# fourier-cropper
An application to filter an image in the frequency domain interactively
This project uses [OpenCV 4](https://github.com/opencv/opencv/tree/4.10.0) (see additional packages in https://docs.opencv.org/3.4/d7/d9f/tutorial_linux_install.html)
It is recommended build OpenCV with `-DOPENCV_GENERATE_PKGCONFIG=ON` see [this](https://stackoverflow.com/questions/15320267/package-opencv-was-not-found-in-the-pkg-config-search-path)
_TODO_:
- The idea will be binding all required libraries into a single AppImage, in order to ship the application directly
- Download sample images (directional patterns, noisy, etc.)
- Show the messagebox of on_filterPushButton_released in another thread to let the text and icon appear

**Local (Linux):** install `build-essential`, `qtbase5-dev`, `qttools5-dev-tools`, `pkg-config`, `libopencv-dev`; then `mkdir build && cd build && qmake CONFIG+=release ../fourier-cropper.pro && make -j$(nproc) && ./FourierCropper`.
**Docker:** `docker compose build && docker compose run --rm app` (GUI needs WSLg or X11; use `DISPLAY=:1 docker compose run --rm app` if not `:0`). The compose bind-mounts this repo to `/opt/fourier-cropper`—put images under the project on disk and open them from that path (e.g. `/opt/fourier-cropper/...`) in the file dialog.
