对于研究FPGA结构的人来说，这个工具是必不可少的。它把edif格式的网表文件转化为blif的VPR能识别的格式，非常有用。当然，软件还需进行编译。-FPGA structure for research, this tool is indispensable. It edif netlist file format blif into the VPR to identify the format, very useful. Of course, the software still needs to be compiled.

说明：  本模型里包含几个三维模型重建的模型，对这方面感兴趣的可借鉴学习(This model contains several 3D model reconstruction models, which can be used for reference by those interested in this aspect)

说明：  主成分分析方法PCA与灰度共生矩阵GLCM 主成分分析方法是一种使用最广泛的数据降维算法。 灰度共生矩阵是一种描述图像局部区域或整体区域的某像素与相邻像素或一定距离内的像素的灰度关系的矩阵。即求灰度图像中某种形状的像素对，在全图中出现的次数。(PCA and Gray Co-occurrence Matrix GLCM The principal component analysis method is one of the most widely used data reduction algorithms. The gray level co-occurrence matrix is a matrix describing the gray level relationship between a pixel in a local area or an entire area of an image and neighboring pixels or pixels within a certain distance. That is to find the number of times a pixel pair of a certain shape appears in the whole image in a grayscale image.)

说明：  针对排列熵算法做出的改进，广义相位排列熵，通过调整参数，有效提升了排列熵算法的性能。(Aiming at the improvement of permutation entropy algorithm, generalized phase permutation entropy improves the performance of permutation entropy algorithm by adjusting parameters)
