(MDPI AG, 2017-03-17)Aerial image classification has become popular and has attracted extensive research efforts in recent decades. The main challenge lies in its very high spatial resolution but relatively insufficient spectral information. To this end, spatial-spectral ... -
(2016-03-02)Inngangur: Magakrabbamein var algengasta krabbameinið á Íslandi upp úr miðri 20. öld en er nú einungis 2-3% krabbameina. Markmið þessarar rannsóknar var að gera faraldsfræðilegan samanburð á tveimur meginflokkum kirtilfrumukrabbameina í maga samkvæmt ...

(MDPI AG, 2019-01-10)In this paper, we develop a hyperspectral feature extraction method called sparse and smooth low-rank analysis (SSLRA). First, we propose a new low-rank model for hyperspectral images (HSIs) where we decompose the HSI into smooth and sparse components. ...

(MDPI AG, 2020-04-07)This paper proposes three feature extraction (FE) methods based on density estimation for hyperspectral images (HSIs). The methods are a mixture of factor analyzers (MFA), deep MFA (DMFA), and supervised MFA (SMFA). The MFA extends the Gaussian mixture ...
