This function does exactly that. IJT and descJT are the images/cuboids jittered and their associated descriptors jittered, where IDXr was returned by jitter_kmeans. INPUTS IDXr - see jitter_kmeans IJT - ... xNxR array descJT - [optional] NxPxR array OUTPUTS I - ...xN array desc - NxP array See also JITTER_KMEANS
