Summary: The purpose of this work is to analyse what happens to the surface information when the image resolution is modified. We deduce how the surface texture appears if seen from different distances. Using Colour Photometric Stereo a method for predicting how surface texture looks like when changing the distance of the camera is presented. We use this technique on the recognition of textures seen from different distances.
Real sets of images have been used in order to evaluate the performance of the recognition system.
