We have developed a dynamic hand gesture recognition system that can simplify the way humans interact with computers and many other non-critical consumer electronic equipment. The proposed system is based on the well-known “Wave Controller” technology developed at the University of Wollongong and will revolutionize video gaming and consumer electronics control interfaces. Currently,...
This paper at first presents a novel approach to recognize characters, numbers or the signs under translation, scaling and rotation (TRS) from Civil Aerial Meteorological Maps by templates, which is based on a new class of moment invariants. Meanwhile, aiming to the important parameter (the range of orders for moment invariants) in it, we prove so that could decrease efficiently the errors brought...
The moment descriptor is combined with Gaussian curvature for three-dimensional shape representation and a novel three-dimensional shape descriptor combined local with global representations is proposed in this paper. Normalization process to the new moment invariants is presented and their independence to the translation, rotation and scaling transforms is proved. Experiments indicate a better classification...
Autonomous navigation is seen as a vital tool in harnessing the enormous potential of unmanned aerial vehicles (UAV) and small robotic vehicles for both military and civilian use. Even though, laser based scanning solutions for simultaneous location and mapping (SLAM) is considered as the most reliable for depth estimation, they are not feasible for use in UAV and land-based small vehicles due to...
Micrographs of Chinese wines show floccule, stick and granule of variant shape and size. Different wines have variant microstructure and micrographs, we study the classification of Chinese wines based on the micrographs. In this work, ten Chinese wines are determined or classified in the system, such as Wuliangye, Luzhoulaojiao, Xushui, Jiannanchun, Maotai and et.al. For each wine, we collect micrographs...
This paper introduces a general purpose graphics processing unit (GPGPU) stream processing implementation of moment invariants using an integral image or summed area table approach. Summed area tables have been used to help attain real-time performance for some classifier systems, however due to the computational complexity of moment invariants, a high throughput computational platform is required...
