1. ultralytics

   1 38 58,307 9.9 Python

   Ultralytics YOLO 🚀

   

   Project mention: Transforming Unstructured Retail Catalogs into Structured Data using AI | dev.to | 2026-04-10

   Before reading any text, we run the raw catalog pages through a custom object detection model (based on YOLO architecture). This model is trained to identify the bounding boxes of individual product regions, allowing us to crop the giant page into smaller, isolated product images.

5. mmdetection

   4 24 32,695 5.8 Python

   OpenMMLab Detection Toolbox and Benchmark

   

   Project mention: PYX: The next step in Python packaging | news.ycombinator.com | 2025-08-13

   There certainly are issues on Linux as well. The Detectron2 library alone has several hundred issues related to incorrect versions of something: https://github.com/facebookresearch/detectron2/issues

   The mmdetection library (https://github.com/open-mmlab/mmdetection/issues) also has hundreds of version-related issues. Admittedly, that library has not seen any updates for over a year now, but it is sad that things just break and become basically unusable on modern Linux operating systems because NVIDIA can't stop breaking backwards and forwards compatibility for what is essentially just fancy matrix multiplication.

    Project mention: From 9 Tiles to 900: Scaling Computer Vision Pipelines | dev.to | 2026-06-04

    Tiled inference isn't a niche technique. It's the industry standard for any image that exceeds a model's input constraints. SAHI (Slicing Aided Hyper Inference) has over 35,000 stars on GitHub. It partitions images into overlapping slices, runs detection on each slice, and stitches results together. Digital pathology pipelines routinely tile gigapixel whole-slide images into thousands of patches for parallel inference. Satellite imagery processing architectures on AWS all involve the same core pattern: tile, infer in parallel, aggregate.

24. AdelaiDet
