1. On Enhancement and Quality Assessment of Audio and Video in Communication Systems
Sammanfattning : The use of audio and video communication has increased exponentially over the last decade and has gone from speech over GSM to HD resolution video conference between continents on mobile devices. As the use becomes more widespread the interest in delivering high quality media increases even on devices with limited resources. LÄS MER
2. Very Low Bitrate Video Communication : A Principal Component Analysis Approach
Sammanfattning : A large amount of the information in conversations come from non-verbal cues such as facial expressions and body gesture. These cues are lost when we don't communicate face-to-face. But face-to-face communication doesn't have to happen in person. With video communication we can at least deliver information about the facial mimic and some gestures. LÄS MER
3. Wireless video sensor network and its applications in digital zoo
Sammanfattning : Most computing and communicating devices have been personal computers that were connected to Internet through a fixed network connection. It is believed that future communication devices will not be of this type. Instead the intelligence and communication capability will move into various objects that surround us. LÄS MER
4. Towards accessible content creation of real world objects for virtual environments
Sammanfattning : 3D reconstruction is the general problem of creating 3D models from real world objects. In today's movie and games industry, there is an increasing demand for using real world content as assets in production. LÄS MER
5. Off-line Foveated Compression and Scene Perception: An Eye-Tracking Approach
Sammanfattning : With the continued growth of digital services offering storage and communication of pictorial information, the need to efficiently represent this information has become increasingly important, both from an information theoretic and a perceptual point of view. There has been a recent interest to design systems for efficient representation and compression of image and video data that take the features of the human visual system into account. LÄS MER
