Package boofcv.alg.filter.binary

Class ThresholdBlockMean<T extends ImageGray<T>>

java.lang.Object

boofcv.alg.filter.binary.ThresholdBlockMean<T>

All Implemented Interfaces:

ThresholdBlock.BlockProcessor<T,T>

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.\

See ThresholdBlockMinMax for a more detailed discussion of elements of this strategy
