This study addresses the automatic multi-person tracking problem in complex scenes from a single, static, uncalibrated camera. In contrast with offline tracking approaches, a novel online multi-person tracking method is proposed based on a sequential tracking-by-detection framework, which can be applied to real-time applications. A two-stage data association is first developed to handle the drifting...
Online multi-object tracking is one of the crucial tasks in time-critical computer vision applications. In this paper, the problem of online multi-object tracking in complex scenes from a single, static, un-calibrated camera is addressed. In complex scenes, it is still challenging due to frequent and prolonged occlusions, abrupt motion change of objects, unreliable detections, and so on. To handle...
In this paper, we propose a novel image segmentation algorithm for license plate recognition (LPR) in video based traffic surveillance system. The license plate character segmentation is most important procedure in LPR system. However, in real situation, the character segmentation algorithms are challenged by drastic performance decrease due to sudden local illumination changes, especially when the...
An accelerometer embedded wrist-worn device is widely used for sleep assessment. However, conventional methods determine a state of user to "sleep" or "wakefulness" according to whether the accelerometer value of individual epoch exceeds a certain threshold or not. As a result, high miss-classification rate is observed due to user's small intermittent movements while sleeping and...
An efficient protocol for the solid-phase synthesis of 2,4-disubstituted 5-carbamoyl-thiazole derivatives has been developed. After the reaction scopes were investigated in solution-phase, the polymer-supported synthesis route was progressed using a sulfide linker in a traceless manner. The solid-phase synthetic protocol started with the Thorpe-Ziegler type cyclization of 2-chloroacetamide and polymer-bound...
This paper presents a novel online multi-person tracking method based on tracking-by-detection framework for intelligent video surveillance systems consisting of an internet protocol (IP) camera and a network video recorder (NVR). First, the two-step data association based on high/low confidence targets is proposed for handling long-term occlusions effectively. Additionally, the method that reasons...
