IBitmapImageBuildNormalizedHog Method

Builds normalized Histograms of oriented gradients for a given image using block size of 8x8 pixels. Normalizes the Hog in to a single array of gradients. Each successive group of 36 elements ((2 x 2) x (9 x 1) histogram) represents gradients (at angles 0, 20, 40, 60, 80, 100, 120, 140, and 160 degrees) in a 16x16 pixel window. This window slides over 8-pixel intervals, starting at top left of image.
