| description | Systems, methods, and instrumentalities are disclosed for denoising high dynamic range video using a temporal filter. A frame of an uncompressed video stream may be received. The frame may include a plurality of pixels. It may be determined that a chroma component of a pixel of the plurality of pixels belongs to a predefined region. The region may be predefined on the basis of one or more chroma components. The predefined region may be a CbCr space. The chroma component of the pixel may be compared with a chroma component of a co-located pixel to determine if the chroma component of the co-located pixel belongs to the predefined region. The pixel may be filtered using a denoising filter. The denoising filter may be a temporal filter. The denoising filter may be a Crawford filter. The uncompressed video stream including the filtered pixel may be encoded. |
