detectEdges method

Mat detectEdges(
  1. InputArray src
)

The function detects edges in src and draw them to dst.

The algorithm underlies this function is much more robust to texture presence, than common approaches, e.g. Sobel

Implementation

Mat detectEdges(InputArray src) {
  cvAssert(src.type.depth == MatType.CV_32F);
  final p = calloc<cvg.Mat>();
  cvRun(() => cffi.ximgproc_StructuredEdgeDetection_detectEdges(ref, src.ref, p));
  return Mat.fromPointer(p);
}
