| Abstract: | Based on the demand for image enhancement in corner extraction of image segmentation, this paper researches homomorphic filtering technique. It introduces homomorphic filtering in both frequency domain and spatial domain. Further, it proposes to use wavelet transform in homomorphic filtering. Experimental results are presented to illustrate the performance of this algorithm. Through comparison, the algorithm that can improve the correctness of corner extraction is proved. |
