Description

🚀 Feature Description

Since most of the image processing work is done primarily in u8, having highly optimized functions that support u8, preferably using SIMD, seems like a great functionality to have, especially for the upcoming orb detector, etc

There's already issues open for specific functions, but this issue is to try to figure out what to do with the library in general

📂 Feature Category

Image Processing

💡 Motivation

efficient image processing

💭 Proposed Solution

this is the thing we could discuss here, what functions to refactor for u8 and how to go about it

📚 Library Reference

preferably based on openCV's implementations of these functions

🤝 Contribution Intent

  • I plan to submit a PR to implement this feature
  • I'm requesting this feature but not planning to implement it

Contributor guide

Research direction
Review existing image processing functions in kornia rs, identify which ones would benefit from u8 support, and study OpenCV's u8 implementations to plan appropriate SIMD optimized versions.
