The performance of a maximum entropy image restoration scheme due to Burch et al. (1983) and Gull and Daniell (1978) is considered in quantitative terms as follows. By means of a random number generator, it is possible to obtain data samples of a given signal contaminated with noise of known characteristics. Each of these data samples is then processed by the restoration scheme. For simple signal patterns, it is found that the majority of samples bear less resemblance (in terms of chi squared) to the original signal after being 'restored'.
