Pattern Spotting and Image Retrieval in Historical Documents using Deep Hashing. (arXiv:2208.02397v1 [cs.CV])

This paper presents a deep learning approach for image retrieval and pattern
spotting in digital collections of historical documents. First, a region
proposal algorithm detects object candidates in the document page images. Next,
deep learning models are used for feature extraction, considering two distinct
variants, which provide either real-valued or binary code representations.
Finally, candidate images are ranked by computing the feature similarity with a
given input query. A robust experimental protocol evaluates the proposed
approach considering each representation scheme …
