Field Detail

VOIs

private VOIVector VOIs

Non-maximal suppression for features/corners Non maxima suppression and thresholding for points generated by a feature or corner detector. Note: An issue with integer valued images is that if there are multiple pixels all with the same value within distance 2*radius of each other then they will all be marked as local maxima.

Constructor Detail

AlgorithmNonMaxSuppts

public AlgorithmNonMaxSuppts(ModelImage destImg,
                             ModelImage srcImg,
                             VOIVector VOIs,
                             int radius,
                             double threshold)

Parameters:

destImg - Optional image. If this is supplied, the thresholded corners are overlayed on this image. This can be useful for parameter tuning

srcImg - Corner strength image

VOIs -

radius - Radius of the region considered in non-maximal suppression. Typical values to use might be 1-3 pixels.

threshold -

hcd - byte buffer containing corner points

AlgorithmNonMaxSuppts

public AlgorithmNonMaxSuppts(ModelImage destImg,
                             ModelImage srcImg,
                             VOIVector VOIs,
                             int radius,
                             double threshold,
                             double[] xsubp,
                             double[] ysubp)

Parameters:

destImg - Optional image. If this is supplied, the thresholded corners are overlayed on this image. This can be useful for parameter tuning

srcImg - Corner strength image

VOIs -

radius - Radius of the region considered in non-maximal suppression. Typical values to use might be 1-3 pixels.

threshold -

xsubp - Sub-pixel localization of feature points is attempted and returned as as additional set of floating point coordinates. Note that you may still want to use the integer valued coordinates to specify centers of correlation windows for feature matching.
