First Claim
Patent Images
1. A method, comprising:
- providing a first layer of an image, said first layer including features of said image having locations within said first layer;
providing a second layer of said image, said second layer including data blocks corresponding to and describing respective ones of said features, each said data block being in a location in said second layer at least substantially corresponding to a location in said first layer of the feature corresponding to each said data block; and
providing a third layer of said image, said third layer including pointers having locations in said third layer, each said pointer corresponding to a respective one of said features and a respective one of said data blocks, the location of each said pointer in said third layer at least substantially corresponding to the location in said first layer of the feature corresponding to each said pointer wherein said providing said second layer of said image comprises;
locating each said data block employing a packing algorithm to achieve a maximum proximity of each said data block to a target location for each said data block in said second layer, said target location in said second layer corresponding to the location in said first layer of the feature corresponding to each said data block.

Abstract
A system and method are disclosed which include providing a first layer of an image, the first layer including features of the image having locations within the first layer; and providing a second layer of the image, the second layer including data blocks corresponding to respective ones of the features; each data block being in a location in the second layer substantially corresponding to a location in the first layer of the feature corresponding to each data block, wherein a size and shape of the second layer substantially correspond to a size and shape of said first layer.
