编码开关源代码，实现音响的音量控制前级输入，(Coding switch the source code to achieve sound volume control preamplifier input,)

Rician fading is a radio propagation anomaly caused by partial cancellation of a radio signal by itself — the signal arrives at the receiver by two different paths, and at least one of the paths is changing (lengthening or shortening). Rician fading occurs when one of the paths, typically a line of sight signal, is much stronger than the others. In Rician fading, the amplitude gain is characterized by a Rician distribution.

说明：  本例是一个简单的运动目标跟踪程序，对一个小球进行了实时的跟踪(This example is a simple object tracking program, for a small real-time tracking of ball)
