Medical Image Compression Using ISPIHT & Modified JPEG2000 Hybrid

Yashpreet Sain, Sourav Garg

Abstract: Compression means reducing the number of bits required to represent the data. Compression plays a crucial role in the field of image processing. The images produced using various digital techniques are required to be compressed in accordance with the area of application. Digital imaging is an integral part of the field of medicine. A large amount of medical images are produced every day and the number is on the rise. Medical images also need to be compressed so that they do not consume up large amount of valuable resources like storage drives and network bandwidth as well. This paper presents a hybrid compression method developed by improving and combining two existing compression techniques viz. SPIHT and JPEG2000. The compressed images are evaluated on the basis of various quality matrices which are PSNR, MSE and entropy.

Keywords: Image compression, lossless compression, medical images, ISPIHT, JPEG2000, PSNR, MSE, Entropy
