Vessel segmentation is one of the challenging tasks in the field of image analysis. This paper gives a comprehensive study for liver vessel segmentation of 3D images. The main goal is to segment the liver vessels in a given 3D DICOM image of the abdomen. We proposed a cascaded liver segmentation structure such that we first extracted the liver region from the abdomen, then vessel enhancement is...

This paper describes a general system which maps from a phonological specification of an utterance’s intonation to a F0 contour. The system can accommodate a variety of feature based phonological description schemes. Speaker dependent characteristics can be modelled and an automatic method of determining these is described.

This paper introduces derivations of soil line influences on two-band vegetation indices (VIs) and vegetation isolines in the red and near infra-red reflectance space. Soil line variations are described as changes in the soil line parameters (slope and offset) and the red reflectance of the soil surface. A general form of a VI model equation written as a ratio of two linear functions (e.g., NDV...

We present a simple, efficient and practical algorithm for constructing and subsequently simplifying contour maps from massive high-resolution DEMs, under some practically realistic assumptions on the DEM and contours.

A stochastic representation of singing styles is proposed. The dynamic property of melodic contour, i.e., fundamental frequency (F0) sequence, is assumed to be the main cue for singing styles because it can characterize such typical ornamentations as vibrato . F0 signal trajectories in the phase plane are used as the basic representation. By fitting Gaussian mixture models to the observed F0 tr...

A modified Sammon algorithm was developed to display a relationship between proteins based on their amino acid composition. In the first stage of the method, a 19-dimensional compositional space of representative proteins was mapped into a 2-dimensional space (2-D) using the original Sammon projection creating a contour map. In the second stage, this contour map was used as a reference for new ...
