    Abstract: A sound source localization system includes a microphone array composed of a plurality of microphones each converting sound wave into a corresponding voice signal; a room shape estimator that determines a room shape including a location map and a corresponding template voice feature map composed of template voice features associated with a virtual sound source disposed at different locations respectively, and outputs a room reliability indicating confidence about the determined room shape; a lookup table (LUT) that pre-stores the location map and the corresponding template voice feature map; and a localizer that determines a location of a sound source according to the room reliability and similarity between a voice feature associated with the sound source and the template voice features of the template voice feature map.

    Abstract: A monitoring device and an operation method thereof are provided to detect whether an object of interest appears in a video stream. The monitoring device includes a motion calculation circuit, a motion region determination circuit and a computing engine. The motion calculation circuit performs motion calculation on a current frame in the video stream to generate a motion map. The motion region determination circuit determines a motion region in the current frame according to the motion map. The motion region determination circuit notifies the computing engine with the motion region in the current frame. The computing engine performs an object of interest detection on the motion region in the current frame of the video stream to generate a detection result. The motion region determination circuit determines whether to ignore the motion region in a subsequent frame after the current frame according to the detection result.
