public class ColourASIFT extends ASIFT<MBFImage,Float>
DoGColourSIFTEngineis used internally to find the features. Specifically, the
DoGColourSIFTEnginecreates a luminance image from which to apply the difference-of-Gaussian interest point detection algorithm, but extracts the actual SIFT features from the bands of the input image directly. This means that the type of Colour-SIFT feature is controlled directly by the colour-space of the input image; for example if an RGB image is given as input, then the feature will be standard RGB-SIFT.
