In this paper, we propose a new concept to integrate the conventional image segmentation techniques in order to accomplish the reasonable segmentation results. First, we develop an automatic seed selection algorithm using histogram for both scale and color vector. And the luminance and chrominance are utilized in the image as a guidance to optimize the(More)
—This paper presents a fast algorithm to detect the road lines and the road edges of structured and unstructured roads, respectively. In structured road detection, we firstly utilize vertical Sobel mask and color characteristic to detect the points of road lines. If the number of points is greater than a predefined threshold, we refine the detection results(More)
This paper proposes a new approach for global motion estimation using recursive algorithm in the sparsely sampled field, as well as we process parametric estimation in framework of one stage not in proposed pyramid structure. Firstly, we divide the image into blocks and obtain the highest gradient magnitude in each block to form a sparsely sampled field.(More)
This paper presents a method which detects the situation of car dangerous driving by video information. We estimate the parameters of global motion from the real-time video of vehicle driving, and analyze the variation of parameters for detection the dangerous status of driving. Firstly, we utilize global motion estimation to obtain the parameters of(More)
This paper presents an architecture for information capture and analysis of sitting posture using force sensor. We utilize force sensor and microcontroller to build a system for force information. We fix positions of force sensors on seat cushions firstly. Then, we design the circuits on microcontroller and obtain the data from sensors. There are different(More)
This paper proposes a fast road signs recognition framework with shape filtering and contour features. We observe the standard road signs and construct two basic feature tables for recognition processing. In road driving images, we transfer the RGB color domain to HSV for the red regions detection firstly. And we obtain candidate regions and decide the(More)
—In this paper, we propose various shot change detection models using spatial and temporal features. First, the short-term and long-term variations are discussed for the video shot change. Then, various robust shot change detection models are developed for detecting abrupt and gradual transitions. The residual image, frame difference and the motion(More)
