Automatic image cropping for mobile device with built-in camera

The automatic image cropping scheme proposed in this paper can be used in a low-resource camera device, such as mobile phone or PDA equipped with a camera, to identify the region of interest (ROI) from a captured image, and only save the user desired region/block in order to save memory resources on the device. The algorithm is designed for color images and the ROI suggestion engine is based on entropy, therefore provides intelligence that is closer to human perception when capturing an object in the viewing area, yet it is simple to implement with less computational intensity on a low resource device.
