Abstract
We propose a method for devising approximate
multiplication-free algorithms for compressed-domain linear operations
on images, e.g., downsampling, translation, filtering, etc.
We demonstrate that the approximate algorithms give output images
that are perceptually nearly equivalent to those of the exact
processing, while the computational complexity is significantly
reduced.
