SONAR

ouvirOUver, 2020
As composições sonoro-visuais de O Grivo possibilitam múltiplas experiências numa relação entre música, instalação e performance. As esculturas sonoras inventadas pelos artistas, a partir de fragmentos, impressionam não só pelas formas, mas também pela presença que assumem no espaço, criando uma territorialidade expansiva que transita entre a gambiarra

A blind contour‐aware quality model for sonar images

IET Image Processing, 2022
Since the penetration depth of visible light is limited in muddy and dark deep marine environment, sonar imaging, which is independent of natural light, has been attracting much attention in underwater detections.

Small-Sample Sonar Image Classification Based on Deep Learning

Journal of Marine Science and Engineering, 2022
Deep learning is a core technology for sonar image classification. However, owing to the cost of sampling, a lack of data for sonar image classification impedes the training and deployment of classifiers. Classic deep learning models such as AlexNet, VGG,

Vertical dimension acoustic field interference pattern prediction and source depth estimation in deep ocean [PDF]

JASA Express Letters
In this Letter, a simplified expression of the vertical dimension narrowband interference pattern in deep water direct arrival zone is theoretically derived. The correlation between the vertical dimension interference pattern and source depth is analyzed,
