Topological Active Volumes

چکیده
The topological active volumes (TAVs) model is a general model for 3D image segmentation. It is based on deformable models and integrates features of region-based and boundary-based segmentation techniques. Besides segmentation, it can also be used for surface reconstruction and topological analysis of the inside of detected objects. The TAV structure is flexible and allows topological changes in order to improve the adjustment to object’s local characteristics, find several objects in the scene, and identify and delimit holes in detected structures. This paper describes the main features of the TAV model and shows its ability to segment volumes in an automated manner.

Handling Topological Changes in the Topological Active Volumes Model
The Topological Active Volumes (TAV) model is a 3D deformable model based on the active nets and used for segmentation and reconstruction tasks. The model implements automatic procedures, the so called topological changes, that alter the mesh structure in order to segment complex surfaces, such as pronounced curvatures or holes, and detect several objects in the scene. This work analyses previo...

متن کاملDFT Studies and Topological Analyses of Electron Density on Acetophenone and Propiophenone Thiosemicarbazone Derivatives as Covalent Inhibitors of Falcipain-2, a Major Plasmodium Falciparum Cysteine Protease
Thiosemicarbazones (TSCs) possess significant antimalarial properties believed to be linked to the inhibition of major cysteine proteases, such as falcipain-2, in Plasmodium falciparum. However, the binding modes of TSCs to the active site of these enzymes are not clear. As a result of this, the nature of the bonding interactions between the active site of falcipain-2 and different derivatives ...
متن کاملApplication of Graph Theory: Relationship of Topological Indices with the Partition Coefficient (logP) of the Monocarboxylic Acids
It is well known that the chemical behavior of a compound is dependent upon the structure of itsmolecules. Quantitative structure – activity relationship (QSAR) studies and quantitative structure –property relationship (QSPR) studies are active areas of chemical research that focus on the nature ofthis dependency. Topological indices are the numerical value associated with chemical constitution...
متن کاملGenerating and Exploring a Collection of Topological Landscapes for Visualization of Scalar-Valued Functions
Any treemap algorithm can be used to translate into a configuration, guaranteeing that the areas of the topological components of the configuration exactly match the (scaled) volumes of their high-dimensional counterparts. Function values between adjacent contours are interpolated using a standard Gaussian-weighted Laplacian. Exploring the Space of Visualizations By using the (scaled) volumes o...
