“…a Top category is one that is in the first 10 positions in the ranking ordered by mAP). We see that our proposal also has poor performance with the smallest queries, as the state-of-the-art system [2]. We think that the small size query problem could be tackled by considering a lower level of the pyramid, such as P 2 , to reduce the RF size and let the embedding focus mostly on the query and not also on the canvas.…”

“…2). Three important challenges come up with this particular dataset: (1) queries and documents are hand-drawn, introducing intraclass variation in the query-query and query-page relation, (2) queries are generally small (as small as ≈ 10 × 20 pixels) and (3) images are noisy and commonly degraded because all manuscripts are dated back from 10th to 16th century. 1447 possible queries among 35 different categories and 1500 pages are used for the experimentation.…”

“…No results have been reported on the first dataset so far. On the other hand, results of the authors of the second dataset showed clearly that there is room for improvement [21,22]. These two datasets are relevant to our own work and offer realistic scenarios in manuscript research, where very few labelled samples are available for each pattern to be detected (sometimes only one).…”

“…In contrast, several pattern-detection methods have been proposed to detect symbols, logos and other types of patterns found in documents [17][18][19][20]. Some of these methods have been dedicated to detecting patterns in historical documents and manuscripts [3,21,22]. This article is particularly concerned with detecting patterns in historical documents and aims to facilitate manuscript research.…”
