meshCanopy 1.0

This function makes it easy to display a mesh directly above a grayscale image. The mesh can use any colormap and can be at variable heights above the image. The example, which requires the IPT, is the screenshot.help meshCanopy function meshCanopy: display a mesh above a grayscale image SCd 11/18/2010 Updates: -11/22/2010: Added example (requires IPT) Added height input argument Input Arguments: -I: 2-dimensional grayscale image slice. The values are expected to range from 0 to 255. If the maximum value is greater than 255 or the minimum value is less than 0, it will be scaled to 0:255. Else it will remain unchanged. -Mdata: 2-dimensional mesh data (Z for a meshplot). NOTE: the mesh command will be called with: >>[ii jj] = meshgrid(ceil(cumsum(diff([0 linspace(1,size(I,2),size(Mdata,2))]))),ceil(cumsum(diff([0 linspace(1,size(I,1),size(Mdata,1))])))); >>mesh(ii,jj,Mdata); and thus does not need to be the same size as the image! -Mmap: string, function_handle or nx3, mesh color map. See: >>doc colormap for valid options. The argument is optional and defaults to 'jet' Examples: 'jet', @jet, [0 0 1; 0.5 0;.1 .1 .1] -height: scalar height of the mesh above the image so you can see both. Optional defaults to 80. Output Arguments: -None! Example: (Requires the Image Processing Toolbox) %Display a Mesh Canopy of a standard deviation image, above the original image I = imread('cameraman.tif'); M = stdfilt(I); meshCanopy(I,M,@spring) See also: mesh colormap
