FastAPI OpenCV App - Notebook Ops Integration

Install

• Create/activate a Python env
• Install deps:

pip install -r requirements.txt

Run

From this folder:

uvicorn main:app --reload --host 127.0.0.1 --port 8000

Open http://127.0.0.1:8000, then use "Notebook Operations" in the sidebar.

New endpoints

• GET /notebook_ops/ — form
• POST /notebook_ops/ — process upload with params:
  • operation: convolution | zero_padding | fourier_transform | reduce_periodic_noise
  • kernel_type (for convolution): average | gaussian | sharpen | edge
  • padding_size (for zero_padding): int
  • radius (for reduce_periodic_noise): int

Notes:

• Previously there was a separate 'filter' operation (low/high/band). It was redundant with convolution kernels, so its options were merged into 'convolution' for simplicity.

Results are saved to static/uploads and rendered in templates/result.html.
