Abstract
Methods and apparatus for encoding and decoding image data based on one or more parameters. In one embodiment, various spatial portions or regions of image data (e.g., a still or moving image) are weighted according to the perceived or measured quality. Processing for these weighted regions can be selectively altered or adjusted so as to optimize one or more operational parameters including for example processing and/or memory requirements, or speed.
