It should be noted that the video call data is composed of a frame of picture and corresponding sound, that is, the original video call data is composed of sound and a frame of picture, and one frame of picture is a picture, so that other pictures before the silhouette of the first user portrait in each call picture corresponding to the original video call data are shielded, and the video call data without the first user background picture can be obtained, that is, the first video call data is obtained. Specifically, referring to fig. 6 and 7, fig. 6 is a call screen before the other screen outside the outline of the first user portrait is masked, and fig. 7 is a call screen obtained after the other screen outside the outline of the first user portrait in the call screen of fig. 6 is masked.
Further, step S20 includes:
step a, identifying the portrait outline of a first user corresponding to the first terminal in each call picture corresponding to the original video call data through a portrait identification technology.
Specifically, after the first terminal collects original video call data, the first terminal identifies a portrait outline of a first user in each call picture corresponding to the original video call data through a portrait identification technology. The portrait recognition technology belongs to the biological characteristic recognition technology, which is used for distinguishing organism individuals from the biological characteristics of organisms (generally, specially, people).
And b, deleting other pictures except the portrait outline in each call picture, and screening the other pictures except the portrait outline of the first user in the call pictures to obtain first video call data.
When the first terminal identifies the first user portrait outline in each conversation picture, the first terminal deletes other pictures except the first user portrait outline in each conversation picture to shield the other pictures except the first user portrait outline in each conversation picture, so that video conversation data after picture processing is obtained, and the video conversation data after picture processing is recorded as first video conversation data.
Further, the first terminal can also identify the portrait outline of the first user in each call picture corresponding to the original video call data through a deep learning algorithm. The deep learning algorithm includes, but is not limited to, LSTM (Long Short-Term Memory) and RNN (Recurrent Neural Network). Specifically, the first terminal can obtain a certain number of images containing the portrait, train the images through a deep learning algorithm to obtain a deep learning model capable of identifying the portrait outline in the images, and then input the collected original video call data into the trained deep learning model to identify the portrait outline in each picture in the original video call data.
Step S30, the first video call data is sent to the second terminal, so that a second user of the second terminal can carry out video call with the first user through the first video call data.
And after the first terminal obtains the first video call data, the first terminal sends the first video call data to the second terminal. And after the second terminal receives the first video call data, the second terminal outputs the first video call data in a screen of the second terminal so that the second user can conveniently carry out video call with the first user through the first video call data. It should be noted that, in the screen of the first terminal, the first video call data may be set to be displayed, or the original video call data may be displayed. When the first terminal screen is set to display the first video call data, the first user sees that the own video picture in the first terminal screen does not have the background picture of the position where the first user is located, and at the moment, the background seen by the first user in the video picture can be a white canvas preset by the first terminal; when the first terminal screen is set to display original video call data, a video picture seen by the first user in the first terminal screen is a background picture with the current position of the first user.
In the embodiment, after a call instruction of video call with a second terminal is detected by a first terminal, video call data corresponding to a first user is acquired through a camera of the first terminal, and other pictures outside the face outline of the first user in the video call data are shielded, so that only a character image of the first user exists in each frame of picture corresponding to the video call data, processed video call data are obtained, and the processed video call data are sent to the second terminal, so that a second user of the second terminal can carry out video call with the first user through the processed video call data.
Further, a second embodiment of the method for optimizing video call data of the present invention is provided. The second embodiment of the method for optimizing video call data is different from the first embodiment of the method for optimizing video call data in that the step S20 further includes:
and c, shielding other pictures except the figure outline of the first user in each call picture corresponding to the original video call data, and acquiring a pre-stored virtual background.
And d, setting the virtual background as a background picture of the call picture to obtain first video call data.
When the first terminal shields other pictures except the portrait outline of the first user in each call picture corresponding to the original video call data, the first terminal acquires a virtual background stored in advance. The virtual background can be set by the first user according to specific needs, and specifically, the virtual background can be videos, pictures, slides and the like. After the first terminal obtains the virtual background, the first terminal sets the virtual background as a background picture of each call picture to obtain first video data. If the virtual background is a landscape image, the second user can see through the first video call data, and the landscape corresponding to the landscape image is behind the first user.
Further, if the virtual background is not preset by the first user, and a default background picture is set in the first terminal, the first terminal acquires the default background picture after shielding other pictures except the portrait outline of the first user in each call picture corresponding to the original video call data, and sets the default background picture as the background picture of each call picture.
In the embodiment, after other pictures except the first portrait outline in each call picture corresponding to the original video call data are shielded, the first terminal sets the pre-stored virtual background as the background picture of the call picture to obtain the first video call data, so that the first user can set the background picture in the video call process according to the preference in the video call data sent to the second user, and the interestingness of the video call is improved.
Further, a third embodiment of the method for optimizing video call data of the present invention is provided. The third embodiment of the method for optimizing video call data is different from the first or second embodiment of the method for optimizing video call data in that, referring to fig. 4, the method for optimizing video call data further includes:
and S40, identifying the sound data belonging to the first user in the first video call data.
After the first terminal obtains the first video call data, the first terminal identifies sound data belonging to the first user in the first video call data. Specifically, the first terminal may store voiceprint information of the first user in advance, and then the first terminal identifies, according to the stored voiceprint information of the first user, voice data belonging to the first user in the first video call data by using a voiceprint identification technology. Further, the first terminal may also store voiceprint information of multiple users, for example, voiceprint information of the first user and a parent of the first user, at which time, when the first terminal identifies the voice data in the first video call data through a voiceprint identification technology, the first terminal may identify the voice data of the multiple users.
Further, step S40 includes:
and e, determining sound data with the highest decibel in the first video call data.
And f, determining the sound data with the highest decibels as the sound data belonging to the first user in the first video call data.
