Intelligent Design Support System for Japanese Kimono
A yukata is a type of traditional Japanese clothing. The designers have difficulty in drawing its cutting pattern with texture alignment. In this paper, we describe a CAD system for the yukata. First, we developed image processing algorithms for achieving the texture alignment. Second, we developed a measurement system for the wearer's body shape. Third, a three-dimensional garment simulation was achieved. By using this system, designers easily tailor the yukata regardless of their skill </p
Multi Agent Micromanipulation System
In the area of biotechnology, a micromanipulation is widely used for such purposes as operating on genes and transferring biological materials into cells. For the some experiments, such as biochemical experiment, a large number of cells have to be manipulated in a short time. We have developed an automatic micromanipulation system under the stereoscopic microscope. Micromanipulation system carries out various processes, such as detection of the target, the detection of the needle head, and motor control. By sharing these processes with several computers, the micromanipulation can be performed at high speed. As a result, computer cooperation becomes very important. In this paper, we propose a multi agent micromanipulation system. At first, we developed a multi agent system, which performs image processing, motor control, and management of the micromanipulation processes. Secondarily, we proposed to operate computers cooperative. We use a computer as a single agent. And several computers are connected to a local area network. The multi agent micromanipulation system performed the micromanipulation at a realistic rate through cooperation of multi agents.</p
Study of micromanipulation using stereoscopic microscope
In this paper, we describe a visual feedback system using a stereoscopic microscope that controls a micromanipulator so that a needle may pierce a target as much length as desired. At first, for achieving the manipulation at a realistic rate, we proposed a strategy of moving the needle head. Secondarily, we developed an algorithm for prediction of the tip position of the needle head within the target. Before the needle pierces the target, the shape of the needle head is preserved as a reference pattern. After the needle piercing the target, the shape of the needle head within the target is predicted using the reference pattern and the tip position of the needle head can be detected. Experimental results indicate that the proposed system may be useful in micromanipulation such as microinjection to seeds </p
Micromanipulation using Stereoscopic Microscope
this paper, we developed a visual feedback
system that controls a micromanipulator so that a needle
head may reach a target. The system consists of a
stereoscopic microscope, a micromanipulator, two CCD
cameras and a personal computer, The positions of the
target and the needle head under stereoscopic microscope
are measured three dimensionally by using two
CCD cameras which are set to eyepieces of the microscope.
In order that the micromanipulation can be carried
out at a realistic rate, it is necessary that the image
processing is employed be fast. The image processing
time for detecting the target and the needle head is
greatly reduced by using image data compression.</p
