代码说明:

  用fibonacci变换方法对图象做置乱或逆置乱,效率极高,在信息隐藏中属常用的方法之一。调用函数为f=fibonacci_t(I,r,s),其中参数分别为I=被置乱的图像,r=置乱密钥,s=0置乱,s=1逆置乱(Fibonacci transformation method used to do on the image or inverse Scrambling Scrambling, high efficiency in the information hidden in one of the methods are commonly used. Call the function f = fibonacci_t (I, r, s), which parameters were I = have been scrambling the image, r = scrambling key, s = 0 Scrambling, s = 1 inverse Scrambling)

    图像修复是对图像中破损区域进行信息填充,以减少图像破损所带来的信息损失的过程。 传统的图像修复方法需要依赖图像的具体结构来制定相应的修复方法,压缩感知理论的提出,使得可以利 用信号的稀疏性来对图像进行修复。基于K 奇异值分解(KSVD)与形态学成分分析(MCA,Morphological Component Analysis)的图像修复方法首先采用形态学成分分析方法对破损图像进行特征分析,将其分解 为结构部分和纹理部分;然后基于学习型字典KSVD分别对这两部分进行过完备字典训练;最后利用训练得 到的字典实现对破损图像的修复。相比于传统的图像修复方法,该方法具有适应性强、修复效果好等优点(Image inpainting is to fill the missing data in corrupted images and thus to reduce the information loss of damaged image. Traditional inpainting algorithms are dependent on specific structure of target images compressive sensing theory makes is possible to realized image inpainting with signal sparsity. This paper proposes a novel inpainting algorithm based on KSVD and MCA algorithm, which first decomposes the image into texture part and structure part, and then trains the two dictionaries for these two parts with KSVD and reconstructs the original image with these two trained dictionaries. Experiment indicates that the proposed algorithm is of better adaptability and performance as compared with traditional algorithms.)

    说明:  小波变化是对傅里叶变换和短时傅里叶变换的一个突破,其改变就在于,将无限长的三角函数基换成了有限长的会衰减的小波。(Wavelet transform is a breakthrough of Fourier transform and short-time Fourier transform. Its change lies in that the infinite trigonometric function base is replaced by the finite attenuation wavelet.)
