A 3D image-segmented evaluation procedure in a cooperative fusion system context

Abstract

This paper deals with a cooperative fusion system parameter adjustment based on an evaluation quality of the fusion system output. The concerned application is an electro- technical part quality evaluation in which geophysicists need time and experience to analyze the 3D tomography of the parts. To help them in their task, a fusion system was designed to aggregate some measurements extracted from the image. The Choquet integral was used to achieve the fusion. The adjustment of the fusion system is difficult to do by the end-user. This paper presents a procedure to guide experts in the use of the system. First of all, classified images obtained by the fusion system are evaluated. The problematic of image evaluation is addressed and an evaluation based on both quantitative and qualitative criteria is proposed. Then, some actions are defined and presented as guidelines to the expert in order to adjust the parameters in a structured way. The approach is illustrated on the classification of the 3D tomographic bloc.
