• Abstract: Logical page segmentation is an important step in document analysis, enabling better semantic representations, information retrieval, and text understanding. Previous approaches define logical segmentation either through text or geometric objects, relying on OCR or precise geometry. To avoid the need for OCR, we define the task purely as segmentation in the image domain. Furthermore, to ensure the evaluation remains unaffected by geometrical variations that do not impact text segmentation, we propose to use only foreground text pixels in the evaluation metric and disregard all background pixels. To support research in logical document segmentation, we introduce TextBite, a dataset of historical Czech documents spanning the 18th to 20th centuries, featuring diverse layouts from newspapers, dictionaries, and handwritten records. The dataset comprises 8,449 page images with 78,863 annotated segments of logically and thematically coherent text. We propose a set of baseline methods combining text region detection and relation prediction. The dataset, baselines and evaluation framework can be accessed at https://github.com/DCGM/textbite-dataset.

  Document Screenshot Embedding (DSE) is a novel retrieval paradigm that regards document screenshots as a unified input format.<n>We first craft the dataset of Wiki-SS, a 1.3M Wikipedia web page screenshots as the corpus to answer the questions from the Natural Questions dataset.<n>For example, DSE outperforms BM25 by 17 points in top-1 retrieval accuracy. Additionally, in a mixed-modality task of slide retrieval, DSE significantly outperforms OCR text retrieval methods by over 15 points in nDCG@10.

  Document semantic segmentation can facilitate document analysis tasks, including OCR, form classification, and document editing. Several synthetic datasets have been developed to distinguish handwriting from printed text, but they fall short in class variety and document diversity. We propose the most comprehensive document semantic segmentation pipeline to date, incorporating preprinted text, handwriting, and document backgrounds from over 10 sources. Our customized dataset exhibits superior performance on the NAFSS benchmark, demonstrating it as a promising tool in further research.

  We tackle open-world semantic segmentation, which aims at learning to segment arbitrary visual concepts in images.

We propose a novel Text-grounded Contrastive Learning framework that enables a model to directly learn region-text alignment.

We show that current state-of-the-art text-recognition (OCR) models fail to perform well on TextOCR. We use a TextOCR trained OCR model to create PixelM4C model which can do scene text based reasoning on an image in an end-to-end fashion.

• Scene Text Retrieval via Joint Text Detection and Similarity Learning [68.24531728554892]
  Scene text retrieval aims to localize and search all text instances from an image gallery, which are the same or similar to a given query text. We address this problem by directly learning a cross-modal similarity between a query text and each text instance from natural images. In this way, scene text retrieval can be simply performed by ranking the detected text instances with the learned similarity.
