Blind super-resolution restoration with frame-by-frame nonparametric blur estimation
Qian, Qinchun; Güntürk, Bahadır Kürşat (Springer, 2016)In this paper, we investigate super-resolution image restoration from multiple images, which are possibly degraded with large nonparametric motion blur. The blur kernel for each input image is separately estimated. This ... -
Extending depth of field and dynamic range from differently focused and exposed images
Qian, Qinchun; Güntürk, Bahadır Kürşat (Springer, 2016)Focus stacking and high dynamic range (HDR) imaging are two paradigms of computational photography. Focus stacking aims to produce an image with greater depth of field (DOF) from a set of images taken with different focus ... -
Space-variant blur kernel estimation and image deblurring through kernel clustering
Alam, Muhammad Zeshan; Qian, Qinchun; Güntürk, Bahadır Kürşat (Elsevier B.V., 2019)This paper presents a space-variant blur kernel estimation and image deblurring framework. For space-variant blur kernel estimation, the input image is divided into small patches, and for each patch, the blur kernel is ... -
Space-varying blur kernel estimation and image deblurring
Qian, Qinchun; Güntürk, Bahadır Kürşat (SPIE, 2014)In recent years, we have seen highly successful blind image deblurring algorithms that can even handle large motion blurs. Most of these algorithms assume that the entire image is blurred with a single blur kernel. This ... -
Super-resolution restoration of motion blurred images
Qian, Qinchun; Güntürk, Bahadır Kürşat (SPIE, 2014)In this paper, we investigate super-resolution image restoration from multiple images, which are possibly degraded with large motion blur. The blur kernel for each input image is separately estimated. This is unlike many ...
