Robust Image Topological Feature Extraction
Topological image features such as ridge and valley lines provide an intuitive and powerful way of characterizing image content. The notion of ridges and valleys in digital images was introduced by Haralick already in 1983, but so far it has received fairly limited attention. The main reason is the lack of efficient and robust algorithms for their computation in discrete images. Typically lines...
متن کاملEccentricity based Topological Feature Extraction
The eccentricity transform associates to each point of a shape the geodesic distance to the points farthest away. This can be used to decompose shapes into parts based on the connectivity of the isoheight lines. The adjacency graph of the obtained decomposition is similar to a Reeb graph and characterizes the topology of the object. Graph pyramids are used to efficiently compute the decompositi...
متن کاملFacial Feature Tracking, Extraction and Selection
In this report, first we explain how we moved toward implementing an algorithm for tracking facial features. The explanations, thoroughly covers our experiences, both our failures and successful trials. As a failed experienced of facial feature tracking, we have explained the correlation-based tracking and its improved extension. The second tracking method, is devoted to Active Appearance Model...
متن کاملLarge Scale Feature Extraction and Tracking
OF THE THESIS Large Scale Feature Extraction and Tracking by Pinakin Dhume Thesis Director: Professor Deborah Silver The goal of Scientific Visualization is to provide a more intuitive interpretation of the data being presented. Traditionally, visualization of 3D time-varying datasets is done using animation based on either iso-surfacing or volume rendering. However, for datasets with continuou...
متن کاملTopological Extraction and Tracking of Defects in Crystal Structures
Interfaces between materials with different mechanical properties play an important role in technical applications. Nowadays molecular dynamic simulations are used to observe the behavior of such compound materials at the atomic level. Due to different atom crystal sizes, dislocations in the atom crystal structure occur once external forces are applied, and it has been observed that studying th...
