Understanding and Implementing Cancellable Templates in Biometrics for privacy protection
Implemented minutiae extraction from the finger print image.
Steps involved
Transform input image to black and white image.
Image thinning - Convert input image to thin image.
Detecting the bifurcations and ridges.
Bifurcation Points
Minutiae Points
Converting coordinates to csv for processing
Get the respective (x,y) coordinates for the corresponding ridges and bifurcation points (minutiae) and store it in a csv / array.
Coordinates of minutiae points are stored in an 1-D array and the corresponding line graph is plotted to visualize the points.
