graph structures generation using matlab

This sourcecode extracts de melcepstrum coefficient of an audio file. You should give to de function, the audio file save as a vector, and the function returns a vector with 23 melcepstrum coefficients.

姿态估计的源码，可以快速算出xyz坐标，数据可以通过matlab等进行二次开发。(Pose estimation of source code, you can quickly calculate the xyz coordinates, matlab and other data can be secondary development.)

Visual Cryptography is based on cryptography where n images are encoded in a way that only the human visual system can decrypt the hidden message without any cryptographic computations when all shares are stacked together. This paper presents an improved algorithm based on Chang’s and Yu visual cryptography scheme for hiding a colored image into multiple colored cover images. This scheme achieves lossless recovery and reduces the noise in the cover images without adding any computational complexity.

Contourlet transform and feature extraction

说明：  仿真了4种常见多径衰落信道，包括无人机信道(The four common multipath fading channel, including the uav channel)

可实现微电网中分布式电源的下垂控制，采用三环控制策略，节点既可作为V/f结点，也可作为PQ结点(It can achieve distributed generation droop control in Microgrid, which uses three-loop control strategy. The node can be used as V/f node, the node can also be used as PQ node)
