Abstract
The invention relates to a method for the compression of a raster type image material by using segmentation, such that: a widespread start image (1) is divided into segments (1A, 1B, 1C, 1D), such that the segments contain distinct image sections different from each other at least in terms of color qualities thereof, and each segment is compressed with an image compression algorithm chosen according to internal qualities of the segment or with a different set of parameters for the image compression algorithm, coordinates for each segment portion are stored in a memory, and compressed segments (A, B, C, D) and coordinates (XA, XB, XC, XD) therefore are processed for a compression result R.

A method for the compression of a raster type image material by using segmentation, said method comprising the steps of:
- dividing a widespread start image material (1) into segments (1A, 1B, 1C, 1D), such that the segments contain distinct image sections different from each other at least in terms of color qualities thereof;
- compressing each segment with an image compression algorithm chosen according to internal qualities of the segment, or with a different set of parameters for the image compression algorithm;
- storing coordinates for each segment portion in a memory;
- and
- processing compressed segments (A, B, C, D) and coordinates (XA, ZB, XC, XD) therefor for a compression result (R), wherein the result (R) is processed for a www-page imaging code, and the compressed segments (A, B, C, D) cited thereby are discrete compressed image files.
