Keynote: Hexagonal Structure For Intelligent Vision, Xiangjian He, Wenjing Jia
Keynote: Hexagonal Structure For Intelligent Vision, Xiangjian He, Wenjing Jia
International Conference on Information and Communication Technologies
Using hexagonal grids to represent digital images have been studied for more than 40 years. Increased processing capabilities of graphic devices and recent improvements in CCD technology have made hexagonal sampling attractive for practical applications and brought new interests on this topic. The hexagonal structure is considered to be preferable to the rectangular structure due to its higher sampling efficiency, consistent connectivity and higher angular resolution and is even proved to be superior to square structure in many applications. Since there is no mature hardware for hexagonal-based image capture and display, square to hexagonal image conversion has to be done …
