substitution cipher is the method of encoding in which unit of plain text are replaced by cipher text. Monoalphabetic cipher uses a fixed message over entire message.A monoalphabetic cipher uses fixed substitution over the entire message.The monoalphabetic substitution takes a letter of an alphabet and substitutes it with another letter, this way a ciphertext is generated. The way of converting is fixed. A character of the plaintext will be replaced by the same ciphertext character, during the entire ciphertext. There is no additional key. The only way of security is to keep the substitution-table secret. A popular example for the monoalphabetic substitution is the caesar cipher.

说明：  实现rgb图像向hsi图像的转换，以便更好的反应人的视觉特性。(Rgb images to achieve the conversion to hsi image in order to better reflect the human visual characteristics.)

说明：  针对Hénon map,找出其稳定点，. 以及在参数确定的情况下绘画出其分岔图，计算李雅普诺夫指数，最后做出时域图 (For Hénon map,1) Find the fixed points of periods one and two for the Hénon map. 2) Investigate the bifurcation diagrams for the Hénon map by plotting the x_n values as a function of α for β = 0.4. 3) Write a Matlab or Maple program to compute the Lyapunov exponents of the Hénon map where α=1.2 and β = 0.4. 4) Use the OGY algorithm to stabilize a point of period one in the Hénon map where α=1.2 and β = 0.4.)
