Modified approximate 8-point multiplier less DCT like transform

Discrete Cosine Transform (DCT) is widely usedtransformation for compression in image and video\ud standardslike H.264 or MPEGv4, JPEG etc. Currently the new standarddeveloped Codec is Highly Efficient\ud Video Coding (HEVC) orH.265. With the help of the transformation matrix the computational cost can be\ud dynamically reduce. This paper proposesa novel approach of multiplier-less modified approximate DCT like\ud transformalgorithm and also comparison with exact DCT algorithm and theapproximate DCT like transform.\ud This proposed algorithm willhave lower computational complexity. Furthermore, the proposedalgorithm will be\ud modular in approach, and suitable for pipelinedVLSI implementation
