Hi opencv community??
I made Fast Rotational Rect and Donut ROI also contour based blob detection
(Not just rotation image and crop, it provide pixel locations sequentially)
You can also adjust pixel gap each row and column
I want to contribute these codes to opencv. How can I do that?
Source code and library link : http://github.com/gellston/FastROI
Other libraries used : simd, eigen3
|fast::fastRect (500x500 roi size)
|fast::fastRect (1000x1000 roi size)
|fast::fastRect (2000x2000 roi size)
|fast::fastDonut (800 radius)
|fast::fastDonut (1500 radius)
|fast::fastBlob (video 1920x1080)
||15~20ms elapse time
|fast::fastBlob(blobFill) (video 1920x1080)
Demo (Very fast blob detection):
Glad to know you are willing to contribute with this work.
OpenCV works different, you don’t add your algorithm to OpenCV, you can offer your help, there is a big TODO list for developers who want to contribute with some coding and testing.
opencv_contrib could be a start.
I don’t know how that works. perhaps open an issue first, show the code and what it does. then likely you will receive guidance on expected documentation, file structure, coding style, expected APIs, maybe test cases, how to get automatically generated python bindings, …
i took a closer look, but had a hard time to compile it, using mingw.
- it needs c++17 support, is that absolutely nessecary ?
- make it as portable as possible (must run on linux/g++, apple/clang, android, etc)
- do you really need Eigen for a simple 2d transform ?
- what happens if there is no SIMD support ?
- do you have any links / papers explaining the algorithms used ?
