C++ (Cpp) CV_SUM_OFFSETS Examples

Example #1

File: lbpfeatures.cpp Project: 353/viewercv

CvLBPEvaluator::Feature::Feature(int offset, int x, int y, int _blockWidth, int _blockHeight) {
    Rect tr = rect = cvRect(x, y, _blockWidth, _blockHeight);
    CV_SUM_OFFSETS(p[0], p[1], p[4], p[5], tr, offset)
    tr.x += 2 * rect.width;
    CV_SUM_OFFSETS(p[2], p[3], p[6], p[7], tr, offset)
    tr.y += 2 * rect.height;
    CV_SUM_OFFSETS(p[10], p[11], p[14], p[15], tr, offset)
    tr.x -= 2 * rect.width;
    CV_SUM_OFFSETS(p[8], p[9], p[12], p[13], tr, offset)
}

Example #2

File: feature.cpp Project: 23pointsNorth/opencv_contrib

{
  rect[0] = Rect( x, y, cellW, cellH );  //cell0
  rect[1] = Rect( x + cellW, y, cellW, cellH );  //cell1
  rect[2] = Rect( x, y + cellH, cellW, cellH );  //cell2
  rect[3] = Rect( x + cellW, y + cellH, cellW, cellH );  //cell3

  for ( int i = 0; i < N_CELLS; i++ )
