The goal of visual tracking is to estimate the location of the visual target in a sequence of images. If the video has long-term sequence of images, the tracking task without prior information is severely difficult due to the occlusion or the disappearance. Recently, tracking-by-detection methods have been proposed to solve the long-term tracking problem. However, most of them also suffer from drifting,...
This paper proposed robust object tracking using error filter. Proposed method consists of four steps: i) execution of tracking algorithm based on key point, ii) estimation of key point using error filter, iii) selection of key point as filtering outliers using Random Sample Consensus (RANSAC), and determination of object movement. The proposed method can track when object is occluded, abruptly change...
This paper presents a robust hand detection algorithm using the facial information. The proposed algorithm consists of four steps: (i) detection of a face, (ii) generation of regions of interest (ROI) to detect hands, (iii) skin color extraction from the face region, and (iv) detection of hands using the face skin color in the ROI. The proposed algorithm can reduce false detection caused by a similar...
This paper proposes a 3D path tracking method for a class of torpedo-type AUVs (autonomous underwater vehicles) with general form of dynamics. For this kind of AUV, there are only three control inputs are available for its 6DOF 3D motion, and therefore it's a typical underactuated system. First, we introduce certain two spherical coordinate transformations so as to transform the vehicle model into...
