Action Recognition Using Single-Pixel Time-of-Flight Detection
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 ... -
Audio-Visual Emotion Recognition in Video Clips
Anbarjafari, Gholamreza; Noroozi, Fatemeh; Marjanovic, Marina; Njegus, Angelina; Escalera, Sergio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019-01)This paper presents a multimodal emotion recognition system, which is based on the analysis of audio and visual cues. From the audio channel, Mel-Frequency Cepstral Coefficients, Filter Bank Energies and prosodic features ... -
Automatic garment retexturing based on infrared information
Anbarjafari, Gholamreza; Avots, Egils; Daneshmand, Morteza; Traumann, Andres; Escalera, Sergio (PERGAMON-ELSEVIER SCIENCE LTD, 2016-10)This paper introduces a new automatic technique for garment retexturing using a single static image along with the depth and infrared information obtained using the Microsoft Kinect II as the RGB-D acquisition device. ... -
Automatic Recognition of Facial Displays of Unfelt Emotions
Kulkarni, Kaustubh; Corneanu, Ciprian Adrian; Ofodile, Ikechukwu; Escalera, Sergio; Baro, Xavier; Allik, Juri; Anbarjafari, Gholamreza (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, APR-JUN 20)Humans modify their facial expressions in order to communicate their internal states and sometimes to mislead observers regarding their true emotional states. Evidence in experimental psychology shows that discriminative ... -
ChaLearn Looking at People: IsoGD and ConGD Large-Scale RGB-D Gesture Recognition
Wan, Jun; Lin, Chi; Wen, Longyin; Li, Yunan; Miao, Qiguang; Escalera, Sergio; Anbarjafari, Gholamreza; Guyon, Isabelle; Guo, Guodong; Li, Stan Z. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, MAY 2022)The ChaLearn large-scale gesture recognition challenge has run twice in two workshops in conjunction with the International Conference on Pattern Recognition (ICPR) 2016 and International Conference on Computer Vision ... -
Dominant and Complementary Emotion Recognition From Still Images of Faces
Anbarjafari, Gholamreza; Guo, Jianzhu; Lei, Zhen; Wan, Jun; Avots, Egils; Hajarolasvadi, Noushin; Knyazev, Boris; Kuharenko, Artem; Silveira Jacques Junior, Julio C.; Baro, Xavier; Demirel, Hasan; Escalera, Sergio; Allik, Jueri (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018)Emotion recognition has a key role in affective computing. Recently, fine-grained emotion analysis, such as compound facial expression of emotions, has attracted high interest of researchers working on affective computing. ... -
From 2D to 3D geodesic-based garment matching
Anbarjafari, Gholamreza; Avots, Egils; Madadi, Meysam; Escalera, Sergio; Gonzalez, Jordi; Baro, Xavier; Pallin, Paul (Springer, 2019-09)A new approach for 2D to 3D garment retexturing is proposed based on Gaussian mixture models and thin plate splines (TPS). An automatically segmented garment of an individual is matched to a new source garment and rendered, ... -
From apparent to real age: Gender, age, ethnic, makeup, and expression bias analysis in real age estimation
Clapes, Albert; Anbarjafari, Gholamreza; Bilici, Ozan; Temirova, Dariia; Avots, Egils; Escalera, Sergio (IEEE Computer Society, 2018-12-13)Real age estimation in still images of faces is an active area of research in the computer vision community. However, very few works attempted to analyse the apparent age as perceived by observers. Apparent age estimation ... -
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 ... -
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 ... -
