Combining multiple OCRs for optimizing word recognition

We present a method of combining multiple classifiers for optimizing word recognition. The proposed method combines the results of individual classifiers in such a way that the correct word is more likely to be hypothesized. This method provides a solution to the crucial issue of assigning reliable cost to the edges of the segmentation graph in the popular over-segmentation followed by dynamic programming approach for word recognition. Three combination functions are proposed and implemented. Experiments show that proposed method has a significant improvement on the word recognition accuracy
