Method and apparatus for locating the boundary of an object |
摘要 |
An apparatus and method for automatically locating the boundary of an object in a field of view has a raster scan device to generate an electrical image of the field of view. The electrical image is segmented and digitized to form a first representation. The image is then processed by comparing the digitized signal to a pre-set threshold to form a second representation. A converter combines each value of the pixel of the second representation with the values of the adjacent pixels into a single value and stores it in a corresponding location in a third representation. The values of the pixels in the third representation are read out and compared to a look-up table. A chain code of the boundary of the particle is formed from the look-up table.
