A new low-complexity patch-based image super-resolution
Anbarjafari, Gholamreza; Rasti, Pejman; Nasrollahi, Kamal; Orlova, Olga; Tamberg, Gert; Ozcinar, Cagri; Moeslund, Thomas B. (INST ENGINEERING TECHNOLOGY-IET, 2017-10)In this study, a novel single image super-resolution (SR) method, which uses a generated dictionary from pairs of high-resolution (HR) images and their corresponding low-resolution (LR) representations, is proposed. First, ... -
Reducible dictionaries for single image super-resolution based on patch matching and mean shifting
Anbarjafari, Gholamreza; Rasti, Pejman; Nasrollahi, Kamal; Orlova, Olga; Tamberg, Gert; Moeslund, Thomas B. (IS&T & SPIE, 2017-03)A single-image super-resolution (SR) method is proposed. The proposed method uses a generated dictionary from pairs of high resolution (HR) images and their corresponding low resolution (LR) representations. First, HR ... -
A Robust Color Image Watermarking Scheme Using Entropy and QR Decomposition
Anbarjafari, Gholamreza; Laur, Lauri; Rasti, Pejman; Agoyi, Mary (SPOLECNOST PRO RADIOELEKTRONICKE INZENYRSTVI, 2015-12)Internet has affected our everyday life drastically. Expansive volumes of information are exchanged over the Internet consistently which causes numerous security concerns. Issues like content identification, document and ... -
Robust non-blind color video watermarking using QR decomposition and entropy analysis
Anbarjafari, Gholamreza; Rasti, Pejman; Samiei, Salma; Agoyi, Mary; Escalera, Sergio (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2016-07)Issues such as content identification, document and image security, audience measurement, ownership and copyright among others can be settled by the use of digital watermarking. Many recent video watermarking methods show ... -
Satellite image enhancement: systematic approach for denoising and resolution enhancement
Anbarjafari, Gholamreza; Rasti, Pejman; Tasmaz, Haci; Daneshmand, Morteza; Kiefer, Rudolf (FEDERACION ASOCIACIONES INGENIEROS INDUSTRIALES ESPANA, 2016-05)This paper proposes a satellite image enhancement system consisting of denoising and resolution enhancement. The technique firstly decomposes the noisy input image into different frequency subbands by using Dual Tree Complex ... -
Statistical approach based iris recognition using local binary pattern
Anbarjafari, Gholamreza; Rasti, Pejman; Daneshmand, Morteza (FEDERACION ASOCIACIONES INGENIEROS INDUSTRIALES ESPANA, 2017-01)Among biometric features utilized for identity recognition purposes, iris has proven to be the most reliable one in terms of sufficient distinctiveness, which has direct implications and importance towards improving the ...
