Class ThresholdBlockMean<T extends ImageGray<T>>

All Implemented Interfaces:
Direct Known Subclasses:
ThresholdBlockMean_F32, ThresholdBlockMean_U8

public abstract class ThresholdBlockMean<T extends ImageGray<T>> extends Object implements ThresholdBlock.BlockProcessor<T,T>

Applies a threshold to an image by computing the mean values in a regular grid across the image. When thresholding all the pixels inside a box (grid element) the mean values is found in the surrounding 3x3 grid region.\
