A method is proposed to enhance vascular structures within the framework of scale space theory. We combine a smooth vessel filter which is based on a geometrical analysis of the Hessian's eigensystem, with a non-linear anisotropic diffusion scheme. The amount and orientation of diffusion depend on the local vessel likeliness. Vessel enhancing diffusion (VED) is applied to patient and phantom da...

UNLABELLED PREMISE OF THE STUDY Vessels are the chief conduit for long-distance water transport in the majority of flowering plants. Vessel length is a key trait that determines plant hydraulic efficiency and safety, yet relatively little is known about this xylem feature. • METHODS We used previously published studies to generate a new global data set of vessel length in woody plants. The...

The separation of the retinal vessel network into distinct arterial and venous vessel trees is of high interest. We propose an automated method for identification and separation of retinal vessel trees in a retinal color image by converting a vessel segmentation image into a vessel segment map and identifying the individual vessel trees by graph search. Orientation, width, and intensity of each...

Abstract Marine debris pollution has become an important issue in recent years. It impact on marine environment and life, as well effecting human health. The objective of this study was to identify the composition waste that produced from fishermen’s activities. research conducted Cikidang Fishing Port, Pangandaran. data types fishing vessel were grouped based vessel’s dimension. result show pl...
