Background: Tendencies to increase the mean size of dental images and the number of images acquired daily makes necessary their compression for efficient storage and transferring via communication lines in telemedicine and other applications. To be a proper solution, lossy compression techniques have to provide a visually lossless option (mode) whe...

Here we consider lossy compression of grayscale dental images. To preserve valuable diagnostic information, we propose to carry out visually lossless compression. For this purpose, it is proposed to apply better portable graphics (BPG) coder for which quality and compression ratio is controlled by the quality parameter Q. To provide invisibility of...

Automatic screening of the population for congestive heart failure (CHF) is a matter of pressing concern due to the severity of the health consequences resulting in disability and death of people. On the one hand, portable devices working with ECG signals become convenient tools for the lay user due to the simplicity. On the other hand, analyzing t...

Remote sensing and medical imaging are very important in human’s life. The former deals with many applications from weather monitoring to military purposes and is performed by sensors mounted onboard of satellite and aerospace carriers. Medical imaging assists in disease detection and diagnostics. Images acquired by synthetic aperture radar or ultr...

With the sharp rise in the incidence of diabetes worldwide, the screening diagnosis of this disease is one of the most pressing public health concerns. A model that allows differentiating patients with and without diabetes mellitus is proposed in this study. The target group consisted of diabetics of different ages and sex, and the control group in...

In this paper, the authors consider how to label and save a large number of images that should be predicted in a single file. The technique of automatic labeling the data set with the finite element model for training of artificial neural network in tomography are proposed. A simple transparent example of thirty-two images to be predicted in a sing...

It is known that every day 2,500 children under the age of 18 try their first cigarette, and more than 400 of them become new, regular smokers, and half of them will die from this addiction in the future. Aim: The aim of the study is to determine changes in the indices of dental status in adolescents with tobacco smoking. Materials and methods:...

The electrocardiogram (ECG) of the first lead, obtained using portable signal collection tools is noise sensitive. One of the most common and poorly filterable types of noise is muscle artefact. As a result of the simulation, a criterion was found that identifies situations in which the use of kernel-based ECG smoothing after the filtering stage is...

Noninvasive medical personal systems, which use cloud services for data processing, become a trend in the era of rapid development of the Internet of Things (IoT). Herewith, the use of ECG of the first standard lead (limb lead I), as the primary signal being detected, is becoming more widespread. It's due to the convenient and user-friendly procedu...

Technique of automatic labeling the data set with finite element model for training of artificial neural network in tomography are proposed. Simple transparent example of sixteen images for predict in a single HDF5 file traini...

Improvement of algorithms for detecting the signs of pathologies, when using only the time HRV, is a very actual issue. Besides, it is desirable to shorten the time of measurement and reduce the number of leads to one. In this case, such a system can be used not only by a medical professional, but also by an untrained user, and also be connected to...

Objective: To find correlation between the total antioxidant and periodontal status in the saliva of periodontally compromised and not compromised patients, respectively, with atopy, and healthy controls (HC) to assess diagnostic utility of malondialdehyde (MDA), glutathione and superoxide dismutase. Methods: The study was conducted on 141 subjects...

Background and aims: Prevalence of atopic diseases is progressively increasing in children with unclear clinical picture in oral cavity. This study aimed to find correlation between the total antioxidant and periodontal status in the saliva of periodontally compromised with atopy. Materials and methods: The groups consisted of patients of atopic...

Conference Paper
An Information and Communication Technology for caries intensity evaluation for children with allergic diseases is proposed. The method is based on a Pareto chart and a digital convergence prism. The Pareto chart is one of the seven basic tools of quality control. The method has been tested during the clinical examination of 110 children of individ...
