Abstract :
In the present communication an approach to the performance optimization of an H.261 implementation is described. Discrete Cosine Transform (DCT) coefficient pruning is employed and its effect on motion estimation strategies is studied. This interplay produces some very interesting experimental results on the trade-off between quality and speed of video coding
