Add a filter for noise variance estimation by pseudo residuals.
New macros provides a tic toc tool for time measurements of part of code.
Add tests for normal probability density.
Add source and tests for the von mises fisher distribution.
Enforces the positivity of the ODF model.
Add a diffusion signal class structure (signal is intensities divided by the baseline) and a diffusion sequence to diffusion signal filter.
Add copy constructor to gradient direction class.
Add a new constructor to vMF probability density class.
Changes to double precision for physical point coordinates.
Changes pseudo residuals variance calculator to use diffusion signal image.
Add new methods for diffusion models. The models can be computed with an arbitrary set of gradient directions.
Add method for normal density evaluation with a specified std deviation as function's parameter.
Clean source.
Changes the internal representation for mask image (uniformization with other stuffs).
Add a setter for pseudo residuals standard deviation in signal class.
Add initialize parent function for child filter initialization (called at the top of update member function).
Remove tensor particle filtering program (may be replaced by btkTractography unique executable).
Add the possibility to convert the gradient in world or image coordinates.
Fix bug (the gradient table was used before converting it into world/image coordinates.
Add floating equality macro functions.
