Parameters

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

Return Value

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

This operation removes 1-pixel speckles, and shrinks some larger speckles. Therefore, in some cases, larger speckles can be completely removed by running it more than once.
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.
This operation does not support 32-bit grayscale images.
