Enforcing similarity constraints with integer programming for better scene text recognition
2011
CVPR 2011
Preserved Fulltext
Weinman and Learned-Miller [14] showed that the similarity among characters, as a supplement to the appearance of the characters with respect to a model, could be used to improve scene text recognition ...
In this work, we make further improvements to scene text recognition by taking a novel approach to the incorporation of similarity. ...
Acknowledgements The authors thank Jerod Weinman for the precomputed feature data and several helpful discussions. J. Feild was supported by an NSF Graduate Research Fellowship. ...

We propose a model to combine per-frame and per-track cues for action recognition. ...
With multiple targets in a scene, our model simultaneously captures the natural harmony of an individual's action in a scene and the flow of actions of an individual in a video sequence, inferring valid ...
Consequently, we can relax the binary constraint to an interval constraint and still guarantee an integer solution to the linear program. We therefore use a fast interior-point solver. ...
