Hough sumΒΆ

This result calculates the total intensity of the pixels in the HoughMap. In other words, it sums the intensity of every pixels.

Q = \sum\limits_{i=0}^{W}{\sum\limits_{j=0}^{H}{I_{ij}}}

where W is the width, H is the height of the HoughMap and I_{ij} the pixel value at position (i, j).

Results from this quality metric are similar to the pattern-sum operation.
