Sparse Dictionary Learning for Edit Propagation of High-Resolution Images

Xiaowu Chen, Dongqing Zou, Jianwei Li, Xiaochun Cao, Qinping Zhao, Hao Zhang
2014 2014 IEEE Conference on Computer Vision and Pattern Recognition  
We introduce a method of sparse dictionary learning for edit propagation of high-resolution images or video.  ...  Previous approaches for edit propagation typically employ a global optimization over the whole set of image pixels, incurring a prohibitively high memory and time consumption for high-resolution images  ...  Edit propagation has been a well-studied problem in computer vision and it enables a variety of applications including interactive color or tonal editing, seamless cloning, and image matting.  ...

Efficient Alignment and Correspondence Using Edit Distance [chapter]

Paolo Bergamini, Luigi Cinque, Andrew D. J. Cross, Edwin R. Hancock, Stefano Levialdi, Richard Myers
2000 Lecture Notes in Computer Science  
This paper presents work aimed at rendering the dual-step EM algorithm of Cross and Hancock more efficient. The original algorithm integrates the processes of point-set alignment and correspondence.  ...  However, in its original form the algorithm uses a dictionary of structure-preserving mappings to asses the consistency of match. This proves to be a serious computational bottleneck.  ...  Introduction The matching of point-sets is a problem of central importance in computer vision, The process is usually abstracted as either alignment or correspondence.  ...

A Learning-Based Approach to Reduce JPEG Artifacts in Image Matting

Inchang Choi, Sunyeong Kim, Michael S. Brown, Yu-Wing Tai
2013 2013 IEEE International Conference on Computer Vision  
Single image matting techniques assume high-quality input images. The vast majority of images on the web and in personal photo collections are encoded using JPEG compression.  ...  To address this situation, we propose a learning-based post-processing method to improve the alpha mattes extracted from JPEG images.  ...  Introduction Single image matting is a problem that has been extensively studied in computer vision and graphics.  ...

Bayesian graph edit distance

R. Myers, R.C. Wison, E.R. Hancock
2000 IEEE Transactions on Pattern Analysis and Machine Intelligence  
The paper develops the idea of edit-distance originally introduced for graph-matching by Sanfeliu and Fu [1] .  ...  The use of edit-distance offers an elegant alternative to the exhaustive compilation of label dictionaries. Moreover, the method is polynomial rather than exponential in its worst-case complexity.  ...  The first of these is the complexity of computing the distance measure. The second is the number of distance computations that must be performed.  ...
