Abstract:
1. A method for data compression by removing noise differences from successive frames in a video signal, the method comprising: accessing, by a processing unit, successive frames corresponding to a video signal, the successive frames including a current frame and a previous frame; determining whether a component of a given block in the current frame should be considered identical to the component of the corresponding given block in the previous frame by comparing respective representations of the components of the blocks in the frequency domain; and causing the component of the given block in the current frame to be identical to the component of the corresponding given block in the previous frame where it is determined that the component of the given block should be considered identical to the component of the corresponding given block in the previous frame, wherein determining whether the component of the given block in the current frame should be considered identical to the component of the corresponding given block in the previous frame comprises accessing respective frequency domain results matrices for the component in the current frame and the previous frame, and determining that the component of the given block in the current frame should be considered identical to the component of the corresponding given block in the previous frame where a plurality of the values in the first row and a plurality of the values in the first column in the respective frequency results matrices are equal as between the current frame and the previous frame.
