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...

Neural Volumetric Reconstruction for Coherent Synthetic Aperture Sonar
Synthetic aperture sonar (SAS) is an active acoustic imaging technique that coherently combines data from a moving array to form high-resolution imagery, especially of underwater environments. The moving array in SAS collects both magnitude and phase information which allows coherent integration methods to achieve resolution parallel to the sensor...

MaRTiny- A Low Cost Bio-Meteorological Sensing Device with Embedded Computer Vision for Urban Climate Research
­Background The Earth recorded its largest surface temperature increase between the years of 2010 and 2020. The temperature increased by nearly 1.2°F over that period which resulted in the sixth highest surface temperature on record. In urban environments with large condensed populations, there is a growing need to examine the effects that...
