The 2-D wavelet transform in image processing: Two novel applications

Primary tabs

Antoine, Jean-Pierre [UCL] Jacques, Laurent [UCL]

In this paper, we describe two recent developments of the two-directional wavelet transform, namely, (i) the angular multiselectivity scheme and its application to image denoising, and (ii) a technique for measuring the curvature radius of a curve with application to astrophysical images. In both cases, the key is to use directional wavelets, with fixed or variable angular selectivity.
