中文简介:
为了获取另一个图像,成像系统的质量或再现场景条件不是一种选择,计算方法提供了恢复丢失信息的有力手段。图像恢复是估计由于采集或处理系统而丢失的信息并从一组劣化图像获得具有高质量,附加信息和/或分辨率的图像的过程。目前,图像恢复的三个特定领域是高度关注的。第一个是图像恢复,盲去卷积和超分辨率,例如应用于监视,遥感,医疗和纳米成像应用,以及提高手持相机拍摄的照片质量。第二个区域是压缩感知(CS)。 CS将传统的传感过程重新定义为采集和压缩的组合,传统的解码被利用数据底层结构的恢复算法所取代。最后,新兴的计算摄影领域为许多摄影问题提供了有效的解决方案,并且还产生了用于获取和处理图像的新方法。图像恢复与计算摄影中的许多问题有关,因此,其算法在计算摄影任务中被有效地利用。此外,目前正在利用图像恢复研究来设计新的成像硬件。在本次演讲中,我们将简要概述贝叶斯建模和图像恢复的推理方法以及压缩感知和计算摄影的相关性。
课程简介: the quality of the imaging system or reproducing the scene conditions in order to acquire another image is not an option, computational approaches provide a powerful means for the recovery of lost information. Image recovery is the process of estimating the information lost due to the acquisition or processing system and obtaining images with high quality, additional information, and/or resolution from a set of degraded images. Three specific areas of image recovery are today of high interest. The first one is image restoration, blind deconvolution, and super-resolution, with application, for instance, on surveillance, remote sensing, medical and nano-imaging applications, and improving the quality of photographs taken by hand-held cameras. The second area is compressive sensing (CS). CS reformulates the traditional sensing processes as a combination of acquisition and compression, and traditional decoding is replaced by recovery algorithms that exploit the underlying structure of the data. Finally, the emerging area of computational photography has provided effective solutions to a number of photographic problems, and also resulted in novel methods for acquiring and processing images. Image recovery is related to many problems in computational photography and, consequently, its algorithms are efficiently utilized in computational photography tasks. In addition, image recovery research is currently being utilized for designing new imaging hardware. In this talk, we will provide a brief overview of Bayesian modelling and inference methods for image recovery and the very related of compressive sensing, and computational photography.
