METHOD AND FORMAT OF RECORD FOR IMAGE COMPRESSION

摘要

FIELD: physics, processing of images. ^ SUBSTANCE: invention deals with method and format of record envisaging run-length compression of image segment data. The proposed method of image segment data processing envisages image segment object assignment, object binary bitmapping and investigation into the binary bitmap bit composition with a view of finding out whether the number of first binary value bits exceeds that of second binary value ones, the process including operations aimed at estimate of the necessity to have the binary bitmap converted in such a way that the number of first binary value bits with the converted binary bitmap be less than that of second binary value ones, and specification of the compression principle based on identification of the two most significant bits within the serial bit area of the binary bitmap or the converted binary bitmap. ^ EFFECT: enhanced efficiency of image segment data compression and provision for appropriate ratio and/or flexibility of compression of the mentioned segments as per their content indicators. ^ 37 cl, 31 dwg
