can be preset according to requirements or experience, and the embodiment of the disclosure is not limited.

In addition, in the embodiment of the present disclosure, if the two manners described above are considered simultaneously to obtain the values of the target video processing method and the video processing parameters thereof, and if the same target video processing method is obtained for the same video frame for multiple times, the values of the video processing parameters in the same target video processing method for multiple times may be considered comprehensively, and the same target video processing methods for multiple times are combined into one time. The specific merging mode can be set by user according to the requirement, and the embodiment of the disclosure is not limited. Of course, in the embodiment of the present disclosure, the merging process may not be performed on the same target video processing method for multiple times, and the embodiment of the present disclosure is not limited thereto.

For example, for a video frame a in a video stream, it is assumed that the target video processing method obtained according to the content detection result thereof includes a brightness adjustment algorithm, and the video processing parameter includes a target brightness value of 100, and if the target video processing method for processing the video stream is obtained according to the light intensity of the environment where the video player corresponding to the video stream is located also includes a brightness adjustment algorithm, and the video processing parameter of the brightness adjustment algorithm includes a target brightness value of 80, then at this time, two corresponding brightness enhancement processes of the video frame a may be merged into one brightness enhancement process, and the target brightness value in the video processing parameter of the merged brightness adjustment algorithm may be 100 or 180, and so on. And assuming that the target video processing method obtained according to the content detection result does not include the brightness adjustment algorithm for the video frame B in the video stream, the video processing parameter of the corresponding brightness adjustment algorithm for the video frame B includes the target brightness value of 80, and so on.

And step S123, performing enhancement processing on the video stream according to the target video processing algorithm and the video processing parameters of the target video processing method to obtain a target video stream.

After the target video processing algorithm for adaptively adjusting the video stream is confirmed, the video stream can be enhanced correspondingly according to the target video processing algorithm and the video processing parameters of different target video processing methods, so as to obtain the target video stream. Specifically, the enhancement processing may be performed for each video frame in the video stream in units of video frames, so as to obtain the target video stream.

For example, for the video frame a and the video frame B described above, the video frame a may be subjected to luminance enhancement processing with a target luminance value of 100, while the video frame B may be subjected to luminance enhancement processing with a target luminance value of 80, and so on.

Optionally, in an embodiment of the present disclosure, the step S121 further includes:

step A1, according to the detection result of all the contents corresponding to the video stream, obtaining a target video processing method for uniformly processing the video stream from the video processing algorithm, and determining the value of the video processing parameter of the target video processing method.

Step A2, for each video frame in the video stream, according to the content detection result of the video frame, obtaining a target video processing method for processing the video frame from the video processing algorithm, and determining the value of the video processing parameter of the target video processing method.

After the content detection result of the video stream is obtained, a target video processing method of each video frame can be respectively obtained by taking the video frame as a unit according to the content detection result of each video frame, and the value of the video processing parameter of the target video processing method is determined. Or counting the overall quality index of the video stream according to the detection result of all the contents corresponding to the video stream, further acquiring a target video processing method for uniformly processing the video stream from a preset video processing algorithm, and determining the value of the video processing parameter of the target video processing method.

For example, if the overall brightness of the video stream is statistically dark or too bright according to the detection results of all the contents corresponding to the video stream, the brightness enhancement processing may be uniformly performed on each video frame in the video stream, and the corresponding brightness adjustment parameter is determined; or, when detecting that the noise in the decoded video stream is heavy according to the detection result of all the contents corresponding to the video stream, then performing a unified denoising process on the video stream, and setting corresponding denoising parameters, and the like.

Referring to fig. 2, in an embodiment of the present disclosure, the step S13 may further include:

step S131, when a definition adjusting instruction input by a user is received in the playing process of the target video stream, performing enhancement processing on the target video stream;

and step S132, rendering and playing the enhanced target video stream.

In addition, in the process of watching the video by the user, since the visual experiences and the visual requirements of different users are not completely consistent, and therefore, different users may have different requirements for the pictures played by rendering the same target video, in the embodiment of the present disclosure, in order to further improve the visual experience of the user watching the video and approach the visual requirements of the user, in the process of playing the target video stream by the video player, the video data that is not played by rendering currently in the target video stream may be further enhanced according to the definition adjustment instruction received from the user. The user may input the sharpness adjustment instruction in any available manner, which is not limited in the embodiment of the present invention. For example, the user may input different sharpness adjustment instructions through different preset gestures, or input different sharpness adjustment instructions through different language contents.

In addition, in the embodiment of the present disclosure, when the video stream is subjected to enhancement processing, because the video stream is already in the process of being displayed and a part of the video data is rendered and displayed in the process of this display, the enhancement processing performed on the video data that is rendered and played does not improve the visual experience of the user under the condition that the user does not look back, and therefore, only the video data that is not rendered and played currently in the video stream can be subjected to enhancement processing. Of course, if the user review is considered, the enhancement processing may be performed on all video streams, and the embodiment of the present disclosure is not limited thereto.

Therefore, enhancement processing can be always performed on the video data which is not rendered and played currently in the target video stream according to the latest received definition adjusting instruction, and then the video stream after the enhancement processing is rendered and played. Therefore, when the subsequent video data are continuously displayed according to the time sequence in the display process of the target video stream, the display effect of the subsequent video data can meet the current visual demand of the user.

In the embodiment of the present disclosure, the sharpness adjustment instruction may be input in any available manner, and the embodiment of the present disclosure is not limited thereto. Moreover, the primary sharpness adjustment instruction may control enhancement processing of the video stream by the at least one preset video processing algorithm, and may specifically perform custom setting according to requirements, which is not limited in the embodiment of the present disclosure.

Optionally, in an embodiment of the present disclosure, the step S131 further includes:

step B1, receiving gesture operation of a user in the playing process of the target video stream;

and step B2, executing a video processing algorithm to perform enhancement processing on the target video stream based on the gesture operation.

In the embodiment of the disclosure, the user can control the execution of the video processing algorithm through gesture operation to perform enhancement processing on the target video stream. Moreover, the user may input the gesture operation in any available manner, which is not limited to the embodiment of the present invention.

For example, a user can control a video processing algorithm to perform enhancement processing on the target video stream by using a special gesture on a screen of a user terminal while watching a video; or, the current limb movement of the user can be collected by the camera to be used as gesture operation; and so on. Alternatively, the gesture operation may be performed by a combination of one or more of the above manners, which does not limit the embodiment of the present disclosure. The corresponding relationship between the gesture motion and the video processing algorithm may be preset according to the requirement, and the embodiment of the present invention is not limited.
