Abstract
In this work, we implement three visual tracking techniques on mobile devices, i.e., a face tracking method using Haar-like features, a motion estimation method using 2D logarithmic search, and a circle tracking method by detecting a red circle attached on the user’s forehead. We use these three methods for mobile display stabilization alternatively and compare their performances. As visual tracking is a time consuming process and difficult running smoothly on mobile devices, the circle tracking method outperforms the other two by its simple computing process. We then validate the circle tracking based stabilization mechanism using the tumbling E eye examination and subjective 10-point scale questionnaire. Experimental results revealed that the proposed mechanism successfully reduced sight discomfort during motion, such as walking, taking a bus, and taking the Taipei MRT.
Highlights
Visual tracking [1,2,3] has been an important research topic and gains increasing attention due to popular distribution of camera systems, visual tracking techniques are still time consuming and take a lot of computing resources
In our previous work [4,5], we proposed a motion compensation based anti-shake mechanism for mobile display
We propose three simplified methods, including a Haar-like feature based method [6,7], a 2D logarithmic search method [8] and a Hough circle algorithm [9] based method
Summary
Visual tracking [1,2,3] has been an important research topic and gains increasing attention due to popular distribution of camera systems, visual tracking techniques are still time consuming and take a lot of computing resources. To improve the anti-shake performance, it is necessary to develop visual tracking functions on mobile devices. We propose three simplified methods, including a Haar-like feature based method [6,7], a 2D logarithmic search method [8] and a Hough circle algorithm [9] based method. All of these methods can serve for motion analysis and can be combined into our display stabilization mechanism to improve the anti-shake performance. 2) define a new searching region with half of the previous size and centered at the location found in step 1
