Abstract
A method of shape detection detects a figure with a contouring loop method that extracts at least one iso-contour polygon from a set of pixels in an image using a triangular lattice superimposed over the set of pixels of the image. Then starting from an original triangle, the iso-contour polygon is extracted by selecting an intensity chroma value within the set of pixels between three corners of a triangle to find a directed line segment that represent the crossing of the intensity value within the triangle, and an exit point of the directed line segment and a nearest triangle which contains the next directed line segment of the at least one iso-contour polygon are determined to create a first matrix of points on the at least one iso-contour polygon, until arriving at the original triangle.
