Digital Processing Option

Digital Processing is…

If you want to improve contrast in an image, MPEG a movie, filter a sound…

If you want to teach a computer to see, recognize a voice, talk to you…

If you want to simulate a system, create a game…

Digital Processing focuses on.. Building tools for multimedia, gaming, and

scientific communities Tools such as compression and decompression

of images (JPEG, Wavelets, etc.), movies (H.261, MPEG, etc.), sounds (MP3 etc.)

Tools such as image modification (contrast, sharpening, effects), image identification (object capturing, template matching, face recognition systems, etc. used in medical fields, robotic assisted factories, etc.)

Tools such as audio filters, sound segmenting, music stretching

Programming Languages

C is used primarily for working with the Win32 API

C++ is used in Comp4995 with DirectX for gaming as this was desired by the gaming industry

Java was used this year for Android development on Nexus7 devices (morpher, MPEG compression, image stitching)

C# was combined with C and Win32 to develop the sound editor in Comp3931

Who should take this option?

Interested in graphics, audio, and image processing, gaming systems, multimedia authoring systems, scientific endeavors

Good mathematical aptitude especially in Algebra and Trigonometry

Like to code a LOT!

Assignments and Projects

Audio editor (cut/copy/paste, filtering, etc.)

Morpher Face recognition OCR (optical character recognition) Motion Capture Fingerprint recognition Speech recognition Image compression (JPEG) and video

compression (MPEG) Game Development

Projects courses (Comp3900/4900)

Past projects include a motion capture system*, Signal Analysis for General Hydrogen Corp. (spin off from Ballard Fuel Cell system)*, sound recognition system, fingerprint analyzer, etc.

This year the IUGO game company has offered to be a client for mentoring purposes (students develop their own game) and observing students capabilities for possible employment and reference from the gaming industry.
