Constructor Detail

AdaptiveLocalThresholdGaussian

public AdaptiveLocalThresholdGaussian(float sigma,
                                      float offset)

Construct the thresholding operator with the given Gaussian standard deviation, sigma, and offset

Parameters:

sigma - Gaussian kernel standard deviation

offset - offset from the patch mean at which the threshold occurs

Method Detail

processImage

public void processImage(FImage image)

Description copied from interface: ImageProcessor

Process an image. Implementing classes must alter the image passed in-place or assign the output to the input using Image.internalAssign(Image).

Specified by:

processImage in interface ImageProcessor<FImage>

Parameters:

image - The image to process in place.
