On the basis of image cross correlation of brightnessdistribution and Fast Fourier Translation, the implementation of Particle image Velocimetry was studied.
在图像灰度分布互相关和快速傅立叶变换的基础上，研究了粒子图像测速的实现。

The principle is to impose multiple differential operators on facial region, which highlights the nearby area of the facial organs and form many high-brightnessdistribution areas.
其原理是将多次微分运算施加于肖像的脸部区域，从而突显出脸部的高亮度分布区。

In the backlight module, this process is achieved through the light guide plates. The key of the design is to find a reasonable distribution of nodes to obtain uniform brightnessdistribution.
