Some gray-level manipulation techniques are described, the first of which involves changing the gray-level distribution within the picture. Thereafter a method for extracting relatively noise-free objects from a noisy background is described. The purpose of these techniques is to preprocess a textural scene for subsequent analysis or classification. The present state of the art of texture analysis in general does not enable the parameters associated with the techniques to be generalized. Results for a range of parameters for both real and computer-generated pictures are therefore given.
