<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<p>Performs Histogram Of Oriented Gradients operation on source image generating separate windows of Histogram Descriptors for each requested location. </p>
<p>This function implements the simplest form of functionality described by N. Dalal and B. Triggs. Histograms of Oriented Gradients for Human Detection. INRIA, 2005. It supports overlapped contrast normalized block histogram output with L2 normalization only, no threshold clipping, and no pre or post gaussian smoothing of input images or histogram output values. It supports both single channel grayscale source images and three channel color images. For color images, the color channel with the highest magnitude value is used as that pixel's magnitude. Output is row order only. Descriptors are output consecutively with no separation padding if multiple descriptor output is requested (one desriptor per source image location). For example, common HOG parameters are 9 histogram bins per 8 by 8 pixel cell, 2 by 2 cells per block, with a descriptor window size of 64 horizontal by 128 vertical pixels yielding 7 by 15 overlapping blocks (1 cell overlap in both horizontal and vertical directions). This results in 9 bins * 4 cells * 7 horizontal overlapping blocks * 15 vertical overlapping blocks or 3780 32-bit floating point output values (bins) per descriptor window.</p>
<p>The number of horizontal overlapping block histogram bins per descriptor window width is determined by (((oHOGConfig.detectionWindowSize.width / oHOGConfig.histogramBlockSize) * 2) - 1) * oHOGConfig.nHistogramBins. The number of vertical overlapping block histograms per descriptor window height is determined by (((oHOGConfig.detectionWindowSize.height / oHOGConfig.histogramBlockSize) * 2) - 1) The offset of each descriptor window in the descriptors output buffer is therefore horizontal histogram bins per descriptor window width * vertical histograms per descriptor window height 32-bit floating point values relative to the previous descriptor window output.</p>
<p>The algorithm uses a 1D centered derivative mask of [-1, 0, +1] when generating input magnitude and angle gradients. Magnitudes are added to the two nearest histogram bins of oriented gradients between 0 and 180 degrees using a weighted linear interpolation of each magnitude value across the 2 nearest angular bin orientations. 2D overlapping blocks of histogram bins consisting of the bins from 2D arrangements of cells are then contrast normalized using L2 normalization and output to the corresponding histogram descriptor window for that particular window location in the window locations list.</p>
