Abstract

Mobile markerless augmented reality (AR) requires a descriptor that can act in real time and at the same time robust to illumination invariance. Several color descriptors have been proposed to increase illumination invariance such as RGB-SIFT. According to the previous study, FREAK descriptor has been identified as the most suitable descriptor for mobile markerless AR due to FREAK reviews less computation time compared to other descriptors. However, color information presents important information has been largely ignored by FREAK. Hence, this research proposed a new illumination invariant feature based on FREAK descriptor in RGB color space for mobile markerless AR. Red, green and blue color channel will applied separately to FREAK descriptor. Hence, there are four types of descriptor been introduce; Red-FREAK, Green-FREAK, Blue-FREAK and RGB-FREAK. The proposed color FREAK descriptors are evaluated using images of different illumination color from Amsterdam Library of Object Images data set. The results show that the proposed color FREAK descriptors have enhanced the accuracy under illumination invariance for mobile markerless AR.
