LTI-Lib (C++ Computer Vision Library) Code

@ADD: Vlad Popovici's lti::rotation functor has been added to the library. It uses the "Rotation by Shear" algorithm which is some times slightly faster than the lti::geometricTransform. In general, the current algorithm is slower in the debug version, and in the release is always faster rotating angles around 45, 135, -135 and -45 degrees, and much much faster for rotations of exactly k*90 degrees. For the angles around k*90, the lti::geometricTransform using bilinear interpolation is still faster, and using the kNearestNeighbor interpolation even faster than the new one. The algorithm may change in the future to increase efficiency.

alvarado: Undefine the "None" macro, to allow its use as constant in an enum. Oh, those awful C things...

doerfler: forgot to comment out _LTI_DEBUG

alvarado: stdio.h replace by cstdio

alvarado: Doxygen warnings fixed.

alvarado: Allow to set the data of a known element.

Now check for --disable-debug or --enable-debug with the AC_LIB_VERSIONS macro in acinclude.m4

Adapted to use as default target only those libraries specified by the user with the configure script.

@ADD: In Linux, the configure script now accepts the options --disable-debug or --disable-release to suppress the automatic compilation of the debug or release libraries respectively. Without them, both libraries will be compile when only "make" is given. Of course, you still can combile the debug or release libraries with the corresponding targets.
