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,...
A sign language is a language which, instead of acoustically conveyed sound patterns, uses visually transmitted sign patterns. Sign languages are commonly developed for deaf communities, which can include interpreters, friends and families of deaf people as well as people who are deaf or hard of hearing themselves. Developing a sign language recognition system will help the hearing impaired to communicate...
SAR (synthetic aperture radar) image tracking is one of the key technologies of MMW(millimetre wave) imaging missile guider. Due to the restriction of missile-borne imaging conditions such as vibration, rolling and yawing, traditional tracking algorithm with NPROD(normalized production) correlation is difficult to adapt deformations such as rotation and scaling between target image segmented from...
Image feature extraction is the most important aspect of content-based image retrieval. This paper presents a method for shape-based feature extraction of high resolution remote sensing image. Firstly the edges in the original image are detected according to Smallest Univalue Segment Assimilating Nucleus (SUSAN) principle. Then, the moment invariants of the edge map are calculated, and the result...
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...
