CONFIRM – Clustering of noisy form images using robust matching
2019
Pattern Recognition
Preserved Fulltext
This work presents a novel algorithm: CONFIRM (Clustering Of Noisy Form Images using Robust Matching), which simultaneously discovers the types in a collection of forms and assigns each form to a type. ...
CONFIRM matches type-set text and rule lines between forms to create domain specific features, which we show outperform Bag of Visual Word (BoVW) features employed by the current state-of-the-art. ...
This work presents CONFIRM (Clustering Of Noisy Form Images using Robust Matching), an approach which performs unsupervised form type discovery and assignment in the presence of significant noise. ...

We present deep spectroscopic measurements of 18 distant field galaxies identified as gravitationally-lensed arcs in a Hubble Space Telescope image of the cluster Abell 2218. ...
Redshifts of these objects were predicted by Kneib et al. (1996) using a lensing analysis constrained by the properties of two bright arcs of known redshift and other multiply-imaged sources. ...
ACKNOWLEDGMENTS We thank Mike Breare and all the La Palma support sta for ensuring the smooth operation of LDSS-2 on the WHT. We especially thank Karl Glazebrook for the use of his RED-SHIFT utility. ...

This dramatically moves back the time at which we know short bursts were being formed, and suggests that the present evidence for an old progenitor population may be observationally biased. ...

Our findings are consistent with theoretical predictions of a PopIII wave, with PopIII star formation migrating away from the original sites of star formation. ...
