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.

摘要： An exposure control method adjusts an exposure setting used for capturing an image including a foreground object and a background. The foreground object is extracted from the image by an object detection procedure. If the area of the foreground object is greater than a predetermined area value, the brightness of both the foreground object and the background is analyzed. On the contrary, if the area of the foreground object is not greater than the predetermined area value, only the brightness of the background is analyzed. The exposure setting is adjusted according to the analysis result. Accordingly, greater brightness stability is provided during the capture of the following images.

摘要： A feedback object detection method and system. The system includes an object segmentation element, an object tracking element and an object prediction element. The object segmentation element extracts the object from an image according to prediction information of the object provided by the object prediction element. Then, the object tracking element tracks the extracted object to generate motion information of the object like moving speed and moving direction. The object prediction element generates the prediction information such as predicted position and predicted size of the object according to the motion information. The feedback of the prediction information to the object segmentation element facilitates accurately extracting foreground pixels from the image.

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.

A video frame is respectively input into the video coding module and the video analysis module. The video coding module performs a coding process on the input video frame, the video analysis module analyzes the input video frame to generate a quantization parameter adjustment value, and then the video coding module adjusts each coding parameter with the quantization parameter adjustment value. In this manner, a more efficient compression can be performed on the video frame, and the compressed video frame still maintains good image quality.
