Hough sum

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.
