| Abstract(in English) | For visual image processing, coupled Markov random field (MRF) models have been proposed, and they are classified into boundary-based and region-based models, according to the interactions between the nodes corresponding to the image pixels. The original region-based MRF models have a local-minimum problem because of its discrete hidden variables, but an improved model has been proposed by introducing phase variables as continuous hidden variables to solve this problem. We have already modified this model by introducing piecewise linear (PWL) functions to simplify the model towards its VLSI implementation. In this paper, we investigate the controllability of the parameters of PWL functions, and evaluate the performance in the application of coarse image region segmentation. We have verified that the segmentation tuning and the processing speed can be improved by optimizing of the parameters. |
