An image cropping system utilizes memory, an object detector, and an image cropper. A set of digital data that defines a graphical image is stored in the memory. The object detector analyzes the set of digital data and automatically identifies a portion of the digital data that defines an image of a particular object. The image cropper then uses the identified portion to determine a position of the object image within the graphical image. Based on the position of the object image within the graphical image, the image cropper automatically crops the digital data. In this regard, the position of the object image within the graphical image serves as a reference for determining which portions of the set of digital data should be cropped.

An automatic image cropping system is for use with a portable device having an image capture mechanism and a limited resource for storing or transmitting captured information. The system includes a region of interest suggestion engine defining plural image region candidates by performing image segmentation (20) on an image stored in digital form.
