Impact of Contouring Accuracy on Expected Tumor Control Probability for Head and Neck Cancer: Semiautomated Segmentation Versus Manual Contouring

Autocontouring versus manual contouring.

Salient object segmentation based on active contouring

Traditional saliency detection algorithms lack object semantic character, and the segmentation algorithms cannot highlight the saliency of the segmentation regions. In order to compensate for the defects of these two algorithms, the salient object segmentation model, which is a novel combination of two algorithms, is established in this paper. With the help of a priori knowledge of image bounda...

the comparative impact of prompts and recasts in processing instruction versus meaningful output-based instruction on efl learners’ writing accuracy

the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...

Use of fibrin sealant in neck contouring.

BACKGROUND The "suture suspension" platysmaplasty technique has been shown to be an effective and reliable procedure over the last decade. OBJECTIVE We investigated the effectiveness of fibrin sealant in reducing the recovery time after suture suspension platysmaplasty. METHODS After contouring the neck with our standard suture sling, hemostasis was assured. The instruments and gloves were ...

Contouring Controller for Precise Motion Control Systems

This paper discusses the trajectory generation algorithm, contour error construction method and finally the contour controller design. In the trajectory generation algorithm combination of elliptical Fourier descriptors (EFD) and time based spline approximation (TBSA) is used to generate position, velocity and acceleration references. Contour error is constructed using transformation of traject...
