LEADTOOLS WCF Image Processing (Leadtools.Services.ImageProcessing.ServiceContracts assembly)
LEAD Technologies, Inc

DynamicBinary Method

Example 





A System.Runtime.Serialization.DataContractAttribute containing the data that will be used in this DynamicBinary operation.
Converts an image into a black and white image without changing its bits per pixel by using a local threshold value for each pixel of the image. This operation is useful for pre-processing images for the purpose of improving barcode recognition results.

Parameters

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

Return Value

A System.Runtime.Serialization.DataContractAttribute containing the modified image resulting from the HistogramEqualize operation.
Remarks
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 AutoBinary to convert an image into a black and white image without changing its bits per pixel.
