Cardiovascular diseases are the leading cause of mortality worldwide and impose a tremendous burden on socio-economic costs. At present, prevention strategies based on personalized lifestyle interventions are considered the best way to contain the epidemics of these diseases. In this view, availability of innovative technological systems able to assist people in self-monitoring and self-coaching is...
Presentation attack on the face recognition systems is well studied in the biometrics community resulting in various techniques for detecting the attacks. A low-cost presentation attack (e.g. print attacks) on face recognition systems has been demonstrated for systems operating in visible, multispectral (visible and near infrared spectrum) and extended multispectral (more than two spectral bands spanning...
The study of emotions in human-computer interaction has increased in the recent years. With successful classification of emotions, we could get instant feedback from users, gain better understanding of the human behavior while using the information technologies and thus make the systems and user interfaces more emphatic and intelligent. In our work, we focused on two approaches, namely emotions detection...
In this paper, a human speaker tracking method on audio and video data is presented. It is applied to conversation tracking with a robot. Audiovisual data fusion is performed in a two-steps process. Detection is performed independently on each modality: face detection based on skin color on video data and sound source localization based on the time delay of arrival on audio data. The results of those...
What if you could discover your health status by looking at yourself in the mirror? Since November 2013, the EU FP7 Project SEMEOTICONS is working to make this possible. The Project is building a multi-sensory device, having the form of a conventional mirror, able to read the semeiotic code of the face and detect possible evidence of the onset of cardio-metabolic diseases. The device, called Wize...
Persons suffering from intractable disease like ALS (Amyotrophic Lateral Sclerosis) and spinal cord injured present symptoms of muscular deteriorations. These patients are often obliged to use artificial respirators once the breathing action becomes impossible. It is important to understand that using the artificial respirator means that uttering voice becomes impossible. For human being talking and...
This paper presents an electronic travel aid for blind people to navigate safely and quickly, an obstacle detection system using ultrasonic sensors and USB camera based visual navigation has been considered. The proposed system detects the obstacles up to 300 cm via sonar and sends feedback (beep sound) to inform the person about its location. In addition to this, an USB webcam is connected with eBox...
The spatial connection system called the Virtual Window System has proposed as a communication system between remote places. Virtual Window System uses a vista image display called the virtual window. The virtual window assumes a metaphor of window between two neighbored rooms. The displayed scene image of VW is changed by shifting view position and view height. In this article, a new position sensing...
In quantitative dermatology, high resolution sensors provide images that capture fine scale features like pores, birthmarks, and moles. Breathing and minute movements result in misregistration of micro level features. Many computer vision methods for dermatology such as change detection, appearance capture, and multi sensor fusion require high accuracy point-wise registration of micro level features...
