Class DescribePointPixelRegionNCC<T extends ImageGray>

java.lang.Object

boofcv.alg.feature.describe.DescribePointRectangleRegion<T>

boofcv.alg.feature.describe.DescribePointPixelRegionNCC<T>

Direct Known Subclasses:

ImplDescribePointPixelRegionNCC_F32, ImplDescribePointPixelRegionNCC_U8

public abstract class DescribePointPixelRegionNCC<T extends ImageGray>
extends DescribePointRectangleRegion<T>

Describes a rectangular region using its raw pixel intensities which have been normalized for intensity. This allows the descriptor to be light invariant. The entire region must be inside the image for a descriptor to be computed because any outside values will change its intensity normalization.

Method Summary

Modifier and Type	Method and Description
boolean	isInBounds(int c_x, int c_y) The entire region must be inside the image because any outside pixels will change the statistics
abstract void	process(int c_x, int c_y, NccFeature desc) Extracts the descriptor at the specified location.

Method Detail

isInBounds

public boolean isInBounds(int c_x,
                          int c_y)

The entire region must be inside the image because any outside pixels will change the statistics

process

public abstract void process(int c_x,
                             int c_y,
                             NccFeature desc)

Extracts the descriptor at the specified location.

Parameters:

c_x - Center of the descriptor region.

c_y - Center of the descriptor region.

desc - Where the description is written to.
