MicroRNAs (miRNAs) have been shown to have important roles in various cellular processes, such as metabolism, proliferation, apoptosis, differentiation, and development. Recent studies have shown that the expression of miRNAs is deregulated in human cancers in which miRNAs can exert their effect as oncogenes or tumor suppressors. The widespread and comprehensive use of miRNA microarrays has enabled...
This paper proposes a new algorithm for deciding the starting lens focus direction and speed in aid of contrast autofocus using only one initial image with blur detection. Simulation results show that the fundamental idea could support contrast auto-focus in reducing operation time by deciding appropriate starting direction in some certain circumstances.
Osteoporosis is characterized by an abnormal loss of bone mineral content, which leads to a tendency to non-traumatic bone fractures or to structural deformations of bone. Thus, bone density has been considered as a most reliable parameter to assess osteoporotic fracture risk. In past decades, by the way, bone texture measures have been studied to estimate other aspect of bone quality. Some studies...
In this paper we propose CINETOON, a semi-automated system which can generate black/white comic books from a sequence of video streams obtained from cinemas. CINETOON provides an intuitive interface to render comics. Our system consists of four major components : Key Frame Extractor, Image-based Comic Cut Converter, Background Effect Stylizer and Comic Elements Renderer. First, to capture the frame...
Due to the popular use of digital cameras and the growing capacity of storage, managing a large collection of digital photos is a burdensome job for the average customers. One distinct feature of current digital photos is that image contents are embedded with metadata EXIF, which varies among digital camera manufactures. Since these metadata have abundant information about the photographing environment,...
Efforts have been made to measure the distance traveled by humans in motion, in ways that are compact and accurate, for a long time. There are several ways to measure the distance moved by walking or running in daily life, some of which already use commercial products, but those methods are inaccurate. In this study, a new method is provided using ultrasonic sensors, and this is the fundamental study...
Various statistical parameters have been tried for the computer-aided diagnosis of the liver fibrosis. The region of interest (ROI) for the liver and spleen parenchymas have been chosen, and the hepatolienal textural contrast for each ultrasound (US) image has been examined. The selectively chosen textural parameters are linearly combined with the pre-determined coefficients to give the computer-aided...
Osteoporosis is characterized by an abnormal loss of bone mineral content, which leads to a tendency to non-traumatic bone fractures or to structural deformations of bone. Thus, bone density measurement has been considered as a most reliable method to assess bone fracture risk due to osteoporosis. In past decades, X-ray images have been studied in connection with the bone mineral density estimation...
The detection of abnormal lesions in the early stages of lung cancer is important to improve survival. Computer-aided detection (CAD) system can be useful for early detection of pulmonary nodules on computed tomography (CT) images for screening. Moreover, CAD system can be `second opinion' when a radiologist detects the pulmonary nodules on multi-slice CT images. We developed a computer-aided detection...

Tinnitus is defined as an unwanted auditory perception of internal origin, usually localized, and rarely heard by others. Persisting appearances of tinnitus are most commonly combined with diseases or damage in the inner ear or neuro-auditory pathway. Diffusion tensor magnetic resonance imaging (DTI) is a new imaging method with the capability of providing non-invasive information on tissue microstructure...

We investigated the B-mode ultrasound (US) images of abdomen by normalizing the gray level values of the liver with the representative gray levels (RGL's) of the liver parenchyma, renal cortex, subcutaneous fat, to quantify the fatty infiltration of the liver (FIL). The RGL's were compared with the clinical diagnosis of the FIL showing good correlation between them
