Abstract: Data Compression is the process to eliminate redundancy between the neighboring pixel. To do this DCT is much more efficient. In this paper, an algorithm has been developed for DCT-V or ODCT-I using rectangular window. These updated DCT coefficient are independent of the Odd DST coefficient.
Keywords: DCT, DST, EDCT, ODCT.
