Sample-based video denoising

Abstract:

According to one implementation, a video processing system includes a computing platform having a hardware processor and a system memory storing a sample-based video denoising software code. The hardware processor executes the sample-based video denoising software code to receive a video sequence, and select a reference frame of the video sequence to denoise. For each pixel of the reference frame, the hardware processor executes the sample-based video denoising software code to map the pixel to a sample pixel in each of other frames of the video sequence, identify a first confidence value corresponding to each of the sample pixels based on the mapping, identify a second confidence value corresponding to each of the sample pixels based on the frame that includes the sample pixel, and denoise the pixel based on a weighted combination of the sample pixels determined using the first confidence values and the second confidence values.
