Abstract:
Importance of compression in the field of digital image processing is growing due to the increasing amount and resolution of images. Research on lossy image compression based on partial differential equations (PDEs) is still a subject of ongoing research. One way of determining efficiency of a lossy compression method is to quantify the reconstruction error between the original image and the reconstructed image. The image quality can be evaluated objectively and subjectively. Our experiments using different image quality assessment methods demonstrate that for high compression rates, PDE-based approach does not only give far better results than the widely-used JPEG standard, but can even beat the quality of the highly optimised JPEG 2000 codec.
