Hi ,

I am using AKAZE for feature extraction, and it is very slow compared to other feature extractors such as FAST. Any way to make it faster.

Have you tried downscaling or compressing image before finding feature points. It is usually better to do image processing on a server, then access the services from android.

I have not down scaled the image,but i am just extracting descriptors and sending it to the server and there the matching happens.

I personally prefer 512 x (previous height/previous width)*512 downsizing to extract descriptors. Reason being that modern phones have really good camera and algorithm ll slow down operating on such high quality image
