This paper presents the evaluation of a number of algorithm alternative for content based retrieval from a database of technical drawings representing patents. The objective is to help patent evaluator in their quest for a possible patent bearing too much similarity with the one under investigation. To achieve this, we have devised a system where images (drawings) are represented using attributed graphs based on the extracted line-patterns or histograms of attributes computed from the graphs.
