adaptiveThreshold
transforms a grayscale image to a
binary image using an adaptive threshold.
1 2 | adaptiveThreshold(image, max_value = 255, method = "mean",
threshold_type = "inverse", block_size = 31, C = 25)
|
image |
An an 8-bit (8U) single-channel |
max_value |
Non-zero numerical value assigned to the pixels above the adaptive threshold (default: 255). |
method |
The name of the adaptive thresholding algorithm to use. It can be either 'mean' - mean of the block_size * block_size neighborhood - or 'gaussian' - Gaussian weighted sum of the block_size * block_size neighborhood (default: 'mean'). |
threshold_type |
The name of the threshold type to use. It can be either 'binary' or 'inverse' (default: 'inverse'). |
block_size |
Size of a pixel neighborhood that is used to calculate a threshold value for the pixel (default: 31). |
C |
Constant subtracted from the mean or weighted mean. Normally, it is positive but may be zero or negative as well (default: 25). |
An Image
object.
