Abstract: A stereo vision system and an image processing method thereof are provided to efficiently remove image noise by using a motion vector of an image, thereby obtaining exact distance information on a stereo image. An inputted stereo image is pre-processed. Low-resolution distance information using an image compression module about the pre-processed stereo image is obtained(616). High-resolution distance information is obtained through a stereo matching module(622). A motion vector is extracted by utilizing the image compression module. Image noise is eliminated by using the high-resolution distance information and the extracted motion vector(624). The motion vector is extracted through a motion estimation technique by alternately inputting the stereo image.

Abstract: PURPOSE: A controller of ring switch in a digital transmitting system is provided to freely set a path by performing the ring switch with one control command of ring switch transmitted from an outer processor for controlling the ring switch of the SDH(synchronous digital hierarchy) digital transmitting system. CONSTITUTION: If there is a difficulty in two east optical fibers(for transmission and receiving), a signal(ABCD)(an AB is a signal of a working band and a CD is a signal of a protection band) inputted to an optical fiber(620) performs a branch and a signal A is outputted to an optical fiber(670). A signal EBCD is formed by combining an inputting tributary signal E. The signal EBCD is outputted to east in a normal operation, however a ring switch is performed because the east line has a defect. The ring switch switches the signal EBCD to a signal CDEB(switches a working band and the protection band). The east input signal is branched, combined and passed in the normal operation, however an output is performed to west after forming a signal CFEB by branching a signal D to an output tributary signal and by combining an inputting tributary signal F in the CDEB using the CDEB as an outputting signal of the ring switch instead of the east input signal.
