cvCvtColor metodu - C İçi şöyledir.

CV_IMPL void cvCvtColor( const CvArr* srcarr, CvArr* dstarr, int code )
{
  cv::Mat src = cv::cvarrToMat(srcarr), dst0 = cv::cvarrToMat(dstarr), dst = dst0;
  CV_Assert( src.depth() == dst.depth() );

  cv::cvtColor(src, dst, code, dst.channels());
  CV_Assert( dst.data == dst0.data );
}

floodFill metodu
Açıklaması şöyle

Flood fill, also called seed fill, is an algorithm that determines the area connected to a given node in a multi-dimensional array. It is used in the "bucket" fill tool of paint programs to fill connected, similarly-colored areas with a different color, and in games such as Go and Minesweeper for determining which pieces are cleared. When applied on an image to fill a particular bounded area with color, it is also known as boundary fill.

Algoritma şöyle

1. Mark all empty cells as unknown (all full cells are unreachable)
2. Add the source cell to a set of routable cells
3. While the set is not empty:
  - pop an element from the set;
  - mark all adjacent unknown cells as "reachable" and add them to the set
4. All remaining unknown cells are unreachable.

threshold metoduŞöyle yaparız.

laplacian_img_RGB = cv2.cvtColor(laplacian_img, cv2.COLOR_GRAY2BGR)

ret, thresh = cv2.threshold(laplacian_img, 140, 255, cv2.THRESH_BINARY)
