Computer Vision based group activity detection and action spotting
Narthana Sivalingam, Santhirarajah Sivasthigan, Thamayanthi Mahendranathan +3
Group activity detection in multi-person scenes is challenging due to complex human interactions, occlusions, and variations in appearance over time. This work presents a computer…
Enhanced SCanNet with CBAM and Dice Loss for Semantic Change Detection
Athulya Ratnayake, Buddhi Wijenayake, Praveen Sumanasekara +3
Semantic Change Detection (SCD) in remote sensing imagery requires accurately identifying land-cover changes across multi-temporal image pairs. Despite substantial advancements, in…
A Novel Algorithm for Digital Lithological Mapping-Case Studies in Sri Lanka's Mineral Exploration
R. M. L. S. Ramanayake, D. C. Dammage, I. Z. M. Zumri +8
Conventional manual lithological mapping (MLM) through field surveys are resource-extensive and time-consuming. Digital lithological mapping (DLM), harnessing remotely sensed spect…
Convolutional Autoencoder for Blind Hyperspectral Image Unmixing
Yasiru Ranasinghe, Sanjaya Herath, Kavinga Weerasooriya +4
In the remote sensing context spectral unmixing is a technique to decompose a mixed pixel into two fundamental representatives: endmembers and abundances. In this paper, a novel ar…
