Script-agnostic reflow of text in document images

Saurabh Panjwani, Abhinav Uppal, Edward Cutrell
2011 Proceedings of the 13th International Conference on Human Computer Interaction with Mobile Devices and Services - MobileHCI '11  
We present a technique that reflows text in document images in a manner that is agnostic to the script used to compose them.  ...  Reading text from document images can be difficult on mobile devices due to the limited screen width available on them.  ...  The Reflow Process Once words have been identified in a document image, reflowing them to fit a given width is relatively easy.  ...

1998 Circulation  
Methods and Results-Seven dogs underwent 90-minute balloon occlusion of the left anterior descending coronary artery (LAD) followed by reflow.  ...  These results are consistent with progressive microvascular and myocardial injury well beyond coronary occlusion and reflow. (Circulation. 1998;98:1006-1014.)  ...  study documents a progressive increase in the extent of no-reflow regions beyond a few hours after reperfusion relative to infarct size.  ...

and may therefore be better classified as myocardial infarction reperfusion no-reflow (whether it is documented by angiography or by the more sensitive myocardial imaging techniques).  ...  Other myocardial imaging techniques such as nuclear magnetic imaging and positron emission tomography have also been shown to be useful diagnostic tools for no-reflow [36] [37] [38] .  ...

2005 Journal of Echocardiography  
LV end-diastolic volume index (LVEDVI) at pre-discharge was significantly higher in the no-reflow group than the reflow group (64 17 vs. 58 11 mL/m 2 , p< 0.01).  ...  The no-reflow group had a higher CRP level and peak monocyte counts than the reflow group (9.5 5.2 vs. 5.8 3.5 mg/dl, p<0.0001; and 1026 400 vs. 824 278/ l, p<0.001, respectively).  ...  Comparison between two groups was performed Reflow No-reflow In the image on the left, myocardial perfusion was well preserved in all myocardial segments.  ...

2004 Journal of the American College of Cardiology  
Microvascular obstruction and infarct size by first-pass and delayed contrast-enhanced magnetic resonance imaging (MRI) were measured at 1 and 24 h after reperfusion and compared with postmortem infarct  ...  BACKGROUND Microvascular obstruction or "no-reflow" (MO) has been shown to negatively influence left ventricular (LV) remodeling after myocardial infarction (MI).  ...  We found a very good correlation between no-reflow defined by microspheres and MRI, as previously documented in our earlier work (5, 28) .  ...

2001 Journal of the American College of Cardiology  
The CFIp was significantly higher in patients with MCE no-reflow (n ϭ 16) than in those with MCE reflow (n ϭ 32) (0.34 Ϯ 0.07 vs. 0.23 Ϯ 0.06, p Ͻ 0.01).  ...  It remains unknown whether CFIp also identifies collateral function in AMI patients with and without no-reflow phenomenon. METHODS The study population included 48 patients with a first AMI.  ...  An operator who did not know the patients' data analyzed the MCE images.  ...
