This paper describes the development of a new tactile sensing device that imitates the distribution of nerves in human skin using two types of sensing device, an absolute pressure sensor and a force sensing register. The absolute pressure sensor detects both pressure and temperature, while the force sensing register detects pain. A PSoC microcontroller is used to combine these sensing devices. To...
The increasing number of skin-related diseases for the past decades has increased the awareness in our society about the factors that might contribute to it. In this paper, the effects of daily physical exposure, lifestyle and type of food consumed on human skin are discussed. One hundred UiTM staffs were chosen based on their different characteristics to undergo a skin test and answer questionnaires...
The problem in accurate and fast face detection and tracking in video images with complex background is studied in this paper. In order to meet both of speed and accuracy, a face detection method integrating the skin color segmentation and Split up Sparse Network of Winnows (SNoW) is presented. This kind of method can not only utilize the advantage of skin color segmentation to remove the interference...
Nowadays there exists a large variety of aspect ratios used for both image rendering (e.g. print media, TV, cinema screens etc.) and image acquisition devices (e.g. still and video cameras, scanners etc.). In order to maintain the image's original aspect ratio when adjusting for a different media, some level of cropping may be required, but the automatic zoom and crop method may not produce satisfactory...
Aiming at the human face detection in color images under complex background, a face detection method based on the combination of skin color model in YCgCr and AdaBoost algorithm is proposed in this article. Firstly, it uses skin color model in YCgCr color space to detect candidate face region in the tested image, and then further verifies the face region by the Adaboost algorithm with the added new...
Current work focuses on user modeling in terms of affective analysis that could in turn be used in intelligent personalized interfaces and systems, dynamic profiling and context-aware multimedia applications. The analysis performed within this work comprises of statistical processing and classification of automatically extracted gestural and head pose expressivity features. Computational formulation...
Microbes found on the skin are usually regarded as pathogens, potential pathogens or innocuous symbiotic organisms. Advances in microbiology and immunology are revising our understanding of the molecular mechanisms of microbial virulence and the specific events involved in the host-microbe interaction. A microbial community similarity function of skin sites was defined to analysis the topographical...
Inspired by human's tactile sensing in daily lives, we present an approach using the tactile sensing plus force-torque information as the feedback to control the robotic arm interacting with our soft human skin in this paper. Three main types of contact between the end-effector of robotic arm and human skin are introduced and the contact model is built up. Hybrid impedance control method is applied...
Knowing biomechanical properties of human skin is important for clinical decision making as well as clinical intervention. Measuring these properties in vivo is essential. However, existing devices don't respect the fact, that human skin is an anisotropic material. Nowadays devices investigate mostly the human skin anisotropy by uniaxial testing. This leads leads to distorted information. In this...
It is possible that protein carbonylation in the stratum corneum might be used as an index of skin photo-stress. In order to evaluate the relationship between the protein carbonyl/total protein ratio (carbonylation ratio) and skin photo-stress, the authors established a methodology by which protein carbonyl can be quantitatively analyzed using an optical technique based on surface plasmon resonance...
This paper presents an automatic people counting system based on face detection, where the number of people passing through a gate or door is counted by setting a video camera. The basic idea is to first use the frame difference to detect the rough edges of moving people and then use the chromatic feature to locate the people face. Based on NCC (Normalized Color Coordinates) color space, the initial...
In our previous work, we proposed a process optimized hollow silicon (Si) microneedle structure on a silicon chip, which had the highest aspect ratio (AR) reported so far. The 150 micrometer (μm) tall optimized microneedle structure with an AR of about 30:1 was fabricated by reactive ion etch or RIE process on a p-type 500 μm thick Si substrate for drug delivery applications. In this paper we have...
Face detection is the first step in automated face recognition and the important cue to detect the human face is skin color. This proposed paper consists of two steps, the first step is to detect the more skinned region by the fusion of RGB, YCbCr skin color region and CIEL* a* b skin labeled image using HillClimbing segmentation with K-Means clustering. This step helps to simplify and improves the...
The paper aims at exploring advantages and drawbacks of using high-frequency inductive links to transmit power wirelessly to implanted biosensors. A system with an external transmitting coil located into a skin patch and a receiving coil embedded into a fully implanted biosensor is simulated. The effects of the geometry of the coils on the optimal working frequencies and on the power gain have been...
Mammalian adipose tissue derived stem cells have a tremendous potential in regenerative medicine for tissue engineering and somatic nuclear transfer (SNT). The isolation methods of human and bovine adipose tissue derived stem cells are compared in this paper to determine the feasibility and optimum method of isolation. The optimum isolation method will reduce the processing time, efforts and money...
We propose a skin-type tactile sensor with standing piezoresistive cantilever to detect micro size texture of object. By forming micro ridges to the sensor surface as a finger print, the sensitivity of the tactile sensor increased for micro texture scanning. This characteristic enabled the detection of 500nm high 300μm wide bumps arranged with 50μm pitch on a flat surface. This...
Dermoscopy is one of the major imaging modalities used in the diagnosis of skin lesions such as melanoma and other pigmented lesions. Due to the difficulty and subjectivity of human interpretation, computerized analysis of dermoscopy images has become an important research area. One of the most important steps in dermoscopy image analysis is the automated detection of lesion borders. In this paper...
Human face tracker is one of important research areas that is continuously developing.

This paper presents a real-time human face tracker development using facial feature...
Electroporation is an elegant technique used for proliferation control in Cancer cells. This budding mode of therapy called electrochemotherapy uses electrical pulses and chemodrugs to trigger cell death in cancerous cells. The efficacy of this technique depends on a variety of factors including electric field intensity, pulse duration and the number of pulses. In this study, Human cervical (ME180),...
Breast cancer is the one of the most leading diseases and cause of death in the world. 21% of females diagnosed with breast cancer in 2009 did not survive. Hence, cancer therapy requires a new and novel approach to treat them. Over the last two decades, electroporation, which is the process by which external electrical pulses are applied to facilitate the transport of drugs into cells, is gaining...
