The DMET Department conducts research in areas such as Speech and Audio Signal Processing, Digital Image and Video Processing, and Computer Graphics & Vision. Speech processing refers to analysis, synthesis and recognition of speech signals. It is playing a key role in the state-of-art digital speech communication and multimedia services. While Internet and wireless telephony is expected to remain one of the most important application for several years to come, the use of speech processing applications, such as Automatic Speech Recognition (ASR), Text-to-Speech Synthesis (TTS), speaker identification/verification, emotion and mood analysis, is expected to increase in multimedia-rich scenarios. Digital image and video processing has become an important enabling technology for many applications including digital multimedia services over the wired and wireless Internet, digital surveillance, smart homes/vehicles/environments, digital cinema, HDTV and HD-DVD. Computer graphics is mainly concerned with creation, processing and rendering of 3D digital scene representations and object models. These representations can be purely computer-generated or a combination of graphical models and real world images and videos registered together using 3D computer vision. Vision technologies can create replica of real world, not only the geometry and appearance of objects and surfaces but also their motion and behavior.

This department is composed of 3 research groups, namely:
