A filter that returns a specified value for each pixel with a value greater than a specified threshold or 0 otherwise.

Declaration

class MPSImageThresholdBinary

Overview

An MPSImageThresholdBinary filter converts a single channel image to a binary image. If the input image is not a single channel image, the function first converts the input image into a single channel luminance image using the linear gray color transform, and then it applies the threshold.

The following listing shows the threshold binary function.
