Tactile sensations experienced by humans, such as roughness and softness, require not only high-frequency (200 Hz) but also lower-frequency vibrations (< 50 Hz). However, such low frequencies are difficult to achieve with small actuators that can be integrated into mobile devices. Therefore, it is necessary to develop methods for enhancing human vibrotactile sensitivity. We focused on a phenomenon...
Human skin detection is a very popular in much application, particularly in video surveillance. Many researchers have been conducting research in this area, by producing a variety of effective methods. In this paper, research carried out by using a simple and effective. A method of human skin region detection is base on Mixture of Gaussian (MoG) background subtraction and YIQ color enhancement. The...
We present a novel lifelog system concept created to provide a human user with feedback on their conscious and unconscious emotional reactions and encourage the process of self-reflection by looking into an affective mirror. The emotion of the user is deduced from biometric data and enhanced by affective sound analysis and facial expression recognition of faces of the weares conversational partners...
This paper proposes an active air mat that improves comfortableness and easiness to wear an exoskeleton on a forearm. They are ones of important factors for the system performance evaluation in addition to physical support functions of the system. The active air mat which is installed in interface parts of the exoskeleton enables a wearer to attach and release the exoskeleton in an easy way and a...
Human skin detection in images is desirable in many practical applications, e.g., adult-content filtering. However, existing methods are mainly pixel-based and ignore that human skin is region-based. In this paper, we introduce a successful region detector, i.e., MSER, into the skin detection by regarding the skin region as the maximally stable extremal region (MSER). We extend the original MSER to...
In this paper a simple and efficient method is proposed for detecting eye positions which are used in Neuro-Linguistic Programming (NLP) as clues for the human internal representational system and mental activity. The algorithm takes as input a square crop of a face and locates the eyes using a fast and efficient color-based method. The gaze direction is then detected based on the relative position...
The paper presents an algorithm designed to face and facial features (eyes, eyebrows) detection. First, human skin regions are segmented and processed by morphological operators to detect the human face. After the face has been detected, a series of parameters that will be taken into account by the eyes detection stage are calculated. The most important parameters are face orientation and distance...
In this paper, we propose an approach that fuses information from a network of visual sensors for the analysis of human social behavior. A discriminative interaction classifier is trained based on the relative head orientation and distance between a pair of people. Specifically, we explore human interaction detection at different levels of feature fusion and decision fusion. While feature fusion mitigates...
In this paper, we propose a method of eye detection based on skin color analysis under varying illumination. The proposed method consists of several phases, including color conversion, skin color segmentation and face mask calculation, facial feature extraction and eye candidate determination, and detection of human eyes. To eliminate the effect of lighting change on the performance of eye detection,...
Diabetes mellitus is a universal disease, and insulin is essential to control patients' blood glucose level. In some clinical cases, the diabetic patients suffer from insulin allergy, and even some of them fall into allergic shock and death. In order to analyze the potential influence of insulin allergy on systematic organs, here we report a 64-year-old patient with type 2 diabetes mellitus and administrated...
Since the implementation of Tobacco Hazards Prevention Act, the prohibition against smoking in public places tends to be stricter in Taiwan. Its emphasis level can be inferred from the frequent law amendments in recent years. In order to effectively improve the prevention effect and bring down the costs of human surveillance, this paper proposes a smoking behavior detection system based on the human...
In recent years, with the implementation of Human Genome Project and the International HapMap Project as well as the high-throughput technology, Genome-Wide Association Study (GWAS) has been developing rapidly. Using this technology, researchers have found a series of related-genes or mutations associated with complex diseases. Psoriasis is a common clinical chronic inflammatory skin disease with...
Arsenic exposure from drinking water was considered to be a risk factor for skin lesions. In our research, the total arsenic in water and urine samples were analyzed by ICP-MS and AFS, respectively, Arsenic concentration in drinking water was 4.04–720μg/L, and there were 63.49% (80/126) samples above 50μg/L. Urinary total arsenic concentration was 6.51–775.73μg/gCr. Spearman rank correlation was used...
Reliable and fast hand detection is crucial for gesture-based human-computer-interface. It is natural to utilize hand-skin color to detect hands in images. However, skin-color feature is sensitive to variations in illumination, and occurrence of shadow. Therefore, color correction plays an important role for skin-color based detection algorithms. But classical Retinex method is not suitable for correcting...
Thermal infrared imaging (TIRI) employs a focal plane array (FPA) of infrared detectors, with associated optics and optoelectronics to remotely detect and topographically map thermal emittance. Thermal and optical properties of human physioanatomy are not fully understood yet confounding diagnostic interpretation of human TIRI's. Elucidation of the specific physical mechanism via which thermal emission...

The skinpatch works...
VirtualShave is a novel tool to remove hair from digital dermatoscopic images. First, individual hairs are identified using a top-hat filter followed by morphological postprocessing. Then, they are replaced through PDE-based inpainting with an estimate of the underlying occluded skin. VirtualShave's performance is comparable to that of a human operator removing hair manually, and the resulting images...
Human grasping and manipulation are facilitated by cutaneous mechanoreceptors that provide information about contact location, pressure, and events such as making and breaking contact. A challenge in designing haptic feedback devices for the wearer of a prosthetic hand is simultaneous display of multiple types of haptic information. We present the preliminary design and evaluation of an apparatus...
The aim of this study is to design of a small size implantable antenna involving Industrial, Scientific and Medical (ISM) (2.4 GHz-2.48 GHz) band. The goal of designing antenna is to obtain physiological information pertaining to person. Simulation measurements of antenna were obtained in body ambient by making the design of antenna with CST Studio Suite programme. Then, in vitro measurements were...
Automatic detection of human face features plays a significant role in expression recognition and human computer interaction. Human eyebrows shape has good specificity and stability, hence precise localization outlines a series of threads for face expression analysis.
