AdaptiveThreshold(InputArray, OutputArray, double, AdaptiveThresholdTypes, ThresholdTypes, int, double)

Applies an adaptive threshold to an array.

public static void AdaptiveThreshold(InputArray src, OutputArray dst, double maxValue, AdaptiveThresholdTypes adaptiveMethod, ThresholdTypes thresholdType, int blockSize, double c)

Parameters

src InputArray

Source 8-bit single-channel image.

dst OutputArray

Destination image of the same size and the same type as src .

maxValue double

Non-zero value assigned to the pixels for which the condition is satisfied. See the details below.

adaptiveMethod AdaptiveThresholdTypes

Adaptive thresholding algorithm to use, ADAPTIVE_THRESH_MEAN_C or ADAPTIVE_THRESH_GAUSSIAN_C .

thresholdType ThresholdTypes

Thresholding type that must be either THRESH_BINARY or THRESH_BINARY_INV .

blockSize int

Size of a pixel neighborhood that is used to calculate a threshold value for the pixel: 3, 5, 7, and so on.

c double

Constant subtracted from the mean or weighted mean (see the details below). Normally, it is positive but may be zero or negative as well.
