We propose a considerably faster approximation of the well known SIFT method. The main idea is to use efficient data structures for both, the detector and the descriptor. The detec...
This paper explores the use of camera phones with pen input as a platform for generating digital annotations to realworld objects. We analyze the client-side requirements for a ge...
Abstract. Motion estimation is essential in a variety of image processing and computer vision tasks, like video coding, tracking, directional filtering and denoising, scene analys...
This paper presents the cache configuration exploration of a programmable system, in order to find the best matching between the architecture and a given application. Here, prog...
