How to matching different numbers of features?

1 view (last 30 days)
I'm working on a fingerprint matching program. The extracted features are minutiae, each of these features contains the location (x , y) and angle of direction (o). The number of features extracted from images varies, where the features matrix not the same numbers of rows.
How can I match different numbers of features?
If I use the Euclidean distance, the matrix of features must be equal in dimensions, also If I want to train neural network, the matrix of features must be equal in dimensions.
