Field notes on Computer Vision, AI tooling, and engineering — what's actually changing and what's worth your attention.
From Photons to Pixels: Image Formation and Color Spaces, with OpenCV in Python and C++
How a camera turns light into an array of numbers — projection, sampling, quantization, the Bayer sensor — and the color spaces (RGB/BGR, grayscale, HSV, YCrCb, Lab) you convert between every day. The equations, plus runnable OpenCV in both Python and C++.

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. The whole shootout, numbers first.
