std::vector< HomgPoint2D > &  points2d,
std::vector< Vector3< StorageType > > &  colors,
bool  useMedian = false 
) [virtual]

Detects constant regions in image src.

Constant regions around pixels in images are detected by a histogram-based method, that is applied to windows around the pixel in question. The differences in color are compared. threshold is the allowed average deviation from the color of the middle pixel. halfWinSize the size of the window used for detection. if useMedian is set to true, the input image will be filtered by a median filter first. The result is written into a vector with homogenuous 2D points and a segmentation image.
