Method and apparatus for automatic shape recognition

摘要: A method and apparatus are disclosed for determining whether a shape or pattern exists anywhere in particular image represented by matrix of digital data signals. In the preferred embodiment, suitably programmed general purpose computer provides means storing signals representing first image, computing complement matrix, creating structuring element representative target to be recognized that element, second equal window element. One more substantially identical neighborhood transformation stages then employed electronically eroding with form matrix. The corresponding points matrices combined result wherein each non-zero point represents location desired image.
