Fast motion deblurring

S Cho, S Lee - ACM SIGGRAPH Asia 2009 papers, 2009 - dl.acm.org
This paper presents a fast deblurring method that produces a deblurring result from a single
image of moderate size in a few seconds. We accelerate both latent image estimation and …

Weakly supervised learning of instance segmentation with inter-pixel relations

J Ahn, S Cho, S Kwak - … of the IEEE/CVF conference on …, 2019 - openaccess.thecvf.com
This paper presents a novel approach for learning instance segmentation with image-level
class labels as supervision. Our approach generates pseudo instance segmentation labels of …

Handling outliers in non-blind image deconvolution

S Cho, J Wang, S Lee - 2011 international conference on …, 2011 - ieeexplore.ieee.org
Non-blind deconvolution is a key component in image deblurring systems. Previous
deconvolution methods assume a linear blur model where the blurred image is generated by a …

Edge-based blur kernel estimation using patch priors

L Sun, S Cho, J Wang, J Hays - IEEE international conference …, 2013 - ieeexplore.ieee.org
Blind image deconvolution, ie, estimating a blur kernel k and a latent image x from an input
blurred image y, is a severely ill-posed problem. In this paper we introduce a new patch-…

Real-world blur dataset for learning and benchmarking deblurring algorithms

J Rim, H Lee, J Won, S Cho - European conference on computer vision, 2020 - Springer
Numerous learning-based approaches to single image deblurring for camera and object
motion blurs have recently been proposed. To generalize such approaches to real-world blurs, …

Removing non-uniform motion blur from images

S Cho, Y Matsushita, S Lee - 2007 IEEE 11th International …, 2007 - ieeexplore.ieee.org
We propose a method for removing non-uniform motion blur from multiple blurry images.
Traditional methods focus on estimating a single motion blur kernel for the entire image. In …

Video deblurring for hand-held cameras using patch-based synthesis

S Cho, J Wang, S Lee - ACM Transactions on Graphics (TOG), 2012 - dl.acm.org
Videos captured by hand-held Cameras often contain significant camera shake, causing
many frames to be blurry. Restoring shaky videos not only requires smoothing the camera …

A survey of scalability solutions on blockchain

S Kim, Y Kwon, S Cho - 2018 International Conference on …, 2018 - ieeexplore.ieee.org
The blockchain is the distributed ledger technology, and the unchangeability is the main
feature. However, the scalability is hindered to satisfy the characteristic. Nowadays, there are …

MIMO relaying with linear processing for multiuser transmission in fixed relay networks

…, T Tang, RW Heath, S Cho - IEEE Transactions on …, 2008 - ieeexplore.ieee.org
In this paper, a novel relaying strategy that uses multiple-input multiple-output (MIMO) fixed
relays with linear processing to support multiuser transmission in cellular networks is …

Deblurring low-light images with light streaks

Z Hu, S Cho, J Wang, MH Yang - Proceedings of the IEEE …, 2014 - openaccess.thecvf.com
Images taken in low-light conditions with handheld cameras are often blurry due to the
required long exposure time. Although significant progress has been made recently on image …
