## Core Language & Environment
|
|
- **Python**: Primary language for all scripts (v3.10+ expected).
|
|
|
|
## Principal Libraries
|
|
- **OpenCV (`cv2`)**: Core computer vision operations, image thresholding, morphological operations, pattern matching (Template Matching), Difference Hash (`_dhash`), Laplacian variance.
|
|
- **NumPy (`np`)**: Matrix operations and mask manipulations for image arrays.
|
|
- **EasyOCR (`easyocr`)**: Convolutional/Recurrent Neural Network based OCR for detecting measure numbers to prevent duplications.
|
|
|
|
## Utilities
|
|
- **yt-dlp**: Command-line tool called via `subprocess` for downloading high-quality video frames (720p preferred over 1080p to optimize processing) from YouTube.
|
|
- **img2pdf**: Lightweight library to convert combined tab images into A4 PDF output.
|
|
- **Pillow (`PIL`)**: Additional image manipulation where OpenCV is less ergonomic.
|
|
|
|
## Execution Requirements
|
|
- Windows OS (noted via `sys.platform == "win32"` encodings).
