Abstract
When we perform a visual analysis of a cosmic object photograph, the contrast plays a fundamental role. We present an approach based on spatial color algorithms to enhance local contrast to make it easier to detect relevant information. We show very promising results on amateur photographs of deep sky objects. The results are presented for a qualitative and subjective visual evaluation and for a quantitative evaluation through image quality measures.
