Visual Odometry System Using Multiple Stereo Cameras and Inertial Measurement Unit
In this paper, we present a robust method that addresses these challenges using a human wearable system with two pairs of backward and forward looking stereo cameras together with an…

Precise Visual Navigation Using Multi-Stereo Vision and Landmark Matching
In this paper, we propose a set of techniques which greatly reduce the long term drift and also improve its robustness to many failure conditions.

On-The-Move Independently Moving Target Detection
This paper describes a system for automatically detecting potential targets (that pop-up or move into view) and to cue the operator to potential threats. We present a 3D approach for…

Preceding Vehicle Trajectory Prediction by Multi-Cue Integration
In this paper we describe an approach to detect and predict the driving trajectory of a preceding vehicle on highway. In particular, we focus on detecting and predicting the changing…

Segmentation of Aerial Surveillance Video Using a Mixture of Experts
We propose a video segmentation algorithm for aerial surveillance video. The algorithm uses a Mixture of Experts consisting of a supervised image segmentation algorithm named the Trainable Sequential MAP segmentation…

Towards a Practical Stereo Vision Sensor
This paper describes an experimental framework for determining these limits using image processing algorithms, operating on graphically synthesized imagery, with performance envelope validation on real stereo image data.

Stereo-Based Object Detection, Classification, and Quantitative Evaluation with Automotive Applications
A real-time stereo-based pre-crash object detection and classification system is presented. The system employs a model based stereo object detection algorithm to find candidate objects from the scene, followed by…

Unsupervised Learning of Discriminative Edge Measures for Vehicle Matching Between Non-Overlapping Cameras
This paper proposes a method for matching road vehicles between two non-overlapping cameras. The matching problem is formulated as a same-different classification problem: probability of two observations from two distinct…
-
Vehicle Fingerprinting for Reacquisition and Tracking in Videos
We address the problem of vehicle matching when multiple observations of a vehicle are separated in time such that frames of observations are not contiguous, thus prohibiting the use of…

Reference-Free Objective Quality Metrics for MPEG-Coded Video
In this paper, we propose a reference-free video quality metric for MPEG coded videos. It predicts subjective quality ratings using both reference-free MPEG artifact measures and MPEG system parameters (known…
-
Visual Odometry
We present a system that estimates the motion of a stereo head or a single moving camera based on video input.

Stereo-Based Vision System for Automotive Imminent Collision Detection
In this paper, we demonstrate that stereo vision is a promising solution to this problem. Our prototype system has been rigorously tested for different colliding scenarios (e.g., different intersection angles…
