Parameters

request: A System.Runtime.Serialization.DataContractAttribute containing the data that will be used in this AutoBinary operation.

Return Value

A System.Runtime.Serialization.DataContractAttribute containing the modified image resulting from the HistogramEqualize operation.

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 operation 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 operation does not support signed data images.
This operation does not support 32-bit grayscale images.

Use the AutoBinary when you simply want to apply binary segmentation to the bitmap using an automatically calculated threshold based on a two-peak method of statistical analysis on its histogram. Use the DynamicBinary to convert an image into a black and white image without changing its bits per pixel.
