A Novel Algorithm for Digital Lithological Mapping-Case Studies in Sri Lanka's Mineral Exploration

no code implementations1 Apr 2024 R. M. L. S. Ramanayake, D. Fernando, D. Wickramasinghe, D. Y. L. Ranasinghe, G. M. R. I. Godaliyadda, H. M. V. R. Herath, M. P. B. Ekanayake, A. Senaratne, Fadi Kizel

The results of satellite-based spectral imaging analysis were corroborated with X-ray diffraction (XRD) and Magnetic Separation (MS) analysis of soil samples collected from those sites via field surveys.

Transformer based Endmember Fusion with Spatial Context for Hyperspectral Unmixing

no code implementations6 Feb 2024 H. M. K. D. Wickramathilaka, R. M. K. L. Ratnayake, D. M. U. P. Sumanasekara, G. M. R. I. Godaliyadda, M. P. B. Ekanayake, H. M. V. R. Herath

Drawing inspiration from this, we propose a novel attention based Hyperspectral Unmixing algorithm called Transformer based Endmember Fusion with Spatial Context for Hyperspectral Unmixing (FusionNet).

Dual mode multispectral imaging system for food and agricultural product quality estimation

no code implementations4 Oct 2023 Darsha Udayanga, Ashan Serasinghe, Supun Dassanayake, Roshan Godaliyadda, H. M. V. R. Herath, M. P. B. Ekanayake, H. L. P. Malshan

An innovative merged mode is introduced in which both reflectance and transmittance information of a specimen are combined to form a higher dimensional dataset with more features.

Transmittance Multispectral Imaging for Reheated Coconut Oil Differentiation

no code implementations28 Aug 2021 D. Y. L. Ranasinghe, H. M. H. K. Weerasooriya, S. Herath, M. P. B. Ekanayake, H. M. V. R. Herath, G. M. R. I. Godaliyadda, T. Madhujith

Accordingly, the proposed work closes the gap for using multispectral imaging for oil reheating and proposes a novel algorithm for unsupervised detection of critical property changes in the oil.

Quantitative Assessment of Adulteration and Reuse of Coconut Oil Using Transmittance Multispectral Imaging

no code implementations30 Nov 2020 S. Herath, H. K. Weerasooriya, D. Y. L. Ranasinghe, W. G. C. Bandara, H. M. V. R. Herath, G. M. R. I. Godaliyadda, M. P. B. Ekanayake, Terrence Madhujith

Therefore, we propose an imaging system hardware and image processing-based algorithm to estimate the adulteration of coconut oil with palm oil as the adulterant.

Constrained Nonnegative Matrix Factorization for Blind Hyperspectral Unmixing incorporating Endmember Independence

no code implementations2 Mar 2020 E. M. M. B. Ekanayake, H. M. H. K. Weerasooriya, D. Y. L. Ranasinghe, S. Herath, B. Rathnayake, G. M. R. I. Godaliyadda, M. P. B. Ekanayake, H. M. V. R. Herath

Hyperspectral unmixing (HU) has become an important technique in exploiting hyperspectral data since it decomposes a mixed pixel into a collection of endmembers weighted by fractional abundances.
