ABSTRACT:
Enhancement of contours in images that are noisy or otherwise corrupted is important in medical imaging, scanning for weapons detection, and many other fields. Here, the Curve Indicator Random Field (CIRF) is used as a model of uncorrupted images of contours for constructing filters with biased CIRF posterior mean approximations involving a coupled nonlinear system of equations with a number of adjustable parameters.
