  • 摘要:This paper’s origin is to reach for a way for automatic initiation of shape hypothesis for Model Based Image Analysis(MBIA) in the specific case of agricultural fields. A solution is to start with local (topological) hypotheses. The topologicaldata are integrated from local topology to the level of real 2-dimensional objects. The method requires radiometric modelto generate the normalized class membership probabilities (likelihood vectors) and a minimum-size-of-object parameter.The paper gives a detailed description of the analysis approach for initiating the shape hypothesis for MBIA andbesides resolves problems related to classical approaches such as per pixel maximum likelihood classification. Anexperiment is presented about its application in a case of RGB-CCD image of agricultural fields’ model. We obtained anoverall accuracy of 97% in comparison with 83% in improved maximum likelihood classification
