Jayavrinda Vrindavanam V, Saravanan Chandran, Gautam Kumar Mahanti · International Conference & Workshop on Emerging Trends in Technology · 2012
ABSTRACT The paper attempts a comparison between JPEG and JPEG2000 –wavelet- based image compression based on the output from different images. Also the PSNR values are compared for different images. The paper also reviews the recent advancements in this area after the introduction of JPEG2000 so as to bring out the further research prospects in the field of image compression. General Terms Image compression, Huffman coding, low bit rate transmission, JPEG, JPEG 2000, wavelet, PSNR Keywords JPEG, JPEG2000, image compression, wavelet, DCT, 1. INTRODUCTION Image compression is an established and well researched segment which has been undergoing significant advances over the period of time. Keeping in view the on-going advancements taking place in this field, the paper focuses on the recent advances in this field starting with the two latest image compression standards, such as JPEG and JPEG2000 the distinguishing feature of JPEG2000 being wavelet based image compression. After comparing the theoretical differences vis-a-vis the experimental results of these key standards, the paper also details some of the recent studies in the field of wavelet based image compression.
