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.

Project mention: Show HN: Real-time privacy protection for smart glasses | news.ycombinator.com | 2025-08-11
Did you look at egoblur? its a lot more effective at face detection than https://github.com/ageitgey/face_recognition granted, you'd have to do your own face matching to do exception.

Project mention: Benchmarking ASR & Essential Open-Source CV Tools for Local AI | dev.to | 2026-06-09
Source: https://github.com/roboflow/supervision
-
EasyOCR

gaussian-splatting
Original reference implementation of "3D Gaussian Splatting for Real-Time Radiance Field Rendering"
Project mention: Gaussian Splatting – A$AP Rocky Helicopter Music Video | news.ycombinator.com | 2026-01-18This 2-minute video is a great intro to the topic https://www.youtube.com/watch?v=HVv_IQKlafQ
I think this tech has become "production-ready" recently due to a combination of research progress (the seminal paper was published in 2023 https://repo-sam.inria.fr/fungraph/3d-gaussian-splatting/) and improvements to GPU hardware/libraries.

In vmstat, watch r, wa, bi, and us plus sy together. r is runnable processes, and if it stays above your CPU core count, the CPU is saturated. wa is CPU time waiting on I/O, and sustained values above 10 to 15 during training often mean dataloader workers are blocked on disk reads. bi is blocks received from storage, and high bi with high wa points to storage bottlenecks instead of compute. us + sy is total active CPU time, and if it is high while GPU-Util is low, preprocessing is outrunning the GPU. If wa is high, increase dataloader workers or switch to faster storage. If us + sy is high with low GPU-Util, move transforms to GPU with a library such as Kornia.
