Recovering the three-dimensional (3D) object shape lies as an unresolved and active research topic on the cross-section of computer vision, photogrammetry and bioinformatics. Although various techniques have been developed to tackle the shape recovery problems, the computational complexity and the constraints introduced by the other algorithms have limited(More)
Thousands of scientists strive to identify cellular mechanisms that could lead to breakthroughs in developing ameliorative treatments for debilitating neural and muscular conditions such as spinal cord injury (SCI). Most studies use rodent models to test hypotheses, and these are all limited by the methods available to evaluate animal motor function. This(More)
Recovering the three-dimensional (3D) object shape remains an unresolved area of research on the cross-section of computer vision, photogrammetry and bioinformatics. Although various techniques have been developed, the computational complexity and the constraints introduced to overcome the problems have limited their applicability in the real world(More)
— Locomotion is commonly used as a method for evaluating the effectiveness of interventions and treatments for recovery of function after spinal cord injury in rodent models. However, most conventional approaches to assess recovery rely on a series of semi-quantitative visual inspections. In the present study, we propose a volume intersection approach to(More)
—This paper discusses a novel approach for image-based three-dimensional (3D) object shape recovery. Let there be a set of hypothetical planes in the object space created by rotating a reference plane about an arbitrary axis. These planes slice the objects and create cross-sections at which the object shapes become the outlines on the plane, which we will(More)
Interest points on the building façade are the basic element for 3-D building modeling and texturing. Grouping these points to the same or separate buildings is a fundamental process for establishing building models and detecting building boundaries. The grouping process is generally achieved by analyzing the geometric relation and the distances between the(More)
