2023-01-10: A Summary of "Multi-Type-TD-TSR -- Extracting Tables from Document Images using a Multi-stage Pipeline for Table Detection and Table Structure Recognition: from OCR to Structured Table Representations"
Figure 1: Detecting tables and extracting table cell structures in document image (Fig 2 in Fischer et al. ) In the past decades, several works have been published on detecting and extracting tables both from in-text-tables and tables appearing in born-digital or scanned PDF documents [ Pyreddi et al. ]. Early work focus on using heuristics such as character alignment in table images to extract tables [ Pyreddi et al. ]. Recent works involve detecting the corners of the table cells and inferring their connectivity [ Seo et al. ] in document images (see Figure 2). Figure 2: Detecting table cell corners (Fig 2 in...
