Fixed bug #832 1. Changed line 484 to use 'normalize' function instead of performing operation inline. This format follows the convention elsewhere in code 2. Changed all lines comparing normalize(d) to grayThreshold to round the result of normalize. 	Normalize was returning a value of greater precision that grayThreshold, which would make it 'larger than' simply from the extra precision.
