An optimal filter is estimated to restore binary fax images. The filter is an approximation of the binary conditional expectation which minimizes the expected absolute error between the degraded image and the ideal image. It is implemented as a morphological hit-or-miss filter. Estimation methodology employs a model-based simulation of the degradation due to the fax process.
