LocalThresholdMethod
The method the function uses to perform the local threshold.
Elements
| Name | Value | Description |
|---|---|---|
| IMAQ_NIBLACK | 0 | The function computes thresholds for each pixel based on its local statistics using the Niblack local thresholding algorithm. |
| IMAQ_BACKGROUND_CORRECTION | 1 | The function performs background correction first to eliminate non-uniform lighting effects, then performs thresholding using the Otsu thresholding algorithm. |
| IMAQ_LOCAL_THRESHOLD_METHOD_SIZE_GUARD | 0xFFFFFFFF | Reserved |
