Evaluation of different 3D painting algorithms (2008)
Menzel, Jan Robert
In this thesis an application was developed which can be used to create a texture on a 3D model. The whole painting is done in 3D. Different ways of painting in 3D were evaluated, for example painting to texture-maps as well as octree textures.
Extraction of Natural Feature Descriptors on Mobile GPUs (2012)
Hofmann, Robert
In this thesis the feasibility of a GPGPU (general-purpose computing on graphics processing units) approach to natural feature description on mobile phone GPUs is assessed. To this end, the SURF descriptor [4] has been implemented with OpenGL ES 2.0/GLSL ES 1.0 and evaluated across different mobile devices. The implementation is multiple times faster than a comparable CPU variant on the same device. The results proof the feasibility of modern mobile graphics accelerators for GPGPU tasks especially for the detection phase in natural feature tracking used in augmented reality applications. Extensive analysis and benchmarking of this approach in comparison to state of the art methods have been undertaken. Insights into the modifications necessary to adapt and modify the SURF algorithm to the limitations of a mobile GPU are presented. Further, an outlook for a GPGPU-based tracking pipeline on a mobile device is provided.
