Course Instructor: Costin Boiangiu

Syllabus:

This course introduces students to three main domains: information theory, multimedia standards and multimedia communication.

The first parts refers to statistical (Shannon-Fano, Huffman, Arithmetical), dictionary (LZ77, LZ78, LZW, Deflate) and context compression (PPM, MTF, Burrows-Wheeler) used for lossless data compression; JPEG-Lossless, JBIG, JBIG2, Fax-Group, MRC for lossless image compression; FLAC, Apple Lossless, MPEG-4 ALS, Monkey's Audio, TTA for audio lossless compression; compression in DCT domain (JPEG, MPEG), wavelet domain (JPEG-2000) and fractal compression for images and video lossy compression and MDCT (MP3, WMA) for lossy audio compression.

The last part refers to post-processing for removing compression artifacts (denoising, deringing, deblocking), analyzing media for recovering representative characteristics, and storing on distributed systems, indexing, searching and transmission.

The course has three main teaching methods: presentation of the theory, held by the teacher; presentations based on cutting-edge research articles sustained by the students; and a project developed by the students, starting from proposed ideas, in-progress projects, or a new idea which students can propose.
