Due to gesture recognition, smart TVs that are controlled by simple motions have been steadily developed and improved. Important problems, however, remain unresolved. In comparison to low-price remote controllers, it is difficult to achieve competitive prices and performances for diverse and complex gesture-recognition systems with the use of costly 3D motion sensors. This study therefore aims to...
This paper describes pipelined hardware architecture for real-time laser point position detection system by using FPGA. This system processes 640×480 resolution images that were received by the CCD camera. We detected the position of the laser point through the following 5 steps. First, the screen area is detected by Homography transform by using chess board. Second, the system converts the inputted...
Measuring a vehicle's speed using a video image is an important technique in an intelligent transportation system. This paper presents a hardware implemented vehicle speed measurement (VSM) system. The operation of the system consists of three steps. First, we remove vehicles from a series of captured images to create a background. To do this, we introduce a simplified exclusion algorithm optimized...
