Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
A method of describing a boundary of a region in an image, comprising the steps of: (a) providing an N×M pixel image containing a region; (b) covering said region with an m×n array of k×k blocks of pixels, k at least 2; (c) labelling each of said k×k blocks as in said region when at least tk 2 pixels of said k×k block are in said region, said multiplier t is a positive number between 0 and 1; and (d) describing the boundary of said region by said labelling of said k×k blocks, wherein the boundary is a complete boundary of the region.
Claim 2
Independent Claim
103 words
A method of describing a boundary of a region in an image, comprising the steps of: (a) providing an N×M pixel image containing a region; (b) covering said region with an m×n array of k×k blocks of pixels, k at least 2; (c) labelling each of said k×k blocks as in said region when at least tk 2 pixels of said k×k block are in said region, said multiplier t is a positive number between 0 and 1; and (d) describing the boundary of said region by said labelling of said k×k blocks, wherein the boundary is a complete boundary of the region.
