Searching for Similar 3D Models
Karásek, Miroslav ; Najman, Pavel (referee) ; Španěl, Michal (advisor)
The work deals with the design and implementation of similarity based search in database of 3D models. The database is realised using of quick Python data structures. For Spherical harmonics and 3D Zernike deskriptors extraction are used third-party libraries. REST application interface is designed to access the search engine. A web based application was designed as an example of the REST application interface usage. Furthermore, the work deals with the search quality, presents results of the implemented database and suggests possible improvements.

Searching for Similar 3D Models
Šťáva, Zdeněk ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This paper deals with searching similar 3D models in a database containing up to thousands of models. It focuses in particular on the comparison of existing descriptors used to describe 3D models and the subsequent evaluation of similarity between models. In particular, the descriptors Rotation Invariant Spherical Harmonics and 3D Zernike Descriptor are compared. It also describes the use of libraries to extract these descriptors and to design of various experiments with these libraries over several object databases. It examines the effect of scale, translation, deformation and rotation of different 3D models on the resulting descriptor and the overall accuracy of both selected methods. These results compare.
