Code examples for Google Vision API written in Python.
Example codes has following features:
- Face Detection
- Landmark Detection
- Logo Detection
- Label Detection
- Text Detection
- Safe Search Detection
- Python 3.x
- API Token(Vision API)
Set Google Vision API Token to environment variables.
$ export VISION_API=xxxxx
$ pip install -r requirements.txt
To enable accurate image detection within the Google Cloud Vision API, images should generally be a minimum of 640 x 480 pixels (about 300k pixels). Full details for different types of Vision API Feature requests are shown below:
| Vision API Feature | Recommended Size | Notes |
|---|---|---|
| FACE_DETECTION | 1600 x 1200 | Distance between eyes is most important |
| LANDMARK_DETECTION | 640 x 480 | |
| LOGO_DETECTION | 640 x 480 | |
| LABEL_DETECTION | 640 x 480 | |
| TEXT_DETECTION | 1024 x 768 | OCR requires more resolution to detect characters |
| SAFE_SEARCH_DETECTION | 640 x 480 |
