Paper Abstract

In this paper we describe a model-based system for the assessment of skeletal maturity on hand radiographs by the TW2 method. The problem consists in classifiying a set of bones appearing in an image, in one of several stages described in an atlas. A first approach consisting in pre-processing, segmentation and classification independent phases is also presented. However, it is only well suited for well contrasted, low noise images, without superimposed bones, were the edge detection by zero crossing of second directional derivatives is able to extract all bone contours, maybe with little gaps, and few false edges on the background. Hence, the use of all available knowledge about the problem domain is needed to build a rather general system. We have designed a rule-based system for narrow down the rank of possible stages for each bone, and guide the analysis process. It calls procedures written in conventional languages for matching stage models against the image, and getting features needed in the classification process.
