Frame difference is arguably the simplest form of background subtraction. The current frame is simply subtracted from the previous frame, and if the difference in pixel values for a given pixel is greater than a threshold Ts, the pixel is considered part of the foreground.

GSC為一數值演算的方法，用於求最佳值，經由反覆的演算求得最佳的結果(GSC is a numerical calculation method for seeking the best value, obtained by repeated calculation of the best results)

说明：  用matlab编的Capon算法和延迟相加法的程序，能够实现不同信号入射时的DOA估计，从而可以比较两种算法的分辨率等(Used for the Capon algorithm matlab and delays add up to the law of procedure, to achieve different signal DOA estimates at the time of the incident, which can compare the two algorithms, such as the resolution)
