Real-time video denoising method and terminal during coding, and non-volatile computer readable storage medium

An electronic device for video denoising, comprising:

• one or more processors and memory including instructions, the instructions, when executed by the one or more processors, cause the processors to perform operations comprising:
• receiving an image stream comprising a sequence of image frames from a video source;
• and
• while continuing to receive the video stream from the video source, performing multi-stage denoising processing on a respective frame of the sequence of images frames in the video stream, including:
• detecting a change in a current network status of a network connection between the electronic device and a remote destination device for the image stream, the change in the current network status includes a change in a bandwidth of the network connection;
• and
• in response to detecting the change in the current network status of the network connection between the electronic device and the remote destination device for the image stream:
• adjusting a current value for a predefine flatness threshold for detecting a flat area within the respective frame of the image stream in accordance with the change in the current network status of the network connection;
• identifying one or more flat areas within the respective image frame in accordance with the predefined flatness threshold that has been adjusted in accordance with the change in the current network status of the network connection;
• and
• performing, using a predefined filter, denoising processing on the one or more flat areas that have been identified in accordance with the predefined flatness threshold that has been adjusted in accordance with the change in the network status of the network connection.
