摘要： A particle filter is suitable for performing particle filtering on a frame to track a particular object in the frame. The particle filter includes a frame cache, an observation model generator, and a particle filter controller. The frame cache is connected to a system memory through a system bus, in which the system memory stores all image blocks of the frame; and the frame cache obtains the at least one image block of the frame from the system memory and stores the obtained image block. The observation model generator reads at least one pixel from the frame cache, and generates an observation model corresponding to the object and the read image block according to the read pixel. The particle filter controller obtains the observation model from the observation model generator, and determines and outputs an object tracking result of the object according to the observation model.

摘要： A sound source monitoring system includes a sound receiving module, a sound detection module, a sound source localization module, and a camera module. The sound receiving module is configured to receive a plurality of sound signals. The sound detection module is for dividing an integrated signal formed by adding the sound signals received by the sound receiving module and normalizing the sum of the sound signals or dividing each of the sound signals into a plurality of sub-bands, calculating a signal-to-noise ratio (SNR) of each sub-band and a background noise, and accordingly determining whether to output the sound signals received by the sound receiving module to the sound source localization module. The sound source localization module is for outputting a sound source location by using the sound signals received by the sound receiving module. The camera module is for shooting an image corresponding to the sound source location.
