Recent studies show that 3D visualization and browsing interfaces in content-based exploration systems of unstructured data represent a promising alternative to classical 2D grids. In this paper, we study 3D visualization techniques based on the particle physics model with focus on efficient evaluation of presentation layouts. We show that the particle physics model is a versatile approach suitable...
Preserving continuity between individual exploration steps in a process of multimedia exploration is a concept of natural intuition that sometimes decides if a particular exploration system is usable or not. One of ways how to emulate the continuity of the exploration process is adding some sort of granularity into this process. Then anyone who uses such system can explore particular areas in less...
In this paper, we compare eight different multimedia exploration methods. We describe each of them individually and evaluate their effectiveness in a user study focusing on different aspects of image exploration needs. We also created a testing scenario for the user study and defined several metrics to compare the exploration methods.
After two decades of research, the techniques for efficient similarity search in metric spaces have combined virtually all the available tricks resulting in many structural index designs. As the representative state-of-the-art metric access methods (also called metric indexes) that vary in the usage of filtering rules and in structural designs, we could mention the M-tree, the M-Index and the List...
In this paper, we investigate the content-based multimedia exploration techniques benefiting from the metric space indexing approach. We present two orthogonal approaches for browsing multimedia collections and discuss their strong and weak points. We also provide an implementation of the two approaches in our publicly available demo application where users can try to find as much objects of a predefined...
