plumbking 0.1.1

Classical CV-based image leveling and thumbnail generator.

PlumbKing 👑 — Classical CV Image Leveling & Thumbnails

PlumbKing is a lightweight, classical-CV horizon leveling and thumbnail generator. It processes photo batches using a purely deterministic pipeline:

• Multi-scale K-Means segmentation
• Canny edge extraction
• Probabilistic Hough transform
• Weighted roll voting
• Optional RANSAC horizon correction

No ML models, no cloud calls — just fast, transparent image geometry.

---

✨ Features

• 📐 Automatic roll leveling (multi-scale classical CV)
• 🔍 Preview mode with confirmation before replacing originals
• 🧭 EXIF-aware rotation correction
• 🖼️ Structured thumbnail generation
• 🛠️ Debug output for each stage (--debug-dir)
• 🐧 Works on Linux, macOS, WSL

---

🚀 Installation

pip install plumbking

---

📦 Basic Usage

Level and thumbnail all images in a directory:

plumbking --directory /path/to/images

Dry-run (no writes):

plumbking --directory /path/to/images --dry-run

Enable full CV debug logging:

plumbking --directory /photos --debug-dir /tmp/pk-debug

This creates per-image folders containing:

• segmentation maps
• Canny edge maps
• Hough overlays
• RANSAC boundary maps
• intermediate resized crops

---

🔧 Workflow Summary

1. Scan the directory

2. Detect leveling candidates

3. Generate preview leveled images under _leveled_preview/

4. Prompt for approval

   • Yes → originals replaced by leveled versions
   • No → preview removed, originals kept

5. Generate missing thumbnails

⚙️ Environment Variables

Variable	Default	Meaning
THUMB_MAX_SIZE	720	Max width/height of thumbnails
LEVELED_PREVIEW_DIR	_leveled_preview	Directory used for preview leveling
LEVEL_ANALYSIS_SIZE	720	Downscale used during leveling analysis
LEVEL_DEBUG_DIR	(unset)	Optional global debug directory (overridden by --debug-dir)

---

📝 Notes

• Works best for horizon-bearing photos, architecture, landscapes
• Deterministic classical CV — great for reproducible pipelines
• Safe to rerun; naming conventions prevent double-processing
• Designed for large photo collections and batch workflows
