Abstract

In this work, the Multiresolution Fourier Transform (MFT) and Markov Random Fields (MRFs) are combined to produce as a tool for image segmentation. Firstly, a Laplacian Pyramid is used as a high-pass filter. Then, the MFT is applied in order to segment images based on the analysis of local properties in the spatial frequency domain. A methodology for edge detection in image segmentation in the Bayesian framework using Markov random field models is then developed. Stochastic Relaxation is also adopted to maximise the likelihood and find the globally minimum energy states using simulated annealing.
