使用对称帧差法提取运动模板，后结合背景帧差提取运动目标，二者结合进行逻辑运算，得到最终的运动目标；内部含有一个单独的函数，用于背景重构(Extracted using the symmetric difference motion template frame, combined with the background of the frame difference after the extraction of moving objects, a combination of both logic operations, the final of the moving object inside with a separate function, for background reconstruction)

this describes matlab us in image processing.

The implementation was built on Matlab/Simulink using fundamental components in Simulink to demonstrate how reliably complex modulation schemes can be built, cost effectively and efficiently [5]. The design of ZigBee transmitter using MSK modulation is shown in the Figure 1. Here we map input data bits to 8-chip PN sequences to be transmitted and results in a chip rate of two mega chips per second. After that, resultant chip sequence is send to the serial to parallel converter. It is used here to separate the odd and even bit indexed chips. Following this bipolar data formatting is performed and signal modulated with a 2.4 GHz carrier on the In Phase and QuadraturePhase data stream and adds it to get the required transmitter output signal.
