Comparative Study between DCT and WaveletTransform Based Image Compression Algorithm

Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 1

Abstract

 Abstract: Discrete cosine transform emerged as a popular mathematical tool in past decade and widely used inimage compression algorithm due to its high energy compaction capacity. But this energy compaction has somelimitation in blocking artifacts that overcome by another mathematical tool wavelet transform basedcompression which have both frequency and spatial component study at same time. In this paper we study acomparison between DCT based image compression and wavelet based image compression using CDF9/7wavelet as used in JPEG-2000 Standards based on common encoding scheme known as Huffman encoding forboth. We also analyzed a trend based on different level of wavelet transform on image size and image qualitybased on mean square error.
