/* Program: cvlib_mex.c
* Purpose: matlab callable routine to interface with some OpenCV library functions
*
* Revision 1.0 31/08/2006 Joaquim Luis
* Revision 2.0 19/10/2006 JL Edge 'laplace' needed exlicit kernel input
* Revision 3.0 27/10/2006 JL Updated cvHoughCircles call to 1.0
* Revision 4.0 07/11/2006 JL Erode & Diltate in cvHoughCircles (almost the same shit)
* Revision 5.0 29/11/2006 JL Added half a dozen of functions more (line, rect, circ, poly, ellip, inpaint)
* Revision 6.0 02/12/2006 JL Added FillPoly and FillConvexPoly
