Enhancement of Underwater Video Mosaics for Post-Processing [PDF]

open access: yes, 2007
Mosaics of seafloor created from still images or video acquired underwater have proved to be useful for construction of maps of forensic and archeological sites, species\u27 abundance estimates, habitat characterization, etc.

A new 3-D modelling method to extract subtransect dimensions from underwater videos [PDF]

open access: yes, 2012
Underwater video transects have become a common tool for quantitative analysis of the seafloor. However a major difficulty remains in the accurate determination of the area surveyed as underwater navigation can be unreliable and image scaling does not ...

Underwater image quality enhancement of sea cucumbers based on improved histogram equalization and wavelet transform

open access: yesInformation Processing in Agriculture, 2017
Sea cucumbers usually live in an environment where lighting and visibility are generally not controllable, which cause the underwater image of sea cucumbers to be distorted, blurred, and severely attenuated.

Single underwater image enhancement based on adaptive correction of channel differential and fusion

open access: yesFrontiers in Marine Science, 2023
Clear underwater images are necessary in many underwater applications, while absorption, scattering, and different water conditions will lead to blurring and different color deviations.
