Hybrid binary image compression

چکیده
The redundancy in digital image representation can be classified into two categries: local and global. In this paper, we propose a new lossles binary image compression processing scheme which increases local redundancy for more compression efficiency. The algorithm consists of reordering rows and columns of image data for assembling data that has a same value: '0' or '1' merging each matrix element data which has a same value to reduce redundancy, encoding data to bitstream, then the encoded data will be compressed by other image compression algorithms. The experimental results confirm our technique performs better than other existing techniques.
