Paper Abstract

Parameter studies for Markov random field (MRF) models of early vision performed using a DAP array processor are discussed. A simple two-dimensional formulation for MRFs with coupled line processes on a rectangular grid is analyzed. Numerous experimental results are presented for real and synthetic intensity images. We empirically analyze the interrelationships between parameters controlling the degree of smoothness in the solution, the discontinuity threshold, and the importance of input data. Trends are identified, especially with regard to methods for automatically setting parameters. In addition, a comparison of results across different resolutions is made.
