Edge detection using joint transform correlation
Mohammad S. Alam, Boon Yi Soon · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1997
A new joint wavelet transform correlation based technique is proposed for feature extraction such as detection of edges in an unknown input scene. We exploited a modified version of the Roberts and Sobel wavelet filters as the reference images for extracting the edges of an unknown input scene. The performance of the proposed technique using the aforementioned wavelet filters are evaluated and compared using numerical simulations.
