Description: 我们提出一种新方法用于单幅图像的空间变化模糊识别,在图像中的每个局部小块，这个局部模糊被选择在一个候选PSFS有限集中间，用一个极大似然方法。我们打算用广义似然减少参数的数量，用广义奇异值分解限制计算值，但是要对图像做出适当的边界假设。-We present a new approach for spatially varying blur identification
using a single image. Within each local patch in the
image, the local blur is selected between a finite set of candidate
PSFs by a maximum likelihood approach. We propose
to work with a Generalized Likelihood to reduce the number
of parameters and we use the Generalized Singular Value Decomposition
to limit the computing cost, while making proper
image boundary hypotheses. The resulting method is fast and
demonstrates good performance on simulated and real examples
originating from applications such as motion blur identification
and depth from defocus.

Description: 估计是有用的图像散焦几个应用程序 包括去模糊,模糊放大,测量图像 质量和景深分割。在本文中,我们 现在一个简单而有效的方法来评估一个分散注意力 模糊映射关系为依托的对比 图像梯度在当地的图像区域。我们把这种关系 当地的对比之前。我们的方法的优势 是,它不需要过滤银行或频率分解 输入图像 相反,我们只需要比较 当地的梯度概要文件与当地的对比。我们讨论 背后的想法之前,展示其局部对比度 在各种各样的实验效果-Image defocus estimation is useful for several applications
including deblurring, blur magnification, measuring image
quality, and depth of field segmentation. In this paper, we
present a simple yet effective approach for estimating a defocus
blur map based on the relationship of the contrast to the
image gradient in a local image region. We call this relationship
the local contrast prior. The advantage of our approach
is that it does not require filter banks or frequency decomposition
of the input image instead we only need to compare
local gradient profiles with the local contrast. We discuss
the idea behind the local contrast prior and demonstrate its
effectiveness on a variety of experiments

Description: 反锐化掩膜技术(Unsharp Masking,UM)又称为模糊蒙片处理，是一种经典的图像边缘增强算法，提高图像的高频分量部分来增强其视觉效果[18,19].反锐化掩模技术最早是应用于摄影技术中，以增强图像的边缘和细节。光学上的操作方法是将聚焦的正片和散焦的负片在底片上进行叠加，结果是增强了正片高频成份，从而增强了轮廓，散焦的负片相当于“模糊”模板（掩模），它与锐化的作用正好相反，因此，该方法被称为反锐化掩模法。(The sharpenmembrane Technology (Unsharp Masking UM) is also called fuzzy mask processing, is a classical algorithm of image edge enhancement, to enhance the visual effect of [18,19]. unsharp masking technology was first used in photography to improve the high frequency components of the image, to enhance the image edge and details. The operation method is to focus on optical negative positives and defocus are superimposed on the film, the result is the enhancement of the high frequency component of positive, so as to enhance the contours of negative defocus equivalent to "fuzzy" template (mask), and sharpening the opposite effect, therefore, this method is called unsharp masking method.)
