专利汇可以提供Method and device for detecting elliptic shape专利检索,专利查询,专利分析的服务。并且PURPOSE: To detect plural ellipses reliably by regarding an edge picture of a picture as a two-dimensional spectral field and applying half conversion to it.
CONSTITUTION: An edge picture generator 1 calculates an edge spectrum by the primary differentiation of an input picture. The maximum values x
0 and y
0 of the mid-point histogram of a mid-point histogram generator 2 are detected by a two-dimensional maximum value detector 3 from positions (x) and (y) and directions dx and dy of the edge which are outputted by the generator 1. A (H, B) histogram generator 4 generates a histogram in space by using those (x), (y), dx, dy, x
0 , and y
0 , and a two-dimensional maximum value detector 5 detect maximum values H and B. The (x), (y), dx, dy, x
0 , and y
0 , and the outputs H and B of the detector 5 are used by a C histogram generator 6 to generate a histogram relating to a coefficient C, and a linear maximum value detector 7 detects its maximum value C.
