Underwater Object Detection Using Image Processing
2021This project describes the architecture and design of an improved configurable underwater object detection using image processing. The vision based method for detecting the objects under water is carried out using Yolo based convolutional neural network (CNN). YOLO (You Only Look Once) is a real time object detection algorithm. This algorithm applies a

Image processing of underwater multispectral imagery
IEEE Journal of Oceanic Engineering, 2003Capturing in situ fluorescence images of marine organisms presents many technical challenges. The effects of the medium, as well as the particles and organisms within it, are intermixed with the desired signal. Methods for extracting and preparing the imagery for analysis are discussed in reference to a novel underwater imaging system called the low ...

Localization of autonomous underwater vehicles by sonar image processing
ELMAR 2007, 2007A major percentage of underwater operations takes place in structured enviroments. This article presents a low cost way for underwater vehicle positionig in places like pools, tanks, water towers etc. The developed application calculates a 2D position using only a simple scanning sonar and a digital compass. An user interface has also been designed for

Enhancing Underwater Image Quality through Image Processing
Underwater images find application in various fields, like marine research, inspection of aquatic habitat, underwater surveillance, identification of minerals, and more. Longer wavelengths are absorbed by water at greater depths. Due to the greater wavelength, red is absorbed and the images seem primarily bluish-green. Images suffer greatly as a resultMamatha, R. +4 more

Image processing techniques for underwater acoustic image enhancement
The Journal of the Acoustical Society of America, 2003Underwater acoustic images are often dominated by noise, which obscures signals of interest. When the spatial character of the noise differs from that of the signal, image processing techniques can be employed to enhance the image. In underwater acoustic time-bearing displays, the signals of interest form continuous tracks, while noise often takes on ...

Acoustic PPM image processing for underwater communications
OCEANS 2011 IEEE - Spain, 2011Pulse position modulated (PPM) acoustic pulses are difficult to detect since they carry information on delays so, assuring reliable information delivery mainly in shallow sea channels because of strong multipath and other interference sources/causes, large signal fluctuation and high noise level may be considered a timely challenge. This paper proposes

Image processing for underwater measurement of salmon biomass
IEE Colloquium on Underwater Applications of Image Processing, 1998A non-intrusive method for monitoring salmon stock has been developed which includes the use of two matched monochrome CCD cameras. Stereo image sequences are grabbed and digitised. The images are used to calculate various measurements from the fish, which are then used to estimate its mass.

Three-dimensional underwater acoustical imaging and processing
2002Acoustic imaging is an active research field that aims to study techniques for the formation and processing of images generated by raw signals acquired by an acoustic system [1]. Our purpose is to present a brief survey concerning the generation and processing of acoustic images for underwater applications [2,3], especially focusing on algorithms for ...
