Abstract :
We improve the mathematical contents of two previous papers using the axioms of the basic logic over [0,1] due to Hajek (1998). We make use of the theory of fuzzy relation equations for getting lossy compression and decompression of images. These are understood as two-argument fuzzy matrices of sizes m×n, compressed to two argument fuzzy matrices of sizes h × k, h ⩽ m and k ⩽ n. We are widely inspired from two papers of Nobuhara et al. (2000), but we propose several slight modifications illustrating an algorithm implemented in Java
