Image Quality Filter
Detect and filter out low-quality images including blurry, dark, too bright, or low resolution images. Use when user wants to clean up image datasets by removing poor quality images.
Features
Usage
# Scan for low quality images
python scripts/quality_filter.py scan /path/to/images/Filter with custom thresholds
python scripts/quality_filter.py scan /path/to/images/ \
--blur-threshold 100 \
--min-resolution 640x480 \
--min-brightness 30 \
--max-brightness 220Delete low quality images
python scripts/quality_filter.py scan /path/to/images/ --action delete
Examples
$ python scripts/quality_filter.py scan ./images/Scanning 150 images...
Analyzing quality...
Found 12 low-quality images:
[BLUR] photo_blurry.jpg (score: 45)
[BLUR] image_low.jpg (score: 62)
[DARK] dark_photo.jpg (score: 38)
[BRIGHT] overexposed.jpg (score: 41)
[RES] tiny_image.png (320x240)
Total: 12 low-quality images removed
Quality Criteria
| Criterion | Threshold | Description | |-----------|-----------|-------------| | Blur | < 100 | Laplacian variance (lower = blurrier) | | Brightness | 30-220 | Out of range is poor | | Resolution | > 640x480 | Below minimum is low quality |
Installation
pip install pillow numpy opencv-python
