Matlab & Image Processing

Hello, I need some basic image processing and object detection (balls on a table at an angle). I have a basic script but i need you to tweak the code to make it more robust. You can use the image processing toolbox. I will send you the images and the script I already have. Please send me examples of previous works you have done. I will pay max $30,- as this is a very simple project that shouldn't take much time, I just don't have the resources right now.. There are many similar small projects to come though for the right person. Happy Bidding PS: please start your bid with "matlab/image".
