Image compression device, image compression method, image compression program, compression encoding method, compression encoding device, compression encoding program, decoding method, decoding device, and decoding program

摘要: There are provided an image compression device, method, and program, a code data encoding decoding program. The device includes: means for dividing the entire into blocks, calculating inclined plane or outer edge parameter specifying approximating respective blocks from block pixel values, error amount difference value to calculate between correction of each block; portion reversibly plane. includes synthesis judging change generation probability contained in be compressed obtained time series, generating including having large probability, synthesizing generated with compression/encoding data.
