Image compression is an active area of research with a wide range of applications. Being able to represent an image with lesser number of coefficients, without affecting the image quality has been the prime aim of image compression. In this research, a new image compression technique has been proposed, based on Slantlet Transform and the principle of Phase Congruency. The compressed image quality has been assessed by computing the PSNR values and the compression ratios. Experimentation show highly promising results, in terms of the level of compression and the quality of the fused image.
