Detailed Description

Segments an image using a pixel-by-pixel single threshold given as an image.

Remarks:

This segmenter is applicable to eVision.EROIBW8, eVision.EROIBW16 and eVision.EROIC24 images. It produces coded images with two layers. The threshold is defined for each pixel individually by means of a reference image of the same type as the source image.

For grayscale images, the White layer (usually, with index 1) contains unmasked pixels having a gray value in a range defined by the gray value of the respective pixel in the reference image and the white color.

For RGB color images, the White layer (usually, with index 1) contains unmasked pixels having a color inside the cube of the RGB color space defined by the color of the respective pixel in the reference image and the white color (255,255,255).

The Black layer (usually, with index 0) contains the remaining unmasked pixels.
