Thanx for providing the program
i do get errors on 2 variable "START" and "FINISH" and since I am a beginner regarding Matlab i couldn't find a way to solve it and so my questoin here is whether should i use the file name of the image at the places of hose 2 variables or else what else should I do?
My actual question here what to do with using the 2 variables "START" and "FINISH"?
After the minutiae extraction process we get a N rows X 6 column Feature Matrix. .
The First 2 columns represent the (x,y) co-ordinates of the Nth minutiae..
The fourth Column represents the orientation is guess.. ( am i right?)
What do the 3rd , 5th & 6th columns represent.. ?? can anybody tell mee..
Btw "@ Joshua" sir, very nice effort to share the code so that we could learn from it..
One question about the translation vector (regParams.t):
I have the following 3 points before rotation:
A1 = (400, 400, 200,)
A2 = (600, 600, 200,)
A3 = (2000, 2000, 2000)
and after rotation:
B1 = (400, 400, 200,)
B2 = (600, 600, 200,)
B3 = (2000, 2000, 2001)
so all point are the same, just B3z is 2001 instead of 2000. Then the computed translation vector using your code is: (162, -76,4001)
What doesn't make sense to me? Because just one single point changed it's z-value from 2000 to 2001 what is just a difference of 1...?
Nevertheless, the result seems to be right, because:
b(:,1) = regParams.R * a(:,1) + regParams.t
