ABSTRACT:
A word recognizer system 10 has a probabilistic relaxation process that improves the performance of an image text recognition technique by propagating the influence of word collocation statistics. Word collocation refers to the likelihood that two words co-occur within a fixed distance of one another. The word recognizer 10 receives groups of visually similar decisions (called neighborhoods) for words in a running text. The position of decisions within the neighborhoods are modified based on how often they co-occur with decisions in the neighborhoods of other nearby words. This process is iterated a number of times effectively propagating the influence of the collocation statistics across an input text.
