Image compression: Fourier vs Wavelets

Maurice Samulski

WaveletsDigital images have become an important source of information in the modern world of communication systems. Thinks about FBI fingerprints, MRI scans, ECG data, digital camera photos, building plans etc. In their raw form, these images require an enormous amount of memory. With the introduction of multimedia computing, the demand for processing, storing and transmitting images has increased exponentially. In the last two decades a considerable amount of research has been devoted to tackle the problem of image compression.

During the Research Lab 4 course, I wrote a paper about the similarities and differences, advantages and disadvantages of the two well known compression techniques: Fourier and Wavelets. JPEG, JPEG2000, DiVX and MPEG, all of them are based on one of these two techniques.

HypercomputationCurrently, hypercomputation is still very theoretical and there is still enough to discuss. Hypercomputation concerns the study of computation beyond that defined by the Turing machine. It is a multi-disciplinary research area across a wide variety of fields, including computer science, philosophy, physics, electronics, biology and artifical intelligence.

For a seminar to be given at the university, I’ve written with two fellow students a paper about the pre-hypercomputation history, explanation of hypercomputation and the philosphy of hypercomputation and artificial intelligence.

Observational Research on TVs

Maurice Samulski

Observational research

During a marketing high tech products class I participated in a group project and did some observational research on self promoting television sets for Philips Consumer Electronics. Our goal was to deliver ideas to Philips Consumer Electronics for the promotion of televisions in television shops by observing people who are buying a new TV set.
