Video segmentation is performed at the first stage of video compression. At this stage, the video is split into frames according to the value of M. M- specifies the number of frames

The standard median filter is a simple rank selection filter that attempts to remove impulse noise by changing the luminance value of the center pixel of the filtering window with

The gradient criterion based fusion in Dual Tree Complex Wavelet domain has been performed using various images from a standard image database or real time
