摘要

利用反卷积问题,设计了许多算法来消除由相机抖动引起的图像模糊,无论是一个或多个输入图像。如果摄影师拍摄了一组图像,这是几乎所有现代数码相机都有的一种模式,那么将所有图像组合在一起就有可能得到一个清晰的版本。该算法不使用模糊估计及其逆问题。所提出的算法非常简单,其中平均权值是使用傅里叶域计算的,这取决于傅里叶谱的幅度。在这里,图像的突发被考虑和每个图像的突发模糊不同。提出的傅立叶突发积累算法表明,将不同模糊程度的图像组合在一起可以得到清晰的图像。这可以在现代智能手机中实现。

Aggregation of blurred images through weighted FBA to remove camera shake
Many algorithms were designed to remove image blur due to camera shake, either with one or multiple input images, by using the deconvolution problem. If the photographer takes a burst of images, a modality available in virtually all modern digital cameras, it is possible to combine all the images to get a clean sharp version. This algorithm does not use blur estimation or its inverse problem. The proposed algorithm is strikingly simple where the average weight is calculated using Fourier domain which depends on the Fourier spectrum magnitude. Here, burst of images are taken into an account and each image in the burst is blurred differently. The proposed Fourier burst accumulation algorithm shows that one can obtain a sharp image by combining all the images together which is blurred differently. This can be implemented in modern smart phones.
