ECE 417: Multimedia Signal Processing
ECE 417: Multimedia Signal Processing
ECE 417 Multimedia Signal Processing. Characteristics of speech and image signals; important analysis and
synthesis tools for multimedia signal processing including subspace
methods, Bayesian networks, hidden Markov models, and factor graphs;
applications to biometrics (person identification), human-computer
interaction (face and gesture recognition and synthesis), and
audio-visual databases (indexing and retrieval). Emphasis on a set of
python machine problems providing hands-on experience. 4 undergraduate
hours. 4 graduate hours. Prerequisite: ECE 310 and ECE 313.
