Edge detection method and apparatus for an image processing system |
摘要 |
An edge detection apparatus and method for an image processing system are disclosed. The apparatus comprises a conversion means for converting input pixel data into tri-state valves, a matching means for obtaining inner products of tri-state valves and prespecified edge patterns and a decision means for determining the pixel data to be an edge when the pixel data is equal to the tri-state values. The edge detection apparatus can remove noise without an additional low pass filters, simplify the hardware and do real time process. |
