VOW: Variance-Optimal Wavelets for the Steerable Pyramid
2014
Proceedings of the 2014 IEEE International Conference on Image Processing (ICIP'14)
We study the issue of localization in the context of isotropic wavelet frames. We define a variance-type measure of localization and propose an algorithm based on calculus of variations to minimize this criterion under the constraint of a tight wavelet frame. Based on these calculations, we design the variance-optimal wavelet (VOW). Finally, we demonstrate the advantage of better localization in a practical image-processing task.
