Paper Abstract

As images are increasingly used in wireless communication, such as mobile phones and PDAs, it is important to reduce the energy consumption for transmitting and receiving images. The energy is approximately proportional to the sizes (numbers of bytes) of the images. Many existing techniques aim to improve compression ratios while preserving the image fidelity without perceivable differences. In this paper, we propose a new approach by allowing visible distortion in the images. Our method eliminates or reduces the fine details (textures) so that new images have smaller file sizes and require less energy to transmit or receive. Even though new images may be visually different, the essential information is preserved. Our experiment uses 400 images and achieves up to 40.1% and average 32.2% reduction in file sizes.
