Improving 2D mesh image segmentation with Markov Random Fields
Sibgrap
A novel segmentation method that combines the original Imesh image-based segmentation approach with Markov Random Field (MRF) models. It takes an image as input, generate a mesh of triangles and, by treating the mesh as a Markovian field, produces quality unsupervised segmentation.
Image segmentation and cluster validation using stochastic approach
Master Dissertation
This work has carried out a study on stochastic models for segmentation and shows an implementation for the EM/MPM algorithm, together with a multiresolution approach. A new threshold-based scheme for the estimation of initial parameters for the EM/MPM model has been proposed. This work also shows how to incorporate the concept of annealing to the current EM/MPM algorithm in order to improve segmentation. Additionally, a study on the class validity problem (search for the correct number of classes) has been
