During my university years, I've done a lot of image processing work using Matlab. I would point out an SVM classifier used to detect ulcers on images of patients extremities. Another one would be my masters' thesis (Person identification using computer vision), which I started off using Matlab and finished with C++.
Also, I've used Matlab to write an ECG signal analyser to distinguish notable parts of the signal (P,Q,R,S,T intervals) from a dataset heavily affected by high frequency noise and low frequency drift. Since I am new to this community, I am willing to work for less for a good review.
