|
This work presents a comparative analysis of fast motion compensation algorithms for vídeo compression, whitch aim at reducing the computacional complexity of the Full Search block matching tchnique. The first two ( LOG 2D and 3 Step) extremely reduce the complexity. However, they present the lowest performace. Two of them - Sucessive Elimination I ( ES I) and Adaptative Block Matching (AFB) - are schemes recently proposed in the literature. The last two algorithms (ES II and ES III) are modifications proposed in this thesis and are based on the ES I and AFB techniques. The algorithms are examined isolatedly an when operating in the MPEG environment.
