Wize Mirror - a smart, multisensory cardio-metabolic risk monitoring system
In the recent years personal health monitoring systems have been gaining popularity, both as a result of the pull from the general population, keen to improve well-being and early detection of possibly serious health conditions and the push from the industry eager to translate the current significant progress in computer vision and machine learning into commercial products. One of such systems is the Wize Mirror, built as a result of the FP7 funded SEMEOTICONS (SEMEiotic Oriented Technology for Individuals CardiOmetabolic risk self-assessmeNt and Self-monitoring) project. The project aims to translate the semeiotic code of the human face into computational descriptors and measures, automatically extracted from videos, multispectral images, and 3D scans of the face. The multisensory platform, being developed as the result of that project, in the form of a smart mirror, looks for signs related to cardio-metabolic risks. The goal is to enable users to self-monitor their well-being status over time and improve their life-style via tailored user guidance. This paper is focused on the description of the part of that system, utilising computer vision and machine learning techniques to perform 3D morphological analysis of the face and recognition of psycho-somatic status both linked with cardio-metabolic risks. The paper describes the concepts, methods and the developed implementations as well as reports on the results obtained on both real and synthetic datasets
Mirror mirror on the wall... an unobtrusive intelligent multisensory mirror for well-being status self-assessment and visualization
A person’s well-being status is reflected by their face through a combination of facial expressions and physical signs. The SEMEOTICONS project translates the semeiotic code of the human face into measurements and computational descriptors that are automatically extracted from images, videos and 3D scans of the face. SEMEOTICONS developed a multisensory platform in the form of a smart mirror to identify signs related to cardio-metabolic risk. The aim was to enable users to self-monitor their well-being status over time and guide them to improve their lifestyle. Significant scientific and technological challenges have been addressed to build the multisensory mirror, from touchless data acquisition, to real-time processing and integration of multimodal data
Human herpesvirus-8 seropositivity and clinical correlations in HIV-1-positive and highly exposed, persistently HIV-seronegative individuals in Greece
The prevalence of anti-human herpesvirus 8 (HHV- 8) antibodies was
retrospectively assessed in a cohort of 248 consecutive HIV-1-positive
patients followed up in an academic unit in Greece during a 14-year
period and in 46 highly exposed, persistently HIV-seronegative (HEPS)
individuals. The impact of the initial anti-HHV-8 status on tumorgenesis
and mortality was studied. The first available serum sample from the
department’s pool was tested. Demographics and data regarding history of
sexually transmitted diseases, Hepatitis B surface antigen (HbsAg) and
hepatitis C (HCV) status were collected. Patients who developed either
HHV-8-related or non-HHV-8-related neoplasms during long-term follow-up
were also identified. Forty-eight percent of the HIV-1-positive patients
and 56% of the HEPS subjects were found anti-HHV-8-positive. No
difference was observed regarding the development of HHV-8-related or
non-HHV-8-related neoplasia and mortality on grounds of initial
anti-HHV- 8 status. Mortality was positively associated with the
presence of HBsAg. HCV infection showed a trend to be more common in
anti-HHV-8-positive patients. In summary, the seroprevalence of HHV-8
among HIV-1- positive patients is higher than the one reported in the
Western world. The initial anti-HHV-8 status is not a prognostic factor
in HIV-1- positive individuals. The high seroprevalence in HEPS
individuals possibly reflects their risk- prone lifestyle.
HbsAg-positive status is a long- term negative prognostic factor in HIV
infection
