摘要：
Classical edge extraction is difficult for these images with the interference of non-distribute objects and uneven lighting. A new edge extraction approach combining Canny algorithm and Butterworth high-pass filter is proposed. Butterworth high-pass filter highlights objects and removes the background and some interference information in ore image. After histogram specification enhancing the contrast, Canny algorithm extracts accurate edges in these processed images. The experiments show that the result of new edge extraction method for complex ore images is more excellent than that of single Canny algorithm, it not only retains more closed edge, but also remove the noise and false edge.
