Research Areas Sound and Image Processing
The research at the Sound and Image Processing (SIP) Laboratory includes a variety of topics that relate to the application of signal processing and information theory to speech, audio, and video signals and images with the aim to facilitate communication. Examples of research topics that we are active in are auditory modeling, generic source coding (the figure on the right shows a lattice quantizer), audio and speech coding, video coding, speech enhancement, objective methods for speech-quality estimation, robust encoding for packet networks, audio-visual context awareness, etc. An area of special emphasis is technology for hearing impaired people.
Our work is funded by a variety of sources. Industrial sponsors of research projects at the Sound and Image Processing Lab include Ericsson, GN Resound, and Global IP Solutions. Public sponsors of research projects include the European Commission and the Swedish Research Council. The projects of SIP include:
