Efficient matchings and mobile augmented reality

Efficient matchings and mobile augmented reality Efficient Matchings and Mobile Augmented Reality WEI GUAN, SUYA YOU and ULRICH NEWMANN, University of Southern California, Los Angeles With the fast-growing popularity of smart phones in recent years, augmented reality (AR) on mobile devices is gaining more attention and becomes more demanding than ever before. However, the limited processors in mobile devices are not quite promising for AR applications that require real-time processing speed. The challenge exists due to the fact that, while fast features are usually not robust enough in matchings, robust features like SIFT or SURF are not computationally efficient. There is always a tradeoff between robustness and efficiency and it seems that we have to sacrifice one for the other.

Abstract

Efficient Matchings and Mobile Augmented Reality WEI GUAN, SUYA YOU and ULRICH NEWMANN, University of Southern California, Los Angeles With the fast-growing popularity of smart phones in recent years, augmented reality (AR) on mobile devices is gaining more attention and becomes more demanding than ever before. However, the limited processors in mobile devices are not quite promising for AR applications that require real-time processing speed. The challenge exists due to the fact that, while fast features are usually not robust enough in matchings, robust features like SIFT or SURF are not computationally efficient. There is always a tradeoff between robustness and efficiency and it seems that we have to sacrifice one for the other. While this is true for most existing features, researchers have been working on designing new features with both robustness and efficiency. In this article, we are not trying to present a completely new feature. Instead, we propose an efficient matching method for robust features. An adaptive scoring scheme and a more distinctive descriptor are also proposed for performance improvements.
