1. Model-based head tracking and coding
Sammanfattning : This thesis treats two topics in model-based coding; coding of facial textures (Part 1) and real-time head tracking (Part 2).In Part 1, it is shown that a face image can be efficiently coded using a parameterization based on geometrical normalization followed by Karhunen-Loeve transformation (KLT).

2. Expressing emotions through vibration for perception and control
Sammanfattning : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. LÄS MER
3. Semi-Automating Forestry Machines : Motion Planning, System Integration, and Human-Machine Interaction
Sammanfattning : The process of forest harvesting is highly mechanized in most industrialized countries, with felling and processing of trees performed by technologically advanced forestry machines. However, the maneuvering of the vehicles through the forest as well as the control of the on-board hydraulic boom crane is currently performed through continuous manual operation. LÄS MER
4. Bring Your Body into Action : Body Gesture Detection, Tracking, and Analysis for Natural Interaction
Sammanfattning : Due to the large influx of computers in our daily lives, human-computer interaction has become crucially important. For a long time, focusing on what users need has been critical for designing interaction methods. LÄS MER
5. Model Based Coding : Initialization, Parameter Extraction and Evaluation
Sammanfattning : This thesis covers topics relevant to model-based coding. Model-based coding is a promising very low bit rate video coding technique. The idea behind this technique is to parameterize a talking head and to extract and transmit the parameters describing facial movements. At the receiver, the parameters are used to reconstruct the talking head. LÄS MER
