说明：  read an image then draw it s 3D Histogram,include R and G or R and B or G and B. I have never found correct code of this before

ES is a symmetric block cipher. The same key is used to encrypt and decrypt the message. The plain text and the cipher text are the same size. The Aes algorithm works as follows: Convert to state array: This step consists of conversion on the matrix onto a state array operating with the sbox. Transformations (and their inverses) AddRoundKey: Computing the round key for each round. SubBytes: Substituting by bytes from Sbox. ShiftRows: Shifting of rows. MixColumns: Exor operation on columns. Key Expansion: Expanding the key to be used on next round.

能量检测，根据以URKOWITZ 在1967年发表的能量检测文章以及Digham 2003、Ghasemi 2007发表的一系列文章为参考， 在AWGN信道中，给定SNR下，先产生一个原始信号（单音或者BPSK基带信号），然后叠加高斯噪声， 再进行能量检测(Energy detection, according to URKOWITZ the energy released in the 1967 test articles, and Digham 2003, Ghasemi 2007 series of articles published as a reference, in the AWGN channel, for a given SNR, the first generating an original signal (mono or BPSK baseband signal), and then superimposed Gaussian noise, then the energy detection)
