Within this long list, the commands under the header “Morphological operations (binary images)” are the binary image operators useful in this homework set. One of these is bwmorph; type help bwmorph to see a list of the various operations which it provides. Note: if you try to do some operation on a variable named, say, im, and Matlab tells you that it’s illegal to do that operation on a variable of type uint8, then try it with double(im), which converts the variable im to type double. For all of the Matlab problems, give your Matlab commands as well as showing your numerical and image results. 1. Boundary extraction: Read the image eyechart into Matlab and look at it with the commands eye = imread(’eyechart.tif’,’tif’); imshow(eye) The array eye is of datatype uint8, so it is integer-valued, but the pixels take on only two
