Detailed Description

Segments an image using a double threshold on a grayscale image.

Remarks:

This segmenter is applicable to eVision.EROIBW8 and eVision.EROIBW16 grayscale images. It produces coded images with three layers: The Black layer (usually, with index 0) contains the unmasked pixels having a gray value strictly below the low threshold value; the White layer (usually, with index 2) contains the unmasked pixels having a gray value above or equal to the high threshold value; and the Neutral layer (usually, with index 1) contains the remaining unmasked pixels.
