This paper proposes an intelligent room that is free of operator's position based on gesture recognition technologies. Intention and position of an operator are recognized by detecting hand waving, and pan-tilt cameras are zoomed and focused on the operator. The hand region is extracted using color information, and direction or number of fingers and motion(More)
An in vitro patient-specific vascular model, for simulating endovascular intervention is presented. Proposed vascular model reproduces the 3-dimensional vessel lumen structure using CT/MRI information with 13 mum resolution, and it also reproduce the physical characteristics of arterial tissue (elastic modulus and friction coefficient). Furthermore, in this(More)
Background data during the gestation period were obtained from 128 Wistar Hannover GALAS rats and 26 Crl:CD(SD) pregnant rats in the control groups of our previous toxicity studies. The body weights of dams in the Wistar Hannover GALAS rats were significantly lower throughout the gestation period than those in the Crl:CD(SD) rats. In contrast, the(More)
This paper proposes a method of detecting waving hands from images as a method for man-machine interface. FFT is applied to time series of intensity images. The images are converted to low-resolution ones, and FFT is applied to each pixel of the low-resolution images. The proposed method is robust to lighting condition and individual difference of skin(More)
In vitro patient-tailored anatomical model of human cerebral artery, for presurgical simulation and medical training of intravascular neurosurgery, is presented. Lumens of vasculature are hollowly and precisely reproduced within a transparent elastic silicone structure, based on CT (computed tomography) or MRI (magnetic resonance imaging) angiography.(More)
