LiveCapture

LiveCapture 📸

LiveCapture is a tool to experiment with computer vision, in particular with image processing. The workflow is quite simple.

  1. You write a processing function, which takes a logger and an image.
  2. You run the script including the processing function.
  3. From a live view of the camera, you capture a frame using the Esc key.
  4. The capture is then run through your processing functions. The results are logged in log.html using visual-logging.
