Robust non-blind color video watermarking using QR decomposition and entropy analysis
(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 ...
Efficiency of chosen speech descriptors in relation to emotion recognition
This research paper presents parametrization of emotional speech using a pool of common features utilized in emotion recognition such as fundamental frequency, formants, energy, MFCC, PLP, and LPC coefficients. The pool ...
Dominant and Complementary Emotion Recognition From Still Images of Faces
(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 apparent to real age: Gender, age, ethnic, makeup, and expression bias analysis in real age estimation
(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 ...
Interpenetrated triple polymeric layer as electrochemomechanical actuator: Solvent influence and diffusion coefficient of counterions
(PERGAMON-ELSEVIER SCIENCE LTD, 2017-03-10)
Full polymeric trilayers formed by two lateral polypyrrole-dodecylbenzoesulfate (PPyDBS) films interpenetrating a polyvinylidene fluoride (PVdF) central membrane were electrochemically characterized. Square wave voltammetric ...
Virtual Reality and Its Applications in Education: Survey
In the education process, students face problems with understanding due to the complexity, necessity of abstract thinking and concepts. More and more educational centres around the world have started to introduce powerful ...
Audio-Visual Emotion Recognition in Video Clips
(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 ...
Guest editorial: special issue on human abnormal behavioural analysis
(Springer Verlag, 2019-07-01)
Action Recognition Using Single-Pixel Time-of-Flight Detection
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 ...
Low-quality fingerprint classification using deep neural network
(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. ...
