% toufig15 -- Tour Figure 15: Display Vaguelette Kernels
%
% (Panels a-c) display three mother vaguelettes used in inversion
% of the Radon transform. The integral of sine-o-gram data
% against these vaguelettes will result in estimates
% of wavelet coefficients at scale-location (0,0) and orientation
% {Horizontal, Vertical, Diagonal}. (Panel d) shows one vaguelette 
% having undergone twisted dilation, so that it measures the wavelet 
% coefficient at scale 2^{-3} and location (kx=4,ky=2)
