(English Abstract)
Due to the recent growth of mobile market, the need for descriptors that are fast and yet robust to rotation, scale and affine transformations is increasing. In this paper we propose a new binary descriptor based on layered structure patterns for object recognition and pose estimation. Recently proposed binary descriptors such as FREAK and BRISK shows similar performance as the SIFT-like descriptors and yet has greatly enhanced the processing speed. In this paper, we propose a new binary descriptor based on layered structure patterns that maintains the existing framework, and also a method to estimate the dominant orientation that is robust to variations. The proposed descriptors were tested on a database(KAIST-DB) that includes illumination, scale, rotation and affine variation. The results showed that it works in real time with better and more stable performance than recently proposed binary descriptors.
