Information is generated at very high speed in today's Digital Era. Images have vast share in Information generated, so it's important to reduce the image file size for storage and effective communication. Image compression technique helps in reducing storage and bandwidth requirement for transmission. Optimization of Image compression algorithms is the basic crux of this paper. DCT is most popularly used lossy image compression technique. It has disadvantage that at higher compression ratiodoi:10.18535/ijecs/v6i6.18 fatcat:3fas7isfb5bpvapxdl4iqc72le
