Edge Deployment Build a computer-vision plugin for OBS Studio, and measure what every frame costs
A step-by-step OBS Studio video filter in C++ on OpenVINO, split so the model swaps without touching the plumbing, and measured stage by stage: getting pixels off the GPU, where inference has to live so OBS never drops a frame, and what the trip from camera to virtual camera costs.
Evaluation Segmentation Metrics: IoU, Dice, mIoU, and Panoptic Quality
Scoring masks instead of boxes: pixel IoU/Jaccard and the Dice coefficient (and why they're related), mIoU for semantic segmentation, mask-AP for instance segmentation, and Panoptic Quality for the unified task, on one running cat-mask example, with the equations and code.
Models & Detection CNN vs Transformer, quantized: YOLO26-seg and RF-DETR-Seg race for instance masks on an Intel iGPU
Two opposite small segmentation models, a 2026-era CNN and a DETR transformer, both quantized to INT8 with NNCF and run on a laptop Intel iGPU. YOLO26-seg's forward pass is ~7.4× faster; RF-DETR-Seg keeps its masks more faithful under INT8 on the CPU, and its fully-quantized mask head breaks on the iGPU. The whole shootout, numbers first.
