LocalThreshold Method
Syntax
CWIMAQVision.LocalThreshold SourceImage, DestImage, Options
Return Type
On success, this method returns 0. On failure, this method returns a negative number.
Purpose
Automatically thresholds an image into a binary image based on the requested local adaptive thresholding method.
Remarks
Use this method with U8 and I16 images. All of the images you pass to this method must be of the same type.
The window size you specify in Options should be sized as large as possible but small enough that each window contains pixels under similar lighting conditions. This method will produce inconsistent results for windows that contain uniform pixel values.
Parameters
SourceImage As CWIMAQImage
The image to threshold.
DestImage As CWIMAQImage
The resulting image.
Options As CWIMAQLocalThresholdOptions
Specifies the options to use to perform the local threshold.
