Abstract
A method for auto-cropping includes, creating a saliency map corresponding to a digital image, the saliency map indicating a relevance of pixels within the digital image with saliency values within a number range, a lower end of the number range being less than zero and an upper end of the number range being greater than zero. The method further includes, analyzing the saliency map to find a potential cropping rectangle, the potential cropping rectangle having a maximum sum of saliency values within borders of the rectangle.
