| cvCreateHist ( int dims, [ sizes, CvEnum type, [ ranges, bool uniform ) : IntPtr |
Creates a histogram of the specified size and returns the pointer to the created histogram. If the array ranges is 0, the histogram bin ranges must be specified later via The function cvSetHistBinRanges, though cvCalcHist and cvCalcBackProject may process 8-bit images without setting bin ranges, they assume equally spaced in 0..255 bins
|
|
| cvCreateSubdivDelaunay2D ( Rectangle rect, IntPtr storage ) : IntPtr |

|
|
| cvNamedWindow ( String name ) : int |
Creates a window which can be used as a placeholder for images and trackbars. Created windows are reffered by their names. If the window with such a name already exists, the function does nothing.
|
|
| cvPointPolygonTest ( IntPtr contour, PointF pt, bool measureDist ) : double |
Determines whether the point is inside contour, outside, or lies on an edge (or coinsides with a vertex). It returns positive, negative or zero value, correspondingly
|
|
| cvSnakeImage ( IntPtr image, IntPtr points, int length, float alpha, float beta, float gamma, int coeffUsage, Size win, MCvTermCriteria criteria, bool calcGradient ) : void |
Updates snake in order to minimize its total energy that is a sum of internal energy that depends on contour shape (the smoother contour is, the smaller internal energy is) and external energy that depends on the energy field and reaches minimum at the local energy extremums that correspond to the image edges in case of image gradient.
