Abstract :
Several block matching motion estimation algorithms are discussed in order to determine the best techniques to use in very low bit-rate video coding (H.263 CODEC is used). Prediction error functions, search methods and simplified techniques are studied to determine the overall block matching strategy to use in the coding process of low movement sequences (head and shoulder sequences) and high movement sequences
