Abstract
A method for coding an image including calculating, feature parameters which characterize an input block (range block) to be coded and a search block (domain block) in a reference image frame. These feature parameters can also be calculated and held in advance. The feature parameters are compared to seek a search block whose similarity to the input block is highest. A search process for seeking a similar block, i.e., a search process for seeking a motion vector or an affine transformation parameter, can easily and quickly be carried out simply by comparing the feature parameters without repeating square error calculations.
