Patent Images

1. A method of determining alignment of decorelating images in high dimensional feature space, said method comprising:

  • simultaneously registering a source image of a reference modality to a plurality of target images of a second modality with an algorithm based upon a measure of information affinity present in both of the source and target images to create a registered image;

    extracting a plurality of feature vectors from the registered image for each of the source and target images;

    plotting a distribution of the feature vectors on an entropic graph;

    determining edge lengths between the feature vectors from the entropic graph; and

    determining a similarity measure of one of an α

    -divergence estimate or an α

    -affinity estimate based upon these edge lengths to indicate whether the source and target images are sufficiently registered.
