Image Enhancement. Takes lenna image as input, applies low pass filter, median filter, weighted and center weighted median filter. Plots the output for each image

说明：  Emotion modeling and recognition has drawn extensive attention disciplines such as psychology, cognitive science, and, lately, engineering. Although a significant amount of research has been done on behavioral modalities, less explored characteristics include the physiological signals.

在MATLAB中实现图像的局部二值模式处理，运行test函数即可使用。(Achieve a partial image in MATLAB binary mode processing, running test functions can be used.)

说明：  基于倒谱法的基音周期检测，有着不错的参考意义。(The pitch period detection based on cepstrum method has a good reference value.)

It provides some examples in numerical analysis using Matlab like solving polinomies, solution on nonlinear equations, etc.

Voltage sags are one of the main problems in transmission and distribution grids with high penetration of distributed generation. This paper proposes a voltage support control scheme for grid-connected power sources under voltage sags. The control is based on the injection of reactive current with a variable ratio between positive and negative sequences. The controller determines, also, the amount of reactive power needed to restore the dropped voltage magnitudes to new reference values confined within the continuous operation limits required in grid codes. These reference values are chosen in order to guarantee low current injection when fulfilling the voltage support objective. Selected experimental results are reported in order to validate the effectiveness of the proposed control.
