摘要：Most of the sub-pixel edge detection methods proposed in literature are based on Ghosal and Mehrotra’s method which uses Zernike moments. Some research has been reported using Fourier-Mellin moments for sub-pixel edge detection. Pseudo Zernike moments have been proved to be superior to Zernike moments in terms of their feature representation capabilities and sensitivity to image noise. This paper proposes the use of Pseudo Zernike moments for sub-pixel edge detection. Testing of the proposed algorithm shows significantly better results than Zernike and Fourier-Mellin moment based methods in case of images corrupted with additative or multiplicative noise .
