List of image processing algorithms:already implemented and offered by GIL and those not yet implemented but of interest of GIL users and developers. The list is open to all image processing algorithms, from basic and classic through to complex and modern, from old and sub-optimal through specialised, optimal or parallel-friendly.
Please, feel free to add name of your favourite algorithm to the wish list and if possible, also title/link to paper or description of the algorithm and any materials that useful for developers interested in implementing it, marking with:
- ✔️ algorithms implemented by GIL with corresponding pull request number in the PR column
- ❌ algorithms not yet implemented or accepted to GIL
