项目介绍

DeepRFT(Deep Residual Fourier Transformation)是一个用于单张图像去模糊的开源项目。该项目基于深度学习技术,利用残差傅里叶变换对图像进行去模糊处理,提高了去模糊的效率和效果。DeepRFT不仅在理论研究中表现出色,而且在实际应用中具有很高的实用价值。

项目技术分析

DeepRFT的核心技术是残差傅里叶变换。该技术通过将图像转换到频域,对高频部分进行处理,再转换回空域,从而实现图像的去模糊。残差学习则用于优化变换过程中的损失,提高去模糊的准确性。

项目的网络架构如图所示,主要包括输入层、多个残差块、傅里叶变换层和输出层。这种架构不仅保证了模型的可扩展性,而且使得模型能够有效学习图像的频域特征。

When we use a camera, we want the recorded image to be a faithful representation of the scene that we see, but every image is more or less blurry. In image deblurring, the goal is to recover the original, sharp image by using a mathematical model of the blurring process. The key issue is that some information on the lost details is indeed present in the blurred image, but this “hidden” information can be recovered only if we know the details of the blurring process. Deblurring Images: Matrices, Spectra, and Filtering describes the deblurring algorithms and techniques collectively known as spectral filtering methods, in which the singular value decomposition—or a similar decomposition with spectral properties—is used to introduce the necessary regularization or filtering in the reconstructed image. The concise MATLAB® implementations described in the book provide a template of techniques that can be used to restore blurred images from many applications. This book’s treatment of image deblurring is unique in two ways: it includes algorithmic and implementation details; and by keeping the formulations in terms of matrices, vectors, and matrix computations, it makes the material accessible to a wide range of readers. Students and researchers in engineering will gain an understanding of the linear algebra behind filtering methods, while readers in applied mathematics, numerical analysis, and computational science will be exposed to modern techniques to solve realistic large-scale problems in image processing. With a focus on practical and efficient algorithms, Deblurring Images: Matrices, Spectra, and Filtering includes many examples, sample image data, and MATLAB codes that allow readers to experiment with the algorithms. It also incorporates introductory material, such as how to manipulate images within the MATLAB environment, making it a stand-alone text. Pointers to the literature are given for techniques not covered in the book. Audience This book is intended for beginners in the field of image restoration and regularization. Readers should be familiar with basic concepts of linear algebra and matrix computations, including the singular value decomposition and orthogonal transformations. A background in signal processing and a familiarity with regularization methods or with ill-posed problems are not needed. For readers who already have this knowledge, this book gives a new and practical perspective on the use of regularization methods to solve real problems.
