A methodology for displaying a website on a hand held display device (HHDD) is disclosed. The present invention comprises an Image Modification Program (IMP) and a Navigation Program (NP). The IMP analyzes the webpage HTML to determine if an image is present and if the image exceeds the allotted image display space on the HHDD display screen. The IMP calculates the required number of x-axis and y-axis divisions and fragments the image accordingly. The IMP displays the reduced web page on the HHDD, but replaces the reduced image with a fragment from the fragmented image. The fragment is displayed at the intended resolution allowing the user to view a portion of the image at full size, as opposed to the whole image at a reduced size. The NP of the present invention allows the user to move from one fragment to another. An alternative embodiment utilizing a proxy is also disclosed.

An image segmentation system selects candidate images from an image collection. Image analysis on individual images proceeds by first detecting salient features on each image. Patches are centered on points of interest located on the salient features of the image. Each patch is gridded into blocks. The block feature vectors are merged to generate a patch feature vector. A fingerprint for each image is obtained by merging patch feature vectors across the image. Images with similar fingerprints are identified and geometric matching is performed to further select images with similar objects. Common regions are tabulated and merged into single regions to segment out coherent objects.
