MATLAB code and Binary Image database

From: Mohi on 25 Jun 2010 12:39 I would like to inform you that I need a MATLAB source code to recognize different regular geometric shapes such as: squares,rectangles,triangles,circles and ellipses in different sizes using neural network. All of the images containing these shapes should be in binary format with the size of 300*400 pixels. Would you please give me a MATLAB code to detect these geometric shapes? Furthermore, I need a binary image database for 2D geometric shapes. Would you please, give me a link to download such a database?

Sorry, I don't know of such a function or such a database. I guess you'll just have to create your own function and database. If you encounter problems while creating your function, show the group what you've done and ask a SPECIFIC question about where you're stuck and you may receive some help. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com

Or you can take a look at this old link for a list of some image databases: http://www.cs.cmu.edu/~cil/v-images.html
