In this paper, we present a robust vision-based autonomous tracking of vehicle taillights and signal detection. In this study, the vehicle candidates are detected by Harr-like based classifier in bright scene and paired rear lights in dark scene, and this provides the taillight ROI for alert signal analysis. Then, the detected ROI regions are tracked with kernelized correlation filter. To recognize...
This paper proposes a new wearable eye-gaze tracking system with a single webcam mounted on the glasses. First, the region of interest (ROI) of eye is extracted by skin detection and eyelid removing. Then Hough circle detection is used to search the candidate of circles in the eye's ROI and applied to determine the status of opening or closing of eye. Based on the circle detection, the eye center...
This paper presents an effective traffic surveillance system for detecting and tracking moving vehicles in nighttime traffic scenes. The proposed method identifies vehicles by detecting and locating vehicle headlights and taillights using image segmentation and pattern analysis techniques. First, a fast bright-object segmentation process based on automatic multilevel histogram thresholding is applied...
