Image segmentation method combined with Markov random field (MRF) model and regional growth image in this paper is proposed to achieve the accuracy of sonar image segmentation. First of all, the characteristics of field and the label field of sonar image is established through the MRF model; secondly, the further image segmentation is processed by region growing based on the initial image segmentation...
High-level features especially free-form linear features contain more information comparing with point features, which are more useful to the latter disposal of image interpretation and surface reconstruction etc. An image matching method based on free-form linear features is proposed after the further research on description of free-form linear feature, selection of matching entity, and determination...
