I am not an expert on the related image manipulation field. But I wonder whether you can refer to some professional image manipulation plug-ins for help? Especially for those which can be totally manual, it is said that they allow users to redevelop the features according to our own favors. You can google it and select one whose way of processing is simple and fast to help you with the related work. Remember to check its free trial package first if possible. I hope you success. Good luck.
