代码说明:

  dct隐写技术matlab实现资料。算法原理:通过在一个图像块中调整两个DCT系数的相对大小,隐藏秘密信息。 将载体图像分为8×8的块,做二维DCT变换 用来表示选中的两个系数的坐标对于第i bit秘密信息 if(要隐藏信息‘1’) make else make 逆DCT变换,还原图像 (dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)

  • DCM_H
    用C语言编写的在Simulink环境下对转速可调永磁直流电机进行数值仿真的S函数源代码。该仿真源代码的特点是:能够仿真目前广泛应用的H桥驱动PWM调制调速永磁直流电机。将功率器件H桥与电机本体的数学模型完整的结合到一起。执行效率很高,仿真结果与实验结果非常相近。(C language in the Simulink environment for adjustable speed permanent magnet DC motor simulation S-function source code. The simulation source code features : simulation can be widely applied to the H-bridge PWM drive permanent magnet DC motor speed control. Will power devices H-bridge and motor Ontology integrity of a mathematical model combining together. High efficiency in the implementation of simulation results and experimental results are very similar.)
