Anbarjafari, Gholamreza; Ofodile, Ikechukwu; Helmi, Ahmed; Clapes, Albert; Avots, Egils; Peensoo, Kerttu Maria; Valdma, Sandhra-Mirella; Valdmann, Andreas; Valtna-Lukner, Heli; Omelkov, Sergey; Escalera, Sergio; Ozcinar, Cagri (MDPI, 2019-04)Action recognition is a challenging task that plays an important role in many robotic systems, which highly depend on visual input feeds. However, due to privacy concerns, it is important to find a method which can recognise ... -
Adaptive multi-view video streaming using side information over peer-to-peer networks
Anbarjafari, Gholamreza; Ozcinar, Cagri; Ekmekcioglu, Erhan; Kondoz, Ahmet (SPRINGER, 2019-03)Multi-view plus-depth-map (MVD) video streaming with autostereoscopic displays provides multi-user immersive media experiences. In this context, delivery of MVD representation to multiple clients remains a challenging ... -
Correction to: Optimal image compression via block-based adaptive colour reduction with minimal contour effect (Multimedia Tools and Applications, (2018), 77, 23, (30939-30968), 10.1007/s11042-018-6118-y)
Rasti, Pejman; Lüsi, Iiris; Bolotnikova, Anastasia; Daneshmand, Morteza; Ozcinar, Cagri; Anbarjafari, Gholamreza (Springer, 2019)After the publication of this work [1], it was noticed that the co-author Pejman Rasti was omitted as the first author following an institutional investigation. The first author’s name is inserted in this erratum article. -
Cycle-consistent generative adversarial neural networks based low quality fingerprint enhancement
Karabulut, Doğuş; Tertychnyi, Pavlo; Arslan, Hasan Sait; Ozcinar, Cagri; Nasrollahi, Kamal; Valls, Joan; Vilaseca, Joan; Moeslund, Thomas Baltzer; Anbarjafari, Gholamreza (Springer, 1 July 202)Distortions such as dryness, wetness, blurriness, physical damages and presence of dots in fingerprints are a detriment to a good analysis of them. Even though fingerprint image enhancement is possible through physical ... -
Dynamic bitrate allocation of interactive real-time streamed multi-view video with view-switch prediction
Anbarjafari, Gholamreza; Ozcinar, Cagri (SPRINGER LONDON LTD, 2017-10)In multi-view video (MVV), the real-world scene is usually captured by more than two cameras positioned in an array. A viewer can consume MVV using either a non-interactive or an interactive transmission method. In the ... -
Ensemble Approach for Detection of Depression Using EEG Features
Avots, Egils; Jermakovs, Klavs; Bachmann, Maie; Paeske, Laura; Ozcinar, Cagri; Anbarjafari, Gholamreza (MDPI, FEB 2022)Depression is a public health issue that severely affects one's well being and can cause negative social and economic effects to society. To raise awareness of these problems, this research aims at determining whether the ... -
Ethical AI in facial expression analysis: racial bias
Sham, Abdallah Hussein; Aktas, Kadir; Rizhinashvili, Davit; Kuklianov, Danila; Alisinanoglu, Fatih; Ofodile, Ikechukwu; Ozcinar, Cagri; Anbarjafari, Gholamreza (SPRINGER LONDON LTD, MAY 2022)Facial expression recognition using deep neural networks has become very popular due to their successful performances. However, the datasets used during the development and testing of these methods lack a balanced distribution ... -
Image illumination enhancement with an objective no-reference measure of illumination assessment based on Gaussian distribution mapping
Anbarjafari, Gholamreza; Jafari, Adam; Jahromi, Mohammad Naser Sabet; Ozcinar, Cagri; Demirel, Hasan (ELSEVIER - DIVISION REED ELSEVIER INDIA PVT LTD, 2015-12)Illumination problems have been an important concern in many image processing applications. The pattern of the histogram on an image introduces meaningful features; hence within the process of illumination enhancement, it ... -
Imperceptible non-blind watermarking and robustness against tone mapping operation attacks for high dynamic range images
Anbarjafari, Gholamreza; Ozcinar, Cagri (SPRINGER, 2018-09)High dynamic range (HDR) imaging has experienced a widespread during the recent years through various technologies, including social network applications, which necessitates robust watermarking schemes to protect the ... -
Low-quality fingerprint classification using deep neural network
Anbarjafari, Gholamreza; Ozcinar, Cagri; Tertychnyi, Pavlo (INST ENGINEERING TECHNOLOGY-IET, 2018-11)Fingerprint recognition systems mainly use minutiae points information. As shown in many previous research works, fingerprint images do not always have good quality to be used by automatic fingerprint recognition systems. ... -
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, ... -
A novel deep network architecture for reconstructing RGB facial images from thermal for face recognition
Anbarjafari, Gholamreza; Litvin, Andre; Nasrollahi, Kamal; Escalera, Sergio; Ozcinar, Cagri; Moeslund, Thomas B. (Springer, 2019)This work proposes a fully convolutional network architecture for RGB face image generation from a given input thermal face image to be applied in face recognition scenarios. The proposed method is based on the FusionNet ... -
Optimal image compression via block-based adaptive colour reduction with minimal contour effect
Anbarjafari, Gholamreza; Luesi, Iiris; Bolotnikova, Anastasia; Daneshmand, Morteza; Ozcinar, Cagri (SPRINGER, 2018-12)Current image acquisition devices require tremendous amounts of storage for saving the data returned. This paper overcomes the latter drawback through proposing a colour reduction technique which first subdivides the image ... -
