摘要： The invention relates to a method for generating from a sequence of at least one source image, called source sequence, a sequence of at least one reduced image, called reduced sequence, the at least one reduced image having a size smaller or equal to the size of the at least one source image. The at least one reduced image is generated by extracting from the at least one source image at least one image part whose size and position depend on the perceptual interest of the pixels comprised in the at least one image part.
