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…
Detecting Rainfall Onset Using Sky Images
Soumyabrata Dev, Shilpa Manandhar, Yee Hui Lee +1
Ground-based sky cameras (popularly known as Whole Sky Imagers) are increasingly used now-a-days for continuous monitoring of the atmosphere. These imagers have higher temporal and…
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…
Color-based Segmentation of Sky/Cloud Images From Ground-based Cameras
Soumyabrata Dev, Yee Hui Lee, Stefan Winkler
Sky/cloud images captured by ground-based cameras (a.k.a. whole sky imagers) are increasingly used nowadays because of their applications in a number of fields, including climate m…
Machine Learning Techniques and Applications For Ground-based Image Analysis
Soumyabrata Dev, Bihan Wen, Yee Hui Lee +1
Ground-based whole sky cameras have opened up new opportunities for monitoring the earth's atmosphere. These cameras are an important complement to satellite images by providing ge…
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,…
