You can use MATLAB. The Image Processing Toolbox would also be helpful, as would this discussion: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer.

Evidently you haven't read that link yet, or just ignored it. For example you would have uploaded an image, or showed some code, or both. And I don't think you've read this link either http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers. As it is, about all I can say is to use imcrop().
