About The Project

I wanted to implement the akaze feature extraction on android using opencv for which I couldn't find any good example online. This one I made using Opencv and with help from some blogs as mentioned in Acknowledgements. For now the app has following features:

• Live feed from camera using opencv
• Feature detection on each frame
• Visualising the keypoints in each frame.
• Double tap to select keyframe and start matching.
• Visualising the keypoints:
  • Green color shows the matched points,
  • Blue color shows the current frame keypoints.

Getting Started

Prerequisites

You need to install:

• Latest opencv version. here I have used opencv 4.5.0. Please make sure its latest opencv that you have.
