MetaVIn: Atmospheric Turbulence Strength Estimation
Invention Description Long-range image analysis presents a significant challenge in computer vision, primarily due to atmospheric turbulence. The spatiotemporal variation in the medium's refractive index causes light ray bending, resulting in image degradation, specifically blurring and geometric deformation. Traditional estimation methods for...

Unsupervised Region-Growing Network for Object Segmentation in Atmospheric Turbulence
Background Foreground and background segmentation is an important part of computer vision tasks including surveillance, remote sensing, and environmental monitoring. However, in long-range imaging for outdoor environments, substantial image distortions can occur due to atmospheric turbulence. These distortions limit the effectiveness of segmentation...
