| Abstract: | The reason for the low speed of SUSAN algorithm in comer detection is analyzed, and a hierarchical fast comer detection algorithm based on SUSAN algorithm is proposed. According to the gray similarity around pixels and the comer properties in an image, the theory of lifting wavelet transform and the coarse-to-fine hierarchical strategy are adopted to process the image, with the aim of finding the coarse positions of comers. Then, the comers are finely searched and precisely located by using SUSAN algorithm. Experimental results show that the proposed algorithm runs fast and saves much runtime. |
