We propose a novel anatomical labeling algorithm for bronchial branches extracted from CT images. This method utilizes multiple branching models for anatomical labeling. In the actual labeling process, the method selects the best candidate models at each branching point. Also a special labeling procedure is proposed for the right upper lobe. As an application of the automated nomenclature of br...

The use of integrated models of the human body in three-dimensional environments enables the study of the anatomic structures with a high degree of interactivity and detail. The geographical information systems approach in building topological models allows overcoming certain limitations found in anatomical atlases. In this study, an integrated (vector-raster) 3D model, which defines the extern...

In this paper we introduce the concept of statistical deformation models (SDM) which allow the construction of average models of the anatomy and their variability. SDMs are built by performing a statistical analysis of the deformations required to map anatomical features in one subject into the corresponding features of another subject. We demonstrate the applicability of this new framework to ...

The purpose of this study was to identify the anatomic structures of the abdominal region of cat throughcomputed tomography (CT) to be used by veterinary radiologists, clinicians and surgeons. The abdominalregion of four cats were scanned twice, with and without using contrast medium in a same position, usinghigh-resolution imaging protocol. Slice intervals were 11 mm and were adjusted so that ...

The effectiveness of appearance based person models strongly relies on a sufficiently large number of high quality training samples. Generating training data in terms of bounding boxes is already a time consuming task. If more complex person models are used, like part-based models or models suitable for human pose estimation, the labeling process becomes infeasible. In the context of pose estim...

Registration between 3-D images of human anatomies enables cross-subject diagnosis. However, innate differences in the appearance and location of anatomical structures between individuals make accurate registration difficult. We characterize such anatomical variations to achieve accurate registration. We represent anatomical variations in the form of statistical models, and embed these statisti...

The art of wax modelling has an ancient origin but rose to prominence in 14th century Italy with the cult of votive artefacts. With the advent of Neoclassicism this art, now deemed repulsive, continued to survive in a scientific environment, where it flourished in the study of normal and pathological anatomy, obstetrics, zoology and botany. The achievement of having originated the creation of a...

A significant objective of neuroinformatics is the construction of tools to readily access, search, and analyze anatomical imagery. This goal can be subdivided into development of the necessary databases and of the computer vision tools for image analysis. When considering mesoscale images, the latter tools can be further divided into registration algorithms and anatomical models. The models ar...
