In t h e case of a marine casualty occurs, the detection of the rescue target such as life rafts depends on the visual search by man as yet. However, human eyes sometimes lose its sight owing to a long flight and wide views. In order to carry out the prompt rescue of human life, development of t h e searching system in place of t h e human eyes is surely required. This paper deals with a new search method for detection of the rescue target using image processing techniques.
To detect t h e small target in t h e wide views over t h e sea, we have proposed a new method including t h e image processing techniques based on t h e color information and t h e c o m p o s i t e image sensor which increases about t h emeasurement accuracy and the image processing speed at actual field. A t t h e first step of t h e study, we attempt ta extract the image data o f t h e rescue target with t h e orange color i n an experimental sea.
A Stereoscopic microscope is widely used in a micre between the object and the needle is derived. The mimanipulation such as to operate genes and to inspect integration circuits. As in these tasks the micromanipulation is handled and makes too heavy burden to operators, it is desirable to perform cromanipulator is controlled to make this error signal to zero. The objects are colored bea.ds with 2mm diameter instead of the cells. The needle 0.6" in diameter 20" the nlicrornanipulation automatically. In this paper, we propose a. . ~. visual feedback system for micromanipulation with stereoscopic microscope. This system takes less time to control the manipulator by reducing searching area to detect an object. in length is attached to the micromanipulator. The detection of the corresponding point in the left and right images, measuring of the focal distance of the camera and the distance between the cameras become necessary in the stereo-vision method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
