Abstract
A new technique able to improve the performance of the standard DCT compression algorithm in terms of compression size, maintaining almost constant the perceived quality is presented. The measured improvement is obtained profiling the relative DCT error inside typical image pipeline of data acquired by digital sensors. Experimental results show the effectiveness of the methodology proposed, validated also by using two perceptual quality metrics.
