A New Lossless Image Compression Technique Based on Bose, Chandhuri and Hocquengham (BCH) Codes
A new binary (bit-level) lossless image compression method based on a well-known error correcting BCH codes has been introduced in this paper. The BCH encoder converts the message of k bits to a codeword of length n by adding 3 parity bits. In contrast the decoder eliminates these parity bits after verifying the received message; therefore, the proposed method utilizes this idea by dividing the image into blocks of size 7 bits. These blocks entered to the BCH decoder who eliminates the parity bits.
