5 Ultimate Python Libraries for Image Processing
Pillow is an image processing library for Python derived from the PIL or the Python Imaging Library. Although it is not as powerful and fast as openCV it can be used for simple image manipulation works like cropping, resizing, rotating and greyscaling the image. Another benefit is that it can be used without NumPy and Matplotlib.

  • Modern Image Processing Algorithms Implementation in C
    It looks promising. I like the way each algorithm is explained with minimal example and demo images. I'm looking for such a lightweight vision lib to embed simple image manipulation programs on tiny ESP32-CAM boards. OpenCV seems too heavy to integrate on such small devices. So far, I've been able to develop simple image processing programs with CImg[1] (simple filtering, image cropping, adding text). I'll try to... - Source: Hacker News / almost 2 years ago
