Description: 图像修复是图像处理的一个重要问题。这是一个困难的问题,同时填写在地区缺少图像信息的纹理和结构。以损坏的图像inpaint失踪的结构和纹理信息,基于小波分解的图像修补算法提出。首先损坏的图像分解成子图像和纹理结构,利用小波子图像转变。然后,地区结构中缺少的信息的子图像重建曲率驱动扩散(CDD),算法,而在同一区域的纹理子图像填写基于改进的纹理合成的典范 最后,恢复的图像,通过重组,结构和纹理恢复的结果。大量的实验表明,该算法可以快速,高效地恢复在同一时间的结构和纹理信息,视觉效果和峰值信噪比比(PSNR)比同类算法更好。-Image inpainting is an important problem image processing. It is a difficult problem to simultaneously fill-in the
texture and structure in regions of missing image information. In order to inpaint the damaged image with both
missing the structure and texture information, an image inpainting algorithm based on wavelet decomposition is
presented. First the damaged image is decomposed into structure sub-image and texture sub-image using the wavelet
transformation. Then, the sub-image with the region of missing information in the structure is reconstructed by
Curvature-Driven Diffusions (CDD) algorithm, while the same region in the texture sub-image is filled-in with the
improved texture synthesis based on exemplar Finally, the restored image is given by recombining the structure and
texture restored results. A large number of experiments show that the proposed algorithm can quickly and efficiently
restore the structure and texture information at the same time, and the visual eff Platform: |

Inpainting using sparse regularization. Consider the pepper image with many missing
pixels.
Assume that the image is noisy-free.
(a) Inpaint the image by using orthogonal wavelet sparsity.
(b) Inpaint the image by using a different sparsity prior.
Based on the outputs, it is clear that the inpainting result obtain by Sobolev is much better than
other methods (i.e. Orthogonal wavelet sparsity and Invariant wavelet sparsity). -For using this code need to use signal toolbox and general toolbox in your matlab

-Image inpainting refers to restore the color information of the damaged region in the image or remove the
unnecessary object in the image. A method is introduced to compute the main direction of the texture and complete
the image based on wavelet transform. The core of the algorithm relies on using texture detection in a coarse-to-fine
scheme. Experimental results show that the algorithm can obtain the satisfied restoration video frames.

Description: 本文提出一种基于边缘自适应小波变换的多尺度图像修复算法,对非纹理图像有比较好的修复效
果。边缘自适应小波变换的基本思想是,先检测出图像的主要边缘,这些边缘把图像分割成几个平滑区,然后
对图像进行不跨越边缘的小波分解,即在各平滑区内部进行小波变换,得到图像的多尺度表示,并且同时计算
边缘的多尺度表示。这样的小波分解使高频信息基本都集中在边缘上,而高频系数则非常稀疏,而且都接近
于零。在此基础上进行图像修复,就只需要对低频部分与边缘图像进行修复,然后重构得到修复图像即可。
经过小波分解,低频部分破损区域大大缩小,用比较简单的插值方法就可进行修复,大大降低了计算量。对边-Abstract:A fast inpainting algorithm based on edge—adaptive wavelet transform are in—

Description: 传统的图像修复算法速度慢, 对大面积的破损区域修复效果较差. 本文针对
这一缺点, 首先对待修复图像进行小波分解, 使得图像的破损区域在低频部分留下

的破损区域, 再利用低频信息来预测相应的高频信息, 最后进行小波重构, 并对受
损部分进行自然化处理, 得到修复的图像. 仿真实验结果表明, 本文提出的算法速
