Method Detail

calculateDeltaE

public static double calculateDeltaE(double[] lab1,
                     double[] lab2)

Calculate the colour difference value between two colours in lab space.

Parameters:

lab1 - first colour

lab2 - second colour

Returns:

the CIE 2000 colour difference

calculateDeltaE

public static float calculateDeltaE(float[] lab1,
                    float[] lab2)

Calculate the colour difference value between two colours in lab space.

Parameters:

lab1 - first colour

lab2 - second colour

Returns:

the CIE 2000 colour difference

calculateDeltaE

public static float calculateDeltaE(Float[] lab1,
                    Float[] lab2)

Calculate the colour difference value between two colours in lab space.

Parameters:

lab1 - first colour

lab2 - second colour

Returns:

the CIE 2000 colour difference

calculateDeltaE

public static double calculateDeltaE(double L1,
                     double a1,
                     double b1,
                     double L2,
                     double a2,
                     double b2)

Calculate the colour difference value between two colours in lab space.

Parameters:

L1 - first colour's L component

a1 - first colour's a component

b1 - first colour's b component

L2 - second colour's L component

a2 - second colour's a component

b2 - second colour's b component

Returns:

the CIE 2000 colour difference

makeDisparityMap

public static FImage makeDisparityMap(MBFImage im1,
                      MBFImage im2)

Compute the disparity map between two images. If the images are not in Lab colour space, then copies in lab space will be created.

Parameters:

im1 - The first image.

im2 - The second image.

Returns:

the disparity map between the colours in the two images.

combine

public FImage combine(MBFImage image1,
             MBFImage image2)

Description copied from interface: ImageCombiner

Perform processing that combines the two images into a single image.

Specified by:

combine in interface ImageCombiner<MBFImage,MBFImage,FImage>

Parameters:

image1 - the first image

image2 - the second image

Returns:

the output image
