fingerprint
program for fingerprint recognition using minutia
The general shape of the fingerprint is generally used to pre-process the
images, and reduce the search in large s. This uses the general
directions of the lines of the fingerprint, and the presence of the core
and the delta. Several categories have been defined in the Henry system:
whorl, right loop, left loop, arch, and tented arch.
Most algorithms are using minutiae, the specific points like ridges
ending, bifurcation... Only the position and direction of these features
are stored in the signature for further comparison.

denoisingWavelet
Wavelet denoising
For using this code need to use signal toolbox and general toolbox in your matlab
In the first part of this assignment, we asked to obtain a (black-and-white) digital image of size
512 by 512 and then generate noisy image by adding a Gaussian noise but under the condition of
having SNR=20dB by select the suitable value of variance for Gaussian noise formula.
Second step is performing wavelet denoising using the hard thresholding (Use the db 6 for four
levels) in the condition of finding the optimal thresholding value of T in terms of the SNR obtained. It
means that, we should find the highest SNR value by finding the suitable value for threshold. Then we
asked to do the same process but this time using soft thresholding.
Finally for the last part of question one, we should compare the results of the obtained SNR
with the recommendations of 3*sigma for the hard thresholding and 3/2*sigma for the soft
thresholding.
