Description

This X-Function converts the input image into a binary image automatically. The threshold used to perform the conversion is calculated based on statistical features of the input image.

This X-Function works best with gray images. If the input image is a color image, each channel of it will be separately binarized.

Note that this X-Function does not have a dialog.

Examples

In this example, we use the imgAutoBinary function to convert the input image to a binary image:

  1. When the input image is active, select Image: Conversion: Auto Binary. This performs the conversion and the input image is modified.
