Autor: Mads Nibe Larsen, Anders Løchte Jørgensen, Victor Petrunin, Jakob Kjelstrup-Hansen, Bjarke Jørgensen, Mogens Hinge
Publikováno v: Polymer Testing, Vol 141, Iss , Pp 108629- (2024)
Identification of black plastics poses a significant challenge in recycling due to the absorptive nature of carbon black additives. This work introduces a method where hyperspectral imaging in the long-wave infrared regime is used to distinguish betw

Materials and technology of mosaics from the House of Charidemos at Halikarnassos (Bodrum, Turkey)
Autor: Kaare Lund Rasmussen, Thomas Delbey, Bjarke Jørgensen, Kasper Høegh Jensen, Birte Poulsen, Poul Pedersen
Publikováno v: Heritage Science, Vol 10, Iss 1, Pp 1-23 (2022)
Abstract An excavation in 1856 by Charles T. Newton and a re-excavation in 1990–93 by a joint Danish-Turkish team revealed several mosaic floors in a late-antique domus from the fifth century CE, now called the House of Charidemos. Nineteen tessera

The hybrid approach—convolutional neural networks and expectation maximisation algorithm—for tomographic reconstruction of hyperspectral images
Autor: Bjarke Jørgensen, René Eriksen, Mads Frandsen, Wei-Chih Huang, Mads Peters, Mads Ahlebæk
Publikováno v: Journal of Spectral Imaging.
We present a simple, but novel, hybrid approach to hyperspectral data cube reconstruction from computed tomography imaging spectrometry (CTIS) images that sequentially combines neural networks and the iterative expectation maximisation (EM) algorithm