Further, in the process that the first terminal collects the original video call data corresponding to the first user through the camera, the first terminal can collect the sound data through the earphone of the first terminal, and it can be understood that the collected sound data is the sound data in the original video call data. After the first terminal obtains the first video call data, the first terminal determines sound data with the highest decibel from the first video call data, and determines the sound data with the highest decibel as sound data belonging to a first user in the first video call data. It will be appreciated that during a video call between a first user and a second user, there is other noise in the video call data in addition to the voice data of the first user.
And S50, deleting other voice data except the voice data of the first user in the first video call data to obtain second video call data.
And when other sound data except the first user sound data in the first video call data are determined, the first terminal deletes the other sound data except the first user sound data in the first video call data to obtain the first video call data after sound processing. In the embodiment of the present invention, for convenience of distinguishing, the first video call data after the sound processing is recorded as the second video call data.
The step S30 includes:
step S31, sending the second video call data to the second terminal, so that a second user of the second terminal can carry out video call with the first user through the second video call data.
And after the second video call data is obtained, the first terminal sends the second video call data to the second terminal so that a second user of the second terminal can carry out video call with the first user through the second video call data.
It should be noted that, in the embodiment of the present invention, the original video call data is subjected to the picture processing first and then the sound processing is performed, and in other embodiments, the original video call data may be subjected to the sound processing first and then the picture processing is performed.
In the embodiment, the optimized video call data is obtained by identifying the sound data belonging to the first user in the first video call data and then deleting the sound data except the sound data of the first user in the first video call data, so that the video call data sent to the second user is prevented from carrying other noises except the sound data of the first user, and the video call quality of the first user and the second user in the video call process is improved.
Further, in order to increase the interest of the video call, step S50 includes:
and g, deleting other sound data except the first user sound data in the first video call data, and acquiring pre-stored virtual sound.
And h, setting the virtual sound as the background sound of the first video call data to obtain second video call data.
Further, when the first terminal deletes the sound data of the first video call data except the sound data of the first user, the first terminal obtains the virtual sound pre-stored in the database thereof, wherein the virtual sound can be set by the first user according to specific needs, and the virtual sound includes but is not limited to music and sound segments recorded by the first user dashed lines. After the first terminal acquires the pre-stored virtual sound, the first terminal sets the virtual sound as the background sound of the first video call data to obtain second video call data. It is understood that the background sound may be heard by the second user during the video call with the first user through the second video call data.
Further, in order to ensure the call quality of the video call, in the process of outputting the second video call data, the second terminal may set the output volume of the background sound, so that the output volume of the background sound is smaller than the output volume of the sound data of the first user to a certain extent, and a difference between the output volume of the background sound and the output volume of the sound data of the first user may be set according to specific needs, and in this embodiment, the difference is not specifically limited.
Further, a fourth embodiment of the method for optimizing video call data of the present invention is provided. The fourth embodiment of the method for optimizing video call data is different from the first, second, or third embodiment of the method for optimizing video call data in that, referring to fig. 5, the method for optimizing video call data further includes:
step S60, encoding the first video call data to obtain the encoded first video call data.
After the first terminal obtains the first video call data, the first terminal encodes the first video call data to obtain encoded first video call data. The encoding algorithm for encoding the first video call data includes, but is not limited to, MPEG (Moving Picture Experts Group), h.261, h.263, h.264, and the like.
The step S30 further includes:
step S32, sending the encoded first video call data to the second terminal, so that a second user of the second terminal can perform video call with the first user through the first video call data.
And after the first terminal obtains the coded first video call data, the first terminal sends the coded first video call data to the second terminal. When the second terminal receives the encoded first video call data sent by the first terminal, the second terminal decodes the encoded first video call data to obtain the uncoded original first video call data, and outputs the decoded first video call data in a screen of the second terminal, so that the second user can carry out video call with the first user through the first video call data. It should be noted that, an encoding algorithm for the first terminal to encode the first video call data is negotiated with the second terminal in advance, and a decoding algorithm adopted by the second terminal is corresponding to the encoding algorithm adopted by the first terminal, for example, the first terminal encodes the first video call data by using the h.264 algorithm, and at this time, the second terminal also correspondingly decodes the first video call data by using the h.264 algorithm.
It should be noted that, before the first terminal sends the second video call data to the second terminal, the first terminal may also encode the second video call data.
In the embodiment, before the first terminal sends the video call data to the second terminal, the first terminal encodes the video call data to be sent to the second terminal, and sends the encoded video call data to the second terminal, so that the transmission rates of the video code streams of the first terminal and the second terminal are improved through an encoding technology.

and i, detecting whether the first terminal starts a video call data optimization function.
And j, if the first terminal starts the video call data optimization function, executing the step of shielding other pictures except the portrait outline of the first user in all call pictures corresponding to the original video call data to obtain first video call data.
Further, after the first terminal acquires original video call data corresponding to the first user in the video call process through the camera of the first terminal, the first terminal detects whether the video call data optimization function is started. And if the first terminal starts the video call data optimization function, the first terminal shields other pictures except the portrait outline of the first user in each call picture corresponding to the original video call data to obtain the first video call data. Further, if the first terminal does not start the video call data optimization function, the first terminal directly sends the acquired original video call data to the second terminal. Specifically, if the first terminal detects that the state identifier of the video call data optimization function is the start identifier, the first terminal determines that the video call data optimization function is started; if the first terminal detects that the state identifier of the video call data optimization function is the closing identifier, the first terminal determines that the video call data optimization function is not opened and is in a closing state. In the embodiment of the present invention, the expressions of the on flag and the off flag are not limited, for example, the on flag may be set to "11", and the off flag may be set to "00".
