AutoBinaryCommand Class
See Also  Members   Example 




Applies binary segmentation to the image using an automatically calculated threshold based on a two-peak method of statistical analysis of the histogram. This command is available in the Document/Medical Toolkits.

Remarks

  • The image is transformed into a binary image using a threshold calculated automatically based on statistical features of the image. Best results are obtained with grayscale images.
  • This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • If the image has a region, the effect will be applied on the region only.
  • This command does not support signed data images.
  • This command does not support 32-bit grayscale images.
