Silhouette estimation

J Opt Soc Am A Opt Image Sci Vis. 2014 Jul 1;31(7):1636-44. doi: 10.1364/JOSAA.31.001636.

Abstract

Silhouettes arise in a variety of imaging scenarios. Pristine silhouettes are often degraded via blurring, detector sampling, and detector noise. We present a maximum a posteriori estimator for the restoration of parameterized facial silhouettes. Extreme dealiasing and dramatic superresolution, well beyond the diffraction limit, are demonstrated through the use of strong prior knowledge.
