Abstract :
In this work we propose to analyze the formal properties of the center/surround versions of Retinex. Our main goal is to clarify what the “best” surround should be. Two conditions are sound or necessary from an image theoretical viewpoint: scale invariance and integrability. Then, we present a new kernel, which finds an acceptable compromise between these two conditions. This new kernel is compared with different kernels obtained from some center-surround methods.
