Description: The inflection point in the digital image are important information carriers, so accurate, stable and real-time detection of the inflection point will become the main problem of inflection point detection algorithm face L, to solve this problem, we propose a new two value image in the inflection point of the real-time detection algorithm. The algorithm with the traditional inflection point algorithm of edge detection based on chain code, which is firstly constructed pixel K (k>8) neighborhood, and the image object boundary representation for K neighborhood chain code; then according to the definition of curvature curvature difference form to calculate the boundary point; precise local peak location finally tested by the curvature histogram of a turning point, and the use of internal corner pixel color statistical information to quickly determine the convexity of the inflection point.
