optimize

public RotationOffset optimize(ImageWrapper<org.opencv.core.Mat> ref,
                               ImageWrapper<org.opencv.core.Mat> current,
                               int numberOfIterations,
                               int positionalRadius,
                               int rotationalRadius,
                               int stepsOfInterestingPoints,
                               double degressionRate,
                               RGBColor paddingFillColor)

Method for calculating the offset of two images in an optimized way.

Specified by:

optimize in interface Optimizer<org.opencv.core.Mat>

Parameters:

ref - The image which is used for comparison.

current - The image which should be compared with ref

numberOfIterations - Max. number of iterations which should be done.

positionalRadius - The search window for positional offset (look between -positionalRadius to +positionRadius. e.g. if image is translated max +/- 10 pixels on x-axis and y-axis)

rotationalRadius - The search window for rotational offset (look between -rotationalRadius to +rotationalRadius. e.g. if image is translated max +/- 2 degrees)

stepsOfInterestingPoints - Defines each x points which are interesting for feature detection. E.q. with = 3 just every third point will be used as feature.

degressionRate - degression of positionalRadius and rotationalRadius per iteration

paddingFillColor - Color which is used for filling new pixels after padding.

Returns:

Rotational and Translational offset between ref and current

optimize

public RotationOffset optimize(ImageWrapper<org.opencv.core.Mat> ref,
                               ImageWrapper<org.opencv.core.Mat> current)

This method optimizes the quality and/or the speed of image processing algorithms.

Specified by:

optimize in interface Optimizer<org.opencv.core.Mat>
