How to convert MATLAB binary feature matrix to decimal?

2 visualizzazioni (ultimi 30 giorni)
I have binary feature matrices from BRISK, FREAK and ORB descriptors with 512 number of bits.
I tried to use:
d = bi2de(featuresBRISK.Features(:,1),512);
But they are just converted to uint8. How can I convert them to decimal for image classification problem?

When I use the BRISK features, currently, it is in a matix form of uint8. I am going to use it for a classifcation problem.

You can bitget() to extract bits from uint8 if you need to. Or use
bitstream = reshape((dec2bin(A,8) - '0').', 1, [])

If you want/need d to be double instead of uint8, for other purposes like feature analysis, do this:
d = double(d);
