General Information

Lecturer: Mohan S Kankanhalli

Lectures: 26 Hours (Thursdays, 6.30pm - 8.30pm, SR3 (COM1 02-12))

Midterm Examination: 9th October, 5.00pm

Aims and Objectives:

This course aims to develop a critical appreciation of the theoretical background as well as the practical issues of multimedia systems.

Brief Description:

This course lays the foundation for graduate students to do research in multimedia: images, videos, speech, graphics and documents. The module covers the main topics common to various multimedia applications, i.e., multimedia representation, processing, and analysis. By teaching the topics together with the computational tools commonly used in multimedia research, it aims to strike a balance between theoretical considerations and practical applications. Upon completion, the students should be able to understand the theoretical foundation of multimedia processing and analysis, and apply computational tools such as Matlab to the processing and analysis of multimedia data.

Grading information:

Midterm Exam: 15% [open book]
Three Assignments: 45%
Project: 40%
