Motion Estimation

These functions calculate:

residual block - difference between source block and predicted block (Table “Evaluation of Residual Blocks”) some characteristics of the residual block (Table “Evaluation of Residual Block Characteristics”) some characteristics of the blocks. These characteristics can be used for comparison of the blocks. (Table Table “Evaluation of Block Characteristics”).

The use of some functions described in this section is demonstrated in Intel® IPP Samples downloadable from http://www.intel.com/cd/software/products/asmo-na/eng/220046.htm .
