Model for Estimation of Bounds in Digital Coding of Seabed Images [PDF]

open access: yes, 2015
This paper proposes the novel model for estimation of bounds in digital coding of images. Entropy coding of images is exploited to measure the useful information content of the data.

Towards Terrain-Based Navigation Using Side-Scan Sonar

open access: yes2023 26th International Conference on Information Fusion (FUSION), 2023
This paper introduces a statistical model and corresponding sequential Bayesian estimation method for terrain-based navigation using side-scan sonar (SSS) data. The presented approach relies on slant range measurements extracted from the received ping of a SSS. In particular, incorporating slant range measurements to landmarks for navigation constrains

Modular Autonomous Biosampler (MAB)- A prototype system for distinct biological size-class sampling and preservation [PDF]

open access: yes, 2012
Presently, there is a community wide deficiency in our ability to collect and preserve multiple size-class biologic samples across a broad spectrum of oceanographic platforms (e.g. AUVs, ROVs, and Ocean Observing System Nodes).
