matlab图像去模糊算法代码
说明: matlab图像去模糊算法代码,使用两倍长度的点扩散函数进行维纳滤波,模糊图像加入随机噪声,计算噪声信号功率比,使用噪声能量和图像一维自相关函数进行维纳滤波,模糊后的图像,减小噪声能量进行规则化滤波,增大拉格朗日乘子进行滤波,继续对恢复的图像反卷积,产生模糊图像,最初的PSF,显示最初PSF下恢复的PSF。(MATLAB image deblurring algorithm code, using double-length point spread function for Wiener filtering, adding random noise to blurred image, calculating noise signal power ratio, using noise energy and image one-dimensional autocorrelation function for Wiener filtering, blurred image, reducing noise energy for regular filtering, increasing Lagrange multiplier for filtering, continue to restore the image. Like deconvolution, a blurred image is generated. The original PSF displays the restored PSF under the original PSF.)

MbufAllocColor
这个函数分配一个数据缓冲区与多个颜色指定系统上的乐队。这种类型的缓冲区允许表示彩色图像(例如,RGB)。
这个函数为每个指定分配缓冲区,一个二维表面颜色乐队。您可以使用MbufAlloc1d()和MbufAlloc2d()来创建单独的乐队一或二维
数据缓冲区,分别。
分配一个缓冲区后,我们建议您检查是否操作成功,使用MappGetError(),或通过验证,不是M_NULL返回的缓冲区的标识符。(This function allocates a data buffer with multiple color bands on the specified system. This type of buffer allows for the representation of color images (for example, RGB).
This function allocates buffers that have a two-dimensional surface for each specified color band. You can use MbufAlloc1d() and MbufAlloc2d() to create single band one- or two-dimensional
data buffers, respectively.
After allocating a buffer, we recommend that you check if the operation was successful, using MappGetError(), or by verifying that the buffer identifier returned is not M_NULL.)

chaos_logistic
说明: 在产生混沌伪随机序列的混沌映射中,Logistic映射(Logistic Map)是一种简单而经典的映射。其中u称为分形参数,随着u逐渐增大,出现倍周期分岔现象。可用于密文域图像加密。(Logistic Map is a simple and classical mapping for generating chaotic pseudo-random sequences. U is called fractal parameter, and with the increase of u, period doubling bifurcation occurs. It can be used for image encryption in ciphertext domain.)
