Surface Image Local Contrast Enhancement Based on Texture Discrimination via Grey Relational Analysis
Based on the analysis of main texture information in the neighborhood of image, we use the grey relational coefficient to decide the most obvious texture direction, which is conductive to selectively increase the local contrast of surface image. Simulation results show that the algorithm can obtain better experimental results, and it is a good method worth continuing to study later.
