  • To solve the problem of capturing only limited directional information in image edge detection method based on space domain or wavelet transform domain, the Contourlet transform with parabolic scaling and sufficient directional vanishing moments is used to represent discontinuous curves in nature images more efficiently. The algorithm detecting modulus maxima in Contourlet subbands has lower computation complexity, because Contourlet subbands obtain much more directions than wavelet subbands. Experimental results demonstrate that the proposed scheme is superior to the scheme based on wavelet modulus maxima by approximating better the edges of images.
