Operation: auto threshold

auto threshold operation

Author:

The operation uses the methods threshold and getAutoThreshold from the imageJ class ImageProcessor.

Example

test sourcetest dest

Description

The threshold operation sets all intensities above the threshold value to the maximum (255) and all below to the minimum (0). The threshold value is computed iteratively. The iteration stops when the threshold is above the composite average of the two classes. See imageJ documentation for details.

Options

none

Parameter

The input image must be a 8bit greyscale image.

Results

The result is a 8bit greyscale image that contains only the intensities 0 and 255.
