This paper develops a Bayesian retinex algorithm for enhancing single underwater image
with multiorder gradient priors of reflectance and illumination. First, a simple yet effective …

A wide range of human–robot collaborative applications in diverse domains, such as
manufacturing, health care, the entertainment industry, and social interactions, require an …

This letter explores the design and development of a class of robust diver detection
algorithms for autonomous diver-following applications. By considering the operational …

In this paper, we present a number of robust methodologies for an underwater robot to
visually detect, follow, and interact with a diver for collaborative task execution. We design …

Underwater operations present unique challenges and opportunities for robotic applications.
These can be attributed in part to limited sensing capabilities, and to locomotion behaviours …

We describe an interaction paradigm for controlling a robot using hand gestures. In
particular, we are interested in the control of an underwater robot by an on-site human …

In this article we present a new approach for object recognition in a robotic underwater
context. Color is an attractive feature because of its simplicity and its robustness to scale …

The Johnson-Lindenstrauss lemma shows that any set of n points in Euclidean space can
be mapped linearly down to O ((log n)//spl epsi//sup 2/) dimensions such that all pairwise …

We present an algorithm for underwater robots to track mobile targets, and specifically
human divers, by detecting periodic motion. Periodic motion is typically associated with …

This paper presents an approach for autonomous underwater robots to visually detect and
identify divers. The proposed approach enables an autonomous underwater robot to detect …
