This ImageJ plugin demonstrates the use of the SIFT detection and matching framework. See Sec. 25.5 of [1] for details.

The plugin takes a single image, which is assumed to be composed of a left and right frame. The input image is split horizontally, then SIFT detection and matching is applied to the two sub-images. The input image is always converted to grayscale (and normalized to [0,1]) before SIFT feature detection is performed. The result is displayed as a graphic overlay by connecting and annotating the best-matching features. When saved as a TIFF image the overlay is preserved.
