Summary

Detect Glyphs marks in an image. Returns the geometry of the mark and a score of confidence level. Speed is more important than accuracy.

Parameters

context		Specify context.
image		Sepecify which image to analyze.
rect		Specify a region of the image, or NULL for the entire image
angle		Specifify maximum angle to search through (radians)

Output Parameters

angle		Returns the angle of the cell size (radians).
cellWidth		Returns the width of the cell.
cellHeight		Returns the height of the cell.
score		Returns a score of the confidence level of the detection. Scores can range from 0 to some decently high number, and should be considered relative to each other rather than by their absolute value.
