%% Detect Regions of Texture in Images % This example shows how to detect regions of texture in an image using the % texture filter functions %% % Read an image into the workspace and display it. In the figure, the % background is smooth--there is very little variation in the gray-level % values. In the foreground, the surface contours of the coins exhibit more % texture. In this image, foreground pixels have more variability and thus % higher range values. I = imread('eight.tif'); imshow(I) %% % Filter the image with the |rangefilt| function and display the results. % Range filtering makes the edges and contours of the coins visible. K = rangefilt(I); figure imshow(K)
