Will This Selfie Make a Good Malfoid AI Portrait? A Pre-Upload Photo Checker in Python (Face Count, Size, Sharpness, Exposure)

说明与用途

Python脚本检查自拍是否符合Malfoidai.com的照片要求（尺寸、格式、单人正面、光照、锐度、邮票测试），以避免糟糕的肖像和退款。

问题

Clients need to ensure a selfie meets strict photo requirements before paying for a Malfoid AI portrait, otherwise the portrait may be poor or refunded.

结果

The checker validates all studio requirements in under a second, preventing costly portrait failures and refunds.

工作流

• 1. Create a virtual environment and install dependencies: python3 -m venv .venv && . .venv/bin/activate && pip install "opencv-python-headless<5" pillow numpy
• 2. Run the checker: python3 selfie_check.py my_selfie.jpg
• 3. The script reports OK or FAIL for each rule (file size, format, face count, face size, sharpness, exposure, stamp test).
• 4. If any check fails, correct the photo (e.g., retake, adjust lighting, crop) and re-run.
• 5. Once all checks pass, upload the photo to Malfoidai.com for portrait generation.

证据

The studio's own photo guide puts it as "one clear, front-facing photo of one adult with the whole face visible, in even light and without a heavy filter. JPEG, PNG or WebP up to 10 MB."

The script below is mine and runs locally. It doesn't upload anything.

Pin OpenCV below 5. In the 5.0 wheel I tried, cv2.CascadeClassifier is gone from the main module, and the script fails at import.
