    • PURPOSE: A real time voice activity detecting device and a method thereof are provided to store a voice signal in a plurality of parallel buffers and simultaneously extract two feature information from the stored data. CONSTITUTION: A sound signal buffering unit(120) buffers a digital sound signal of a sound signal obtaining unit(110). A periodicity calculating unit(130) calculates whether the stored sound signal has a periodic feature at a sound frame unit. A voice detection output unit(150) outputs a voice detection signal according to the calculation result. A sample delay storage unit(160) delays and stores the sound signal as much as reference time to output the stored sound signal by synchronization with an output signal of the voice detection output unit.

    • PURPOSE: A real time face recognition apparatus is provided to automatically obtain an image coordinate of a face for an image inputted to a camera and to output a recognition result of a face in real time. CONSTITUTION: A face detector (110) obtains an image coordinate of a face from an inputted image and detects a face image. An eye detector (120) obtains a binocular image coordinate from the detected face image. A face feature extractor (130) generates feature histogram data through the parallel processing of the detected face image. A histogram matching unit (150) compares the generated feature histogram data with a comparison feature histogram in a database unit (140) and outputs the similarity of the face image.
