Abstract: PURPOSE: An automatic face recognizing device based on a multi face feature information fusion is provided to recognize a face through the multiple face feature fusion by obtaining multiple face images through the division of an input video. CONSTITUTION: A shot detector(110) classifies video frame sequences of an input video into a plurality of video shots. A face image detector(120) extracts face images from the plurality of video shots. A face image collector(130) collects multiple face images included in the same people among the detected face images. A facial feature extractor(140) extracts the multiple facial feature information from corresponding face images. A face recognizer(150) recognizes a face through the extracted face feature information.

Abstract: PURPOSE: A passive safe system of a nuclear power plant integrated into the outside of a containment building is provided to reduce the pressure and temperature of the inside of the containment building and preserve the furnace of a melting core by installing a heat exchanger and a pipe, which are associated with one integrated passive safe tank, at the outside of the containment building of a pressurizing light water reactor type nuclear power plant. CONSTITUTION: An integrated passive safe tank(160) is installed at both sides of a containment building in which a pressurizing vessel and a steam generator(120) are installed. A passive core cooling system part injects the coolant inside the integrated passive safe tank into the pressurizing vessel if a coolant loss accident occurs. A passive auxiliary feed water system part comprises a passive feed water cooling heat exchanger(250) installed in the integrated passive safe tank. A passive containment building cooling system part reduces pressure and temperature inside the containment building with the coolant supplied from the integrated passive safe tank. The passive containment building cooling system part comprises a passive containment building cooling heat exchanger(260) installed in the containment building. A passive melting core furnace preserve system part supplies the coolant inside the integrated passive safe tank to a cavity installed at the lower part of the pressure vessel and cools the pressure vessel.
