An Approximate Spectral Clustering Ensemble for High Spatial Resolution Remote-Sensing Images
Tasdemir, Kadim; Yildirim, Isa; Moazzen, Yaser (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2015)Unsupervised clustering of high spatial resolution remote-sensing images plays a significant role in detailed landcover identification, especially for agricultural and environmental monitoring. A recently promising method ... -
Implementation of Majorization-Minimization (MM) Algorithm for 3D Total Variation Minimization in DBT Image Reconstruction
Polat, Adem; Matela, Nuno; Mota, Ana Margarida; Yildirim, Isa (IEEE, 2016)Digital Breast Tomosynthesis (DBT) is a developing imaging modality which produces 3D images of a breast. Iterative image reconstruction techniques, such as Algebraic reconstruction technique (ART), have been proposed to ... -
Iterative image reconstruction using non-local means with total variation from insufficient projection data
Ertas, Metin; Yildirim, Isa; Kamasak, Mustafa; Akan, Aydin (IOS PRESSNIEUWE HEMWEG 6B, 1013 BG AMSTERDAM, NETHERLANDS, 2016)In this work, algebraic reconstruction technique (ART) is extended by using non-local means (NLM) and total variation (TV) for reduction of artifacts that are due to insufficient projection data. TV and NLM algorithms use ...
