Abstract: In basic Block Truncation Coding, the given data sequence is encoded into a two level quantized approximation. This results in two segments one of which is comprised of the high level value and the other one, the low level value. In the proposed scheme, the basic Block Truncation Coding is refined by further sub segmenting the present segments. This increases the granularity of the data and reduces the truncation error.
Keywords: Two stage Block Truncation Coding, Binarization.

Scope of the Article: Network Coding
