Abstract
An algorithm is described for filtering streak noise in corrupted DPCM (differential pulse code modulated) images. In this scheme, the corrupted line is detected using the Wilcoxon-Mann-Whitney nonparametric test. This test mechanism requires no PCM-update multiplexing. The corrupted line is then filtered using a likelihood ratio test and data from the previous line. Typical experimental results are provided
