The invention discloses a video denoising
processing method and device based on a fixed scene. The method includes the steps of obtaining a frame of video data, extracting key
component video data in the frame of the video data, performing downsampling
processing on the key
component video data, performing background modeling on the downsampled key
component video data so as to extract a foreground region and a background region, estimating a
current noise power value of the background region according to the difference value of the current pixel value of the background region and the pixel value of a prior background region, performing no denoising
processing on the key component video data if the
noise power value is less than a preset denoising processing judgment threshold, and performing denoisng processing on the foreground region and the background region of the key component video data if the
noise power value is larger than the preset denoising processing judgment threshold. According to the video denoising processing method and device, the
subjective quality of videos can be improved, calculation amount and storage resources are low, and hardware implementation is easy.
