MatAdaptiveThreshold Method

Applies an adaptive threshold to an array. Source matrix must be 8-bit single-channel image.

Namespace:  OpenCvSharp
Assembly:  OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0
Syntax
public Mat AdaptiveThreshold(
	double maxValue,
	AdaptiveThresholdTypes adaptiveMethod,
	ThresholdTypes thresholdType,
	int blockSize,
	double c
)

Parameters

maxValue
Type: SystemDouble
Non-zero value assigned to the pixels for which the condition is satisfied. See the details below.
adaptiveMethod
Type: OpenCvSharpAdaptiveThresholdTypes
Adaptive thresholding algorithm to use, ADAPTIVE_THRESH_MEAN_C or ADAPTIVE_THRESH_GAUSSIAN_C .
thresholdType
Type: OpenCvSharpThresholdTypes
Thresholding type that must be either THRESH_BINARY or THRESH_BINARY_INV .
blockSize
Type: SystemInt32
Size of a pixel neighborhood that is used to calculate a threshold value for the pixel: 3, 5, 7, and so on.
c
Type: SystemDouble
Constant subtracted from the mean or weighted mean (see the details below). Normally, it is positive but may be zero or negative as well.

Return Value

Type: Mat
Destination image of the same size and the same type as src.
