The problematic of automatically searching series of broad patterns in technical documents is studied. Such series can be assumed to ordered information useful for the understanding of documents. The proposed methodology is able to extract successive patterns of different natures without a priori information. To make this, we consider the spatial location of triplets of similar connected components using force histogram and the recognition is performed by considering surrounding discrete lines. This new model is fast and it allows a good extraction of occulted patterns in presence of noise while requiring only few thresholds, which can be automatically set from data.
