Fig.6 Comparison of edge detection 5 结论 (1) 通过调整滤波参数可以改变各向异性扩散的滤波特性,即线性与非线性性,各向同性与各向异性. (2) 传统的各向异性扩散模型在一定条件下与Robust估计具有等价性,但对"飞点"噪声会引起扩散过程不稳定,发生反扩散.因此,随着扩散不断进行,可能会放大噪声干扰.中值滤波与线性滤波则会导致信... detection using anisotropic diffusion[J]. IEEE Trans PAMI, 1990, 12(7): 629-639.

of overlap coal particle in the image segmentation of coal piles, several image enhancement and edge detection methods were contrasted. An algorithm combined with contrast limited local histogram equalization (CLAHE) and SUSAN edge detection was used to detect the edges of coal particles. Mathematical morphology and filling algorithm were used to obtain the best seed regions, which was able......

normalisation, to avoid the introduction of the linear combination coefficient. 2) Corner detectors based on edge detection. KITCHEN and ROSENFELD [10] proposed a method on the gradient magnitude of the boundary...-time application. In Ref. [16], a three-layer neural network is trained to recognize corners, but it should be applied to image after edge detection and thinning. In the context of real-time detection......
