The attention function has been classified into (i) sustained attention, (ii) selective attention, (iii) controlled attention, (iv) distributed attention, and (v) capacity for attention. Ordinarily, in order to evaluate the function of attention, the digital cancellation test (D-CAT) or trail making test (TMT) are employed. However, these evaluations are in the form of paper tests, and cannot effectively...
Dermoscopy is the in vivo technique of skin surface microscopy which is frequently used in visual examination of the skin. With the rise in the usage of smartphones, many smartphone attachments have been developed that enable dermoscopy on a phone but these attachments are very expensive and are available only for high-end phones. We have developed a novel 3D printed clip-on that can convert any smartphone...
This paper presents a study of human behavior related to different marketing stimuli based on pupillometry data. The consumer's gaze points on products of interest are acquired with a remote eye tracker and the obtained heatmaps and timestamps are used for further analysis. An application for recording user's visual attention on web pages and advertising slides is implemented. A sensor for electrodermal...
Facial wrinkle is one of the most prominent biological changes that accompanying the natural aging process. However, there are some external factors contributing to premature wrinkles development, such as sun exposure and smoking. Clinical studies have shown that heavy smoking causes premature wrinkles development. However, there is no computerised system that can automatically assess the facial wrinkles...
Radiotherapy aims at irradiating tumor tissue, while sparing normal tissue as much as possible and it is a suitable treatment option for prostate cancer. A crucial aspect of the radiotherapy workflow is patient positioning. It has been shown that frequent imaging during the course of the treatment (image guided radiotherapy) can improve this positioning accuracy. Despite the many advantages of ultrasound...
Physical interactions between human and machine are essential in facilitating effective physical therapy training programs. Nowadays, physical training largely involves robotic assistive devices or wearable haptics. In this study, we propose a lightweight wearable sensory augmentation device using skin stretch feedback to provide individuals with additional sensory cues during balance training. The...
Results of the analysis of the review of references on morphological structure of acupuncture points are presented. It is noted that in the biologically active points (BAP) are revealed a congestion of the corpulent cages distributed on depth of an integument, promoting distribution of communication between a point and internal body that living cells can accumulate energy and radiate it in the visible...
Dermoscopy is a non-invasive in vivo technique to help visualize morphological structures on the surface and subsurface of the skin, non-visible with the naked eye. It is tipically used to improve the diagnostic accuracy of pigmented skin lesions and skin tumors, but in recent years its use has been extended to other dermatological conditions. The use of polarized light in dermoscopy allows a better...
Chickenpox is caused by the varicella-zoster virus (a member of the herpes virus family), which can be spread through the air or by direct contact with an infected person. It produces an itchy, blistery rash that typically lasts about a week and is sometimes accompanied by a fever or other symptoms but primarily manifested by numerous blisters. A single attack of chickenpox almost always brings lifelong...
Dermoscopy image is usually used in early diagnosis of malignant melanoma. The diagnosis accuracy by visual inspection is highly relied on the dermatologist's clinical experience. Due to the inaccuracy, subjectivity, and poor reproducibility of human judgement, an automatic recognition algorithm of dermoscopy image is highly desired. In this work, we present a hybrid classification framework for dermoscopy...
While the abundance of visual content available on the Internet, and the easy access to such content by all users allows us to find relevant content quickly, it also poses challenges. For example, if a parent wants to restrict the visual content which their child can see, this content needs to either be automatically tagged as offensive or not, or a computer vision algorithm needs to be trained to...
A review of market of the modern noninvasive devices of visualization human vascular bed was conducted. The collaborative mechanism of radiation in visible range and near IR range with observation object, which lead to weakening of contrast, was offered. The method rise of contrast sensitivity at the observing the low in contrast objects in biological tissues and TV system, which implemented it, was...
In this study, we investigate what a practically useful approach is in order to achieve robust skin disease diagnosis. A direct approach is to target the ground truth diagnosis labels, while an alternative approach instead focuses on determining skin lesion characteristics that are more visually consistent and discernible. We argue that, for computer aided skin disease diagnosis, it is both more realistic...
Skin appearance is almost universally the object of gender-related expectations and stereotypes. This not with standing, remarkably little work has been done on establishing quantitatively whether skin texture can be used for gender discrimination. We present a detailed analysis of the skin texture of 43 subjects based on two complementary imaging modalities afforded by a visible-light dermoscope...
Psoriasis is an inflammatory skin disease that spreads worldwide and damages the skin or other body tissues. However, normal visual clinical examination is not always sufficient to determine the feature of the lesions. In this research, we focus on a background removal method that support to enhance the ratio contrast of scalingagainst erythema to skin background in polarized psoriasis images. Those...
Some actual problems of electronic instrument engineering in the field of reflexotherapy were revealed following the works of researchers of Interuniversity Laboratory for Medical Electronics in NSTU. It is shown that the main problems in the considered field are: 1) realization, clinical testing and inclusion into medical practice of the multifunctional device for reflexotherapy with spatial and...
Many skin detection approaches have been proposed in the image analysis literature. Some are simple and static; the others are dynamic and rely on complex machine learning algorithms and training data. Generally the simple approaches are preferred. We hypothesize that the developers' choice for the simple approaches are due to the reasonable quality of results and ease of implementation, since the...
We address self-perception and object discovery by integrating multimodal tactile, proprioceptive and visual cues. Considering sensory signals as the only way to obtain relevant information about the environment, we enable a humanoid robot to infer potential usable objects relating visual self-detection with tactile cues. Hierarchical Bayesian models are combined with signal processing and protoobject...
The algorithm is applied to the field of hand gesture recognition by Referencing the Bag of Feature (BoF) algorithm in the field of target recognition and image retrieval. First of all, this paper uses the HSV skin color adaptive method to segment the gesture's information from body and uses SURF algorithm to extract the feature of the image. After feature extraction, it uses BoF algorithm to generate...
