Dynamic Programming Based Segmentation in Biomedical Imaging
Many applications in biomedical imaging have a demand on automatic detection of lines, contours, or boundaries of bones, organs, vessels, and cells. Aim is to support expert decisions in interactive applications or to include it as part of a processing pipeline for automatic image analysis. Biomedical images often suffer from noisy data and fuzzy edges. Therefore, there is a need for robust met...
متن کاملSpline-based framework for interactive segmentation in biomedical imaging
Active contours constitute a computationally attractive framework for image segmentation. In this paper, we describe a fully parametric design hat relies on B-spline bases and is specified by control points on the image. Our technique yields successful segmentation results even for hallenging datasets where object contours are not well-defined. We can achieve this because our parametric approac...
متن کاملSegmentation of Magnetic Resonance Brain Imaging Based on Graph Theory
Introduction: Segmentation of brain images especially from magnetic resonance imaging (MRI) is an essential requirement in medical imaging since the tissues, edges, and boundaries between them are ambiguous and difficult to detect, due to the proximity of the brightness levels of the images. Material and Methods: In this paper, the graph-base...
متن کاملTrajectory Segmentation Using Dynamic Programming
We consider the segmentation of a trajectory into piecewise polynomial parts, or possibly other forms. Segmentation is typically formulated as an optimization problem which trades off model fitting error versus the cost of introducing new segments. Heuristics such as split-and-merge are used to find the best segmentation. We show that for ordered data (eg., single curves or trajectories) the gl...
متن کاملSegmentation-Based Lyrics-Audio Alignment using Dynamic Programming
In this paper, we present a system for automatic alignment of textual lyrics with musical audio. Given an input audio signal, structural segmentation is first performed and similar segments are assigned a label by computing the distance between the segment pairs. Using the results of segmentation and hand-labeled paragraphs in lyrics as a pair of input strings, we apply a dynamic programming (D...
