Abstract
In this paper, we introduce a pattern matching algorithm used in document image compression. This pattern matching algorithm uses the cross entropy between two patterns as the criterion for a match. We use a physical model which is based on the finite resolution of the scanner (spatial sampling error) to estimate the probability values used in cross entropy calculation. Experimental results show this pattern matching algorithm compares favorably to previous algorithms.
