Active geometric model : multi-compartment model-based segmentation & registration
… novel, variational and statistical approach for model-based segmentation. Our model generalizes the Chan-Vese model, proposed for concurrent segmentation of multiple objects embedded in the same image domain. We also propose a novel shape descriptor, namely the Multi-Compartment Distance …

Development of a statistical shape and appearance model of the skull from a South African population
Statistical shape models (SSMs) and statistical appearance models (SAMs) have been applied in medical analysis such as in surgical planning, finite element analysis, model-based segmentation, and in the fields of anthropometry and forensics. Similar applications can make use of SSMs and SAMs of the …

Toward Trustworthy Power Line Perception from Aerial Imagery: Segmentation and Reliability Monitoring
… A key component of these systems is power line segmentation, which supports downstream tasks such as clearance analysis, vegetation monitoring, damage assessment, and navigation. However, power lines are difficult to segment in aerial imagery because they are narrow, low-contrast, and often …

Integrating contour-coupling with spatio-temporal models in multi-dimensional cardiac image segmentation
… to inter/intra observer variability. Automatic segmentation algorithms are a promising solution to alleviate this issue. Within the model-based segmentation domain, a popular strategy considers the entire segmentation target as a single entity. Although intuitive, this modus operandi suffers …

Robust recovery of piled box-like objects in range images
… determined. Our strategy for object recovery is model based, uses geometric parametric entities for object modeling, and has two aspects, in both of which, in addition to the input range image a boundary image obtained by the former by means of edge detection is employed. Firstly, globally …

Object detection and activity recognition in digital image and video libraries
This thesis is a comprehensive study of object-based image and video retrieval, specifically for car and human detection and activity recognition purposes. The thesis focuses on the problem of connecting low level features to high level semantics by developing relational object and activity …
