Dear sirs, Hi, I would like to inform you that I want to perform a project using MLP neural network to recognize binary images containing three types of geometric shapes such as squares,rectangels and circles. Furthermore,each image includes only one geometric type. The output of network would be: '1' if the network detects square shape. '2' if the network detects rectangle shape. '3' if the network detects circle shape. '4' if none of these shapes detected. Would you please send me a matlab source code for this project? Your prompt reply would be so appreciated. regards,
