Abstract:
A method for compressing an image, comprising:dividing the image into image segments, the image segments including at least one segment of a first type and at least one segment of a second type, wherein at least each at least one segment of the first type is divided into image blocks and compressed on a block-by-block basis, and at least one of the image blocks of the at least one segment of the first type contains a boundary between data of the first type and missing data, each image block comprising a plurality of pixels, and each pixel having a value;identifying each image block containing a boundary with missing data;recursively replacing the missing data of each first type boundary block with first type data by assigning the value of a closest boundary pixel;compressing each first type image block and each first type boundary block using a first compression technique; andcompressing each at least one segment of the second type using a second compression technique.
