[Special Effects] Analyzing-Spatially-varying-Blur DL : 0: 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.

[Special Effects] estimate-the-defocus-map-in-an-image DL : 0: 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
