What are some good alternatives to OpenCV for computer vision?

I’m just curious—what's the deal with OpenCV? Is there something specific that you're finding problematic?

Honestly, there aren’t any real alternatives that match OpenCV's capabilities. Sure, there are libraries that cover a few computer vision algorithms, but nothing compares to the power of OpenCV. I'm curious why you're looking for alternatives since OpenCV is open-source and has a pretty liberal license.

You might find some interesting alternatives like scikit-image, which is great for image processing, and it's built on NumPy and SciPy. ImageJ/Fiji is another one that’s popular for scientific imaging, especially in biology. Then there's SimpleITK for medical imaging, Mahotas for speed in edge detection, and Pillow for basic image manipulation. Each one has its own strengths, so the best choice really depends on what you need!
