Abstract

A method which can detect multi-pixels edge of image is put forward. The method is based on difference of gray-level between the border upon pixels. To a 256 by 256 image, it needs 0.22 second to detect edge which is 26% and 34% faster respectively than that of Prewitt and Robert arithmetic. After ameliorating arithmetic, horizontal and vertical edge of image is detected integrality. The image edge doesn't exit in the edge detecting result of Prewitt and Robert arithmetic. Through thinning arithmetic, clear and precision location single pixel edge is achieved. The result show that, the multi-pixels edge detecting, improved and thinning method is of simple model and perfect real-time quality. The whole system can be realized easily.
