Seafloor video mapping: modeling, algorithms, apparatus

Proceedings. International Conference on Image Processing, 2003
This paper discusses a technique used for construction of high-resolution image mosaic from a video sequence and the synchronously logged camera attitude information. It allows one to infer geometric characteristics of the imaged terrain and hence improve the mosaic quality and reduce the computational burden.

Seafloor Segmentation Based on Bathymetric Measurements from Multibeam Echosounders Data [PDF]

, 2003
Bathymetric data depicts the geomorphology of the seabottom and allows characterization of spatial distributions of apparent benthic habitats. The variability of seafloor topography can be defined as a texture.

Status of global seafloor mapping effort and priority areas for future mapping

Frontiers in Marine Science
Several global and regional initiatives exist to increase the proportion of seafloor mapped by direct measurements, brought together through international collaborations, of which the Nippon Foundation-GEBCO Seabed 2030 Project is perhaps the most well ...

Where, What, When, and Why Is Bottom Mapping Needed? An On-Line Application to Set Priorities Using Expert Opinion

Geosciences, 2018
Globally, there is a lack of resources to survey the vast seafloor areas in need of basic mapping data. Consequently, smaller areas must be prioritized to address the most urgent needs.

Sensor-assisted video mosaicing for seafloor mapping [PDF]

Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002
This paper discusses a proposed processing technique for combining video imagery with auxiliary sensor information. The latter greatly simplifies image processing by reducing complexity of the transformation model. The mosaics produced by this technique are adequate for many applications, in particular habitat mapping.
