To ensure consistency across the tile processing pipeline, a dedicated Python environment is required. : 3.9+ recommended. Key Libraries : OpenCV , NumPy , and SQLite3 .

| Step | Action | Tool | Tips | |------|--------|------|------| | 8.1 | Create a “tile‑grid” database | Python (SQLite) + OpenCV | Store avg‑lab, histograms, image path | | 8.2 | Downsample master to grid resolution | Photoshop “Image Size” or custom script | Use bicubic smoother for minimal aliasing | | 8.3 | For each grid cell, find best‑matching tile | Custom Python (scipy KD‑Tree) | Use CIEDE2000 distance for perceptual fidelity | | 8.4 | Assemble the mosaic canvas | Pillow (Python) or Photoshop “Place Embedded” batch | Keep a 1‑pixel “gap” if you want a “bordered” look | | 8.5 | Post‑process global adjustments | Lightroom / Photoshop “Curves”, “Color Balance” | Apply a subtle vignette to hide mismatched edges | pppe153 mosaic015838 min high quality

Before generating the final mosaic, verify that the dataset is complete and the index database is synchronized with the local filesystem. : Use sqlite3 to query the tiles_index.db . Integrity Script : To ensure consistency across the tile processing pipeline,
