CudaInvokeThreshold Method |
http://www.emgu.com
Applies fixed-level thresholding to single-channel array. The function is typically used to get bi-level (binary) image out of grayscale image or for removing a noise, i.e. filtering out pixels with too small or too large values. There are several types of thresholding the function supports that are determined by thresholdType

Parameters
- src
- Type: Emgu.CVIInputArray
Source array (single-channel, 8-bit of 32-bit floating point). - dst
- Type: Emgu.CVIOutputArray
Destination array; must be either the same type as src or 8-bit. - threshold
- Type: SystemDouble
Threshold value - maxValue
- Type: SystemDouble
Maximum value to use with CV_THRESH_BINARY and CV_THRESH_BINARY_INV thresholding types - thresholdType
- Type: Emgu.CV.CvEnumThresholdType
Thresholding type - stream (Optional)
- Type: Emgu.CV.CudaStream
Use a Stream to call the function asynchronously (non-blocking) or null to call the function synchronously (blocking).
Return Value
