    • Convolutional neural networks for pose recognition in binary omni-directional images 

      Georgakopoulos S.V., Kottari K., Delibasis K., Plagianakos V.P., Maglogiannis I. (2016)
      In this work, we present a methodology for pose classification of silhouettes using convolutional neural networks. The training set consists exclusively from the synthetic images that are generated from three-dimensional ...

    • Enhanced CNN-Based gaze estimation on wireless capsule endoscopy images 

      Gatoula P., Dimas G., Iakovidis D.K., Koulaouzidis A. (2021)
      Wireless capsule endoscopy (WCE) is a modality used for the non-invasive examination of the gastrointestinal (GI) tract. Physicians diagnose pathologies in images derived from Capsule Endoscopy (CE) using specific gaze ...

    • H-V shadow detection based on electromagnetism-like optimization 

      Koutsiou D.-C.C., Savelonas M., Iakovidis D.K. (2021)
      Shadow detection is useful in a variety of image analysis applications, as it can improve scene understanding. Most of the recent shadow detection approaches use near-infrared (NIR) cameras and deep learning to provide ...

    • Improved Face Detector on Fisheye Images via Spherical-Domain Attention 

      Miao J., Liu Y., Liu J., Argyriou A., Xu Z., Han Y. (2021)
      As one type of omnidirectional projection, fisheye images have been widely used in automatic driving and visual surveillance. However, they cannot be processed well by the traditional algorithms designed for the planar ...

    • Improving the performance of convolutional neural network for skin image classification using the response of image analysis filters 

      Georgakopoulos S.V., Kottari K., Delibasis K., Plagianakos V.P., Maglogiannis I. (2019)
      In this work, we focus in the analysis of dermoscopy images using convolutional neural networks (CNNs). More specifically, we investigate the value of augmenting CNN inputs with the response of mid-level computer vision ...

    • Information content in nuclear medicine imaging 

      Michail C.M., Agavanakis K.N., Karpetas G.E., Kalyvas N.I., Valais I.G., Kandarakis I.S., Panayiotakis G.S., Fountos G.P. (2019)
      The aim of the present study was to investigate the information content of positron emission tomography (PET) images. We used the GATE Monte Carlo package (GEANT4 application for tomographic emission) and reconstructed ...

    • Investigating cross-dataset abnormality detection in endoscopy with a weakly-supervised multiscale convolutional neural network 

      Diamantis D., Iakovidis D.K., Koulaouzidis A. (2018)
      The detection of abnormalities in endoscopic video frames can contribute in the early and more accurate detection of pathologic conditions. In this paper we present a novel Convolutional Neural Network (CNN) architecture ...

    • Latent twitter image information for social analytics 

      Razis G., Theofilou G., Anagnostopoulos I. (2021)
      The appearance of images in social messages is continuously increasing, along with user engagement with that type of content. Analysis of social images can provide valuable latent information, often not present in the ...

    • An open web services - Based framework for data mining of biomedical image data 

      Doukas, C.; Maglogiannis, I.; Chatziioannou, A. (2009)
      Mining of biomedical image data is a complex procedure that requires several processing phases, such as data acquisition, preprocessing (e.g., image enhancement, color processing), feature extraction and classification. ...
