A Matlab toolbox for visualization of image manifolds
Kevin Eykholt, Marco F. Duarte · 2013
While manifolds have attracted significant attention from the image processing and computer vision communities, we are not aware of openly available tools for visualization of manifold-modeled data that allows for interactive navigation over the embedded dataset. We introduce the Manifold Analysis GUI (MAGI), a freely available toolbox for Matlab that provides a navigation interface for manifold-modeled image datasets. The inputs to MAGI are a matrix of image data and a corresponding matrix of their embedding coordinates; the toolbox also includes an implementation of Isomap to provide a default nonlinear embedding. MAGI displays a 2-D projection of the embedding that can be navigated interactively, showing the image corresponding to the embedding point closest to the mouse cursor.
