Wearable tactile navigation system
John Zelek,Marc Holbein +1 more
TL;DR: The wearable tactile navigation system as mentioned in this paper is a wayfinding device for people that are blind and for people with Alzheimer's disease, which can provide geographical information in tactile form as opposed to providing it in visual or auditory form.
Journal ArticleDOI
Keyframe-based monocular SLAM
TL;DR: This paper presents a survey that covers the various keyframe-based monocular SLAM systems in the literature, detailing the components of their implementation, and critically assessing the specific strategies made in each proposed solution.

Statistical Textural Distinctiveness for Salient Region Detection in Natural Images
TL;DR: Experimental results show that the proposed statistical textural distinctiveness approach for robustly detecting salient regions in natural images provides interesting and promising results when compared to existing saliency detection methods.
Journal ArticleDOI
Goal-based trajectory analysis for unusual behaviour detection in intelligent surveillance
TL;DR: The proposed method extends the original goal-based approach in three ways: first, the spatial scene structure is learned in a training phase; second, a region transition model is learned to describe normal movement patterns between spatial regions; and third, classification of trajectories in progress is performed in a probabilistic framework using particle filtering.
Journal ArticleDOI
An Expert System for Remote Sensing
TL;DR: The Canada Centre for Remote Sensing has developed two hierarchical expert systems, the Analyst Advisor and the Map Image Congruency Evaluation (MICE) advisor, built upon the Remote-Sensing Shell written in Logicware's MPROLOG.
