Modelling, Stack and Imaging: Marine Seismics

10th International Congress of the Brazilian Geophysical Society, 2007
This paper summarizes practical aspects of seismic modelling of a marine geological ambient of petroleum exploration of passive sedimentary basins along the Brazilian coast. The results of a consistent attention to stack and imaging demonstrate the basics and the potential of the combined SU/WIT processing systems.

Mariner 1969 television image processing

Pattern Recognition, 1970
Abstract Mariners 6 and 7 sent back approximately two hundred photographs of Mars, taken from distances ranging between one million and three thousand km relative to the planet surface. These images contain true object space information distorted, to one extent or another, by the signature of the imaging system itself.

Automatic detection of seafloor marine litter using towed camera images and deep learning.

Marine Pollution Bulletin, 2021
Aerial and underwater imaging is being widely used for monitoring litter objects found at the sea surface, beaches and seafloor. However, litter monitoring requires a considerable amount of human effort, indicating the need for automatic and cost ...

Towards image-based marine habitat classification

OCEANS 2008, 2008
It is now fairly routine to quasi-automatically generate acoustic bathymetry and optical mosaics from properly instrumented Autonomous Underwater Vehicles (AUVs). However, further analysis and interpretation of gathered data is needed to address tasks such as habitat characterization and monitoring.

Mariner 9—Image processing and products

Icarus, 1973
The purpose of this paper is to describe the system for the display, processing, and production of image-data products created to support the Mariner 9 Television Experiment. Of necessity, the system was large in order to respond to the needs of a large team of scientists with a broad scope of experimental objectives.

Digital Holographic Imaging of Marine Plankton

Applied Mechanics and Materials, 2012
Designing an advanced method to sensing marine plankton effectively is highly demanded for acquiring critical marine plankton information data. The goal of this paper is to use digital holographic imaging for sensing marine plankton in recording sampling volume with several advantages such as non-intrusive and non-destructive interrogation of the ...

A content based image retrieval system for marine life images

2011 IEEE 15th International Symposium on Consumer Electronics (ISCE), 2011
Malaysia has been recognized as one of the twelve nations endowed with rich biodiversity. Such huge number of species in the rain forest and sea are an important asset that need to be properly documented. Responding to these important needs, we have designed and evaluated a content based image retrieval system catered for marine life images. This paper

Simple and rapid detection of microplastics in seawater using hyperspectral imaging technology.

Analytica Chimica Acta, 2019
Microplastics (MPs) pollution in marine systems is attracting worldwide attentions, which highlights a pressing need for efficient detection methods. Traditional protocols generally identify the suspected particles individually, which are time-consuming.
