Method Detail

getFitness

public double getFitness(ImageWrapper<org.opencv.core.Mat> a,
                         ImageWrapper<org.opencv.core.Mat> b,
                         RGBColor dataToIgnore)

This function is used to calculate similarity of two images.

Specified by:

getFitness in interface FitnessFunction<org.opencv.core.KeyPoint,org.opencv.core.Mat>

Parameters:

a - The feature which should be compared with b.

b - The feature which is used for comparison.

dataToIgnore - Data which should be ignored fo fitness calculation (e.g. Background color of an image). Can be null. Then no data will be ignored.

Returns:

Returns a metrics representing the difference of a and b. (0 = no differences)

getFitness

public double getFitness(ImageWrapper<org.opencv.core.Mat> a,
                         ImageWrapper<org.opencv.core.Mat> b)

This function is used to calculate similarity of two images

Specified by:

getFitness in interface FitnessFunction<org.opencv.core.KeyPoint,org.opencv.core.Mat>

Parameters:

a - The image which should be compared with b.

b - The image which is used for comparison.

Returns:

Returns a metrics representing the difference of a and b. (0 = no differences)

getFitness

public double getFitness(FeatureWrapper<org.opencv.core.KeyPoint> a,
                         FeatureWrapper<org.opencv.core.KeyPoint> b)

This function is used to calculate similarity of two features.

Specified by:

getFitness in interface FitnessFunction<org.opencv.core.KeyPoint,org.opencv.core.Mat>

Parameters:

a - The feature which should be compared with b.

b - The feature which is used for comparison.

Returns:

Returns a metrics representing the difference of a and b. (0 = no differences)
