OpenCV Web Document Scanner v1.3.3 – Release Notes

Date: 2025-09-14

Highlights

  • WebGL Preprocessing (PoC): Optional grayscale + 3×3 blur via shader, toggle in UI; safe CPU fallback; core detection unchanged
  • Performance Test Tool: Timed runs with periodic PERF_SNAPSHOT logs and final VALIDATION_SUMMARY
  • Client Log Uploads: Full client debug log per test uploaded to /save-client-log into versions/v1.3.3/test-logs/
  • Overlay Accuracy Fixes: Canvas aligned 1:1 to video pixels, corrected mapping (no left/right margins)

Changes

  • UI: Added top-right toggles (WebGL PoC, Test Mode, Perf Test)
  • JS: Robust OpenCV ready; idempotent WebGL init; improved error hooks; per-window perf counters (WebGL vs CPU)
  • Server: Python HTTPS (TLS ≥ 1.2) with /log, /save-image, /save-client-log, log rotation (5MB), no-cache headers
  • Docs: Updated README and VERSION for v1.3.3; added this release notes file

Observations

  • Initial measurements show CPU baseline (~71–75 ms/frame) faster than WebGL PoC (~85 ms/frame) on tested devices; PoC remains optional
  • Quality toggles (downscale/extra blur) were tested and reverted to restore stable detection quality

How to run

cd versions/v1.3.3
openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 365 -nodes \
  -subj "/C=DE/ST=State/L=City/O=Organization/OU=OrgUnit/CN=localhost"
python3 server.py

Open https://localhost:8000 (accept self-signed cert), use the top-right toggles for tests.
