A Modification of the Mumford-Shah Functional for Segmentation of Digital Images with Fractal Objects
نویسندگان
چکیده
In this paper we revisit the Mumford-Shah functional, one of the most studied variational approaches to image segmentation. The contribution of this work is to propose a modification of the Mumford-Shah functional that includes Fractal Analysis to improve the segmentation of images with fractal or semifractal objects. Here we show how the fractal dimension is calculated and embedded in the functional minimization computation to drive the algorithm to use both, changes in the image intensities and the fractal characteristics of the objects, to obtain a more suitable segmentation. Experimental results confirm that the proposed modification improves the quality of the segmentation in images with fractal objects or semi fractal such as medical images.

Efficient Bottom-Up Image Segmentation Using Region Competition and the Mumford-Shah Model
Curve evolution implementations of the MumfordShah functional are of broad interests in image segmentation. These implementations, however, have initialization problems. A mathematical analysis of the initialization problem for the Chan-Vese implementations is provided in this paper. The initialization problem is shown to result from the non-convexity of the Mumford-Shah functional and the top-...
متن کاملMulti-scale Segmentation of High Resolution Remote Sensing Images by Integrating Multiple Features
Most of multi-scale segmentation algorithms are not aiming at high resolution remote sensing images and have difficulty to communicate and use layers’ information. In view of them, we proposes a method of multi-scale segmentation of high resolution remote sensing images by integrating multiple features. First, Canny operator is used to extract edge information, and then band weighted distance f...
متن کاملJoint prior models of mumford-shah regularization for blur identification and segmentation in video sequences
We study a regularized Mumford-Shah functional in the context of joint prior models for blur identification, blind image deconvolution and segmentation. For the ill-posed regularization problem, it is hard to find a good initial value for ensuring the soundness of the convergent value. A newly introduced prior solution space of point spread functions in a double regularized Bayesian estimation ...
متن کاملA Piecewise Constant Region Based Simultaneous Image Segmentation and Registration
A new variational region based model for a simultaneous image segmentation and a rigid registration is proposed. The purpose of the model is to segment and register novel images simultaneously using a modified piecewise constant Mumford-Shah functional and region intensity values. The segmentation is obtained by minimizing a modified piecewise constant Mumford-Shah functional. A registration is...
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...
