MATLAB: How to select the appropriate dilation parameter

dilationImage Processing Toolbox

I have a true oolor image. I want to dilate the image for further processing it. There are different types of dilation parameters like disc,line,diamond etc.. I do not know which is the appropriate one and also what value to give as radius/length etc for my image. Can anyone suggest ???

Trial and error. When it's best for you, you'll know it. There is no one overall universal answer to that question, like "disk of radius 11", that applies to every color image ever generated on the planet (or off the planet).

You have to get 2 binary images. Each one containing only the circles of less than, or greater than 100 pixels. See my Image Segmentation Tutorial where I extract out coins of different diameters using find() and ismember(). http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 Let me know if you can't adapt it. If that is the case, attach your image and your best attempt at adapting the code.

Then call imdilate() on each image.

se1 = strlen('disk', 20)
dilated1 = imdilate(binaryImage1, se1);
se2 = strlen('disk', 10)
dilated2 = imdilate(binaryImage2, se2);

Use imregtform to perform the registration on the blurred images and to obtain the optimal tform. Then apply the tform to your original unblurred moving image.
