Description: In this study, approaches of image enhancement, edge extraction, and
line-based image matching for remote sensing images are proposed. The
image enhancement includes noise reduction and contrast enhancement. We
apply wavelet shrinkage techniques to suppress noise while preserving the
sharpness of large-scale edges based on a Teager energy operator. Platform: |

Description: BM3D算法源代码。NLM去噪算法使用的是inter-patchcorrelation，而Wavelet shrinkage使用的则是intra-patch correlation。这两种方法都取得了不错的效果，一个很自然的想法就是：可以同时使用他们两个方法吗？这便导出了BM3D去噪算法[2]，算是现在公认的去噪效果最好的算法。-BM3D algorithm source code. NLM Denoising algorithm using inter-patchcorrelation, and Wavelet shrinkage is the use of intra-patch correlation. Both of these methods have achieved good results, a very natural idea is: You can use them both ways? This has derived BM3D denoising algorithm [2], regarded now recognized as the best de-noising algorithm. Platform: |
