Video Coding Based on Low Level Spatial Description of the Frames Sequence and on Human Visual System Perceptual Characteristics

Aim of this work is to envisage a video coding technique capable to exploit low level plots between nearby pixels inside the video sequence. The coding technique is first developed for images via the decomposition into small rectangular regions and then is extended to the video case utilizing a motion compensation technique to find replicas of the rectangles found on the first frame into the following ones. The results of these techniques are discussed in terms of obtained compression ratios and in terms of optimization of the results varying several parameters in the rules that lead to the composition of the shapes identified inside the video sequence.
