This paper introduces a parallel processing scheme
using CPU and GPU for the mobile Augmented Reality
applications. Most of AR applications have to perform intensive
image processing algorithms to detect specified objects on which
virtual information is overlaid. The object detection generally
consists of a feature extraction module and a feature description
module. The proposed scheme distributes the feature extraction
module and the feature description module to CPU and GPU
respectively, and performs the modules in parallel. In
experimental results, the proposed scheme outperforms the CPU
only scheme and the sequential CPU-GPU execution scheme.
