A model for evaluating the effectiveness of resolution enhancement algorithms

摘要

This model, based upon the binary symmetric channel of information theory, regards an array of optical sensors and subsequent enhancement algorithms as a binary information system. A single bit of information is assumed to be produced by each sensor in the optical array. In the enhancement scheme, each bit is replaced by several estimated bits. This model relates the effective system channel capacity to the number of sub-areas of each sensor to be estimated, and to the error rate involved in making these estimates. The error rate obtained for a simple enhancement algorithm is examined using the criterion developed in this model.
