Image partition and video segmentation using the Mumford - Shah functional
The aim of this Thesis is to present an image partition and video segmentation procedure, based on the minimization of a modified version of Mumford-Shah functional. Generally, in most image processing applications, an image is usually viewed as a set of pixels placed on a rectangular grid. A single pixel provides an extremely local information making impossible any kind of interpretation. The ...
متن کاملVideo Segmentation using 2D+time Mumford-Shah Functional
this paper describes a new video segmentation method obtained by minimizing an extension of Mumford-Shah functional used for 2D+time partitions. This extension permits to write the MumfordShah functional as an amultiscale energy, which is minimized on a 2D+time persistent hierarchy. The building of this hierarchy based on connected components of spatio-temporal regions.
متن کاملVideo segmentation algorithm based on modified Mumford-Shah functional
In this paper we present a video segmentation procedure obtained minimizing a modified version of the simplified Mumford Shah functional used for image partition. This procedure uses a graph with spatial and temporal connections to model a video sequence. The temporal connections are defined pre-computing the dense optical flow using methods available in the literature. To simplify the function...
متن کاملFast Segmentation for the Piecewise Smooth Mumford-Shah Functional
This paper is concerned with an improved algorithm based on the piecewise-smooth Mumford and Shah (MS) functional for an efficient and reliable segmentation. In order to speed up convergence, an additional force, at each time step, is introduced further to drive the evolution of the curves instead of only driven by the extensions of the complementary functions + u and − u . In our scheme, furth...
متن کامل2D Image Segmentation Through the One Dimensional Mumford-Shah Functional
Image segmentation is a complex task, since it involves the manipulation of different kind of objects such as functions, domains in R and curves. In this work we propose a two-dimensional image segmentation method, using the Mumford and Shah’s one dimensional technique, performing vertical and horizontal sweeps. This is in contrast to the technique that involves the generalization of the Mumfor...
