The goal of adaptive image processing is to suppress noise while enhancing structure. This requires some method of discriminating between signal and noise within a local region. Variance estimates, which are popular for such a task, indicate signal activity but do not discriminate signal from noise. Directional variance estimates are experimentally evaluated using synthetic test images
