In this paper we present an efficient method for aggregating binary feature\ndescriptors to allow compact representation of 3D scene model in incremental\nstructure-from-motion and SLAM applications. All feature descriptors linked\nwith one 3D scene point or landmark are represented by a single low-dimensional\nreal-valued vector called a \prototype. The method allows significant\nreduction of memory required to store and process feature descriptors in\nlarge-scale structure-from-motion applications. An efficient approximate\nnearest neighbours search methods suited for real-valued descriptors, such as\nFLANN, can be used on the resulting prototypes to speed up matching processed\nframes.\n
