## What it is
CascadeTabNet is a PyTorch/mmdetection implementation of a CVPR 2020 paper for end-to-end table detection and structure recognition from image-based documents. It uses a Cascade mask R-CNN HRNet model to detect table regions and recognize body cell structure in a single CNN pass.

## Use cases
- detect tables in scanned document images
- extract table structure from pdf page images
- recognize table cells in research paper screenshots
- run table detection on ICDAR 2013/2019 datasets
- benchmark table recognition models
- convert image-based tables into structured data

## When to choose
- you need state-of-the-art table detection and cell structure recognition from document images
- you want to reproduce or build on the CascadeTabNet CVPR 2020 paper
- your pipeline already uses PyTorch and mmdetection v1.2

## When to avoid
- you need a maintained production library with recent dependency support
- you work with native digital PDFs rather than image-based documents
- you cannot pin old versions of PyTorch, mmcv, and mmdetection

## Facets
- artifact type: library
- maturity: maintenance
- function: computer-vision, ocr, machine-learning, deep-learning, pdf
- domain: computer-vision, pdf, machine-learning, deep-learning
- platform: python
- tags: table-detection, table-structure-recognition, document-image-analysis, mmdetection, pytorch, research-code, linux, gpu
