Abstract

Segmentation of textured images, a very important aspect of visual perception, remains still a challenging task for many image analysis problems. This paper presents a recently emerged segmentation method based on the temporary correlation theory. It proposes an explanation of visual scene analysis performed by human brain. Based on this theory, a network of locally connected synchronised oscillators is proposed for the image segmentation task. This oscillator network can be realised as a VLSI chip, providing very fast image segmentation. For texture description, the Gaussian Markov Random Field model widely used in many texture analysis tasks, is applied. The proposed method is applied to segment MRI images of human foot cross-section in order to detect bone structure. This analysis could be useful in osteoporosis diagnosis, allowing further evaluation of bone microarchitecture. The efficiency of the GMRF approach in bone texture modelling is demonstrated. The oscillator network method is compared with an ANN-based classifier. The segmentation results using both methods are presented and discussed.
