found a bug in Qtpftsgui, thought you may be interested.
If you use the Durand transform, and set the Range Kernel Sigma parameter to value = 0, then the Apply will cause Qtpftsgui to fall over.
The problem may arise in the following line of module /trunk/qtpfsgui/src/TM_operators/durand02/fastbilateral.cpp:
(jG)(i) = exp( -(dIdI) / (sigma_r*sigma_r) );
To prevent the problem from happening, one possible solution is to limit the lower value for the Range Kernel Sigma parameter in the GUI so that it can not be set to 0.
