Master Topic : " Multiresolution Algorithm for Motion Estimation "
Our project of master proposes an algorithm of estimate of movement in the multi-resolution field. The concept of “Quadtree” is exploited in order to reduce the complexity of calculation of the motion estimation. Indeed, we highest will estimate the movement in the tape low frequency of the level of the decomposition of image. Then, we will deduce the motion vectors of the other tapes. Moreover, many techniques of improvement were integrated in order to optimize our algorithm. The evaluation of our algorithm proved these performances and its effectiveness while arriving at a good quality of estimate as well as an increase in the compression ratio.
