Das, A and Biswal, A (2010) Development of Coding Schemes for Video. BTech thesis.
Video compression refers to the process of reducing the quantity of data used to represent digital video images, and is a combination of spatial image compression and temporal motion compensation. Spatial image compression is done by exploiting the spatial redundancy. Temporal motion compensation is done by exploiting the correlation of the pixels in the nearby frame.
In this thesis, investigations have been made to understand the actual mechanism of compression of still images and applying the principle to the video frames. Initially JPEG compression is analyzed and then it is used in MJPEG
compression. In later stages motion estimation techniques are analyzed so as to achieve compression by exploiting the temporal redundancy. Three algorithms for motion estimation are analyzed and compared with each other through their
