2018 25th IEEE International Conference on Image Processing (ICIP), 2018
The goal of this paper is to estimate the population of fishes in sonar images. Compared to natural images, sonar images present substantially different visual characteristics. Fishes in sonar images exhibit unreliable appearance cues, expose under imaging noise, vary significantly in shape and size.

Denoising and inpainting SONAR images
2015 38th International Conference on Telecommunications and Signal Processing (TSP), 2015The basic principle of SONAR is to use sound to detect or locate objects, typically in the ocean. During acquisition, some pixels of SONAR images could be lost. The recovery of lost or damaged data can be done by using an inpainting algorithm. But, SONAR images are perturbed by speckle noise, so speckle reduction filters should be used to improve the ...

Synthetic aperture active sonar imaging
[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992The main problems involved in synthetic aperture sonar imaging are medium instability, slow mapping rate, and platform motion. Proposed solutions to these problems are reviewed, and a new technique for synthetic aperture sonar imaging is presented which allows a fast mapping rate and improved motion compensation.

An Adaptive Denoising and Detection Approach for Underwater Sonar Image
Remote Sensing, 2019 An adaptive approach is proposed to denoise and detect the underwater sonar image in this paper. Firstly, to improve the denoising performance of non-local spatial information in the underwater sonar image, an adaptive non-local spatial information ...

Unsupervised Markovian segmentation of sonar images
1997 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2002This work deals with unsupervised sonar image segmentation. We present a new estimation segmentation procedure using the an iterative method called iterative conditional estimation (ICE). This method takes into account the variety of the laws in the distribution mixture of a sonar image and the estimation of the parameters of the label field (modeled ...

Prior work dealing with optical imaging of sound waves was devoted to nondestructive testing applications at sound frequencies of 1 MHz and higher. Bragg diffraction of light by sound waves permits one to obtain optical images of sound fields on a real time basis.
