Estimating Solar Irradiance Using Sky Imagers
Soumyabrata Dev, Florian M. Savoy, Yee Hui Lee +1
Ground-based whole sky cameras are extensively used for localized monitoring of clouds nowadays. They capture hemispherical images of the sky at regular intervals using a fisheye l…
High-Dynamic-Range Imaging for Cloud Segmentation
Soumyabrata Dev, Florian M. Savoy, Yee Hui Lee +1
Sky/cloud images obtained from ground-based sky-cameras are usually captured using a fish-eye lens with a wide field of view. However, the sky exhibits a large dynamic range in ter…
Nighttime sky/cloud image segmentation
Soumyabrata Dev, Florian M. Savoy, Yee Hui Lee +1
Imaging the atmosphere using ground-based sky cameras is a popular approach to study various atmospheric phenomena. However, it usually focuses on the daytime. Nighttime sky/cloud…
Design of low-cost, compact and weather-proof whole sky imagers for high-dynamic-range captures
Soumyabrata Dev, Florian M. Savoy, Yee Hui Lee +1
Ground-based whole sky imagers are popular for monitoring cloud formations, which is necessary for various applications. We present two new Wide Angle High-Resolution Sky Imaging S…
Rough Set Based Color Channel Selection
Soumyabrata Dev, Florian M. Savoy, Yee Hui Lee +1
Color channel selection is essential for accurate segmentation of sky and clouds in images obtained from ground-based sky cameras. Most prior works in cloud segmentation use thresh…
Short-term prediction of localized cloud motion using ground-based sky imagers
Soumyabrata Dev, Florian M. Savoy, Yee Hui Lee +1
Fine-scale short-term cloud motion prediction is needed for several applications, including solar energy generation and satellite communications. In tropical regions such as Singap…
Estimation of solar irradiance using ground-based whole sky imagers
Soumyabrata Dev, Florian M. Savoy, Yee Hui Lee +1
Ground-based whole sky imagers (WSIs) can provide localized images of the sky of high temporal and spatial resolution, which permits fine-grained cloud observation. In this paper,…
WAHRSIS: A Low-cost, High-resolution Whole Sky Imager With Near-Infrared Capabilities
Soumyabrata Dev, Florian M. Savoy, Yee Hui Lee +1
Cloud imaging using ground-based whole sky imagers is essential for a fine-grained understanding of the effects of cloud formations, which can be useful in many applications. Some…
