发明名称 Contour extraction method and apparatus
摘要 In a contour extraction apparatus and method, states of target pixels and pixels adjacent to the respective target pixels in image data are held, the target pixel is taken out in the sequence of raster scanning, and a pixel arranging vector in the horizontal direction and in the vertical direction is detected according to the state of the target pixel and pixels adjacent to the target pixel. A state of connection between the pixel arranging vectors is determined, and a contour of the image data is extracted according to the determined state of connection between the pixel arranging vectors. <IMAGE>
