Local atlas selection for discrete multi-atlas segmentation

Posted on February 2, 2016 by Matlab-Projects |

Multi-atlas segmentation is commonly performed in two separate steps: i) multiple pairwise registrations, and ii) fusion of the deformed segmentation masks towards labeling objects of interest. In this paper we propose an approach for…

An Automated Method to Parameterize Segmentation Scale by Enhancing Intrasegment Homogeneity and Intersegment Heterogeneity

Posted on February 2, 2016 by Matlab-Projects |

mage segmentation is a key step in geographic object-based image analysis. Numerous segmentationtechniques, e.g., watershed segmentation, mean-shift segmentation, and fractal net evolution algorithm, have been proposed and applied for various types of image analysis tasks.…

Modularity-Based Image Segmentation

Posted on February 2, 2016 by Matlab-Projects |

To address the problem of segmenting an image into sizeable homogeneous regions, this paper proposes an efficient agglomerative algorithm on the basis of modularity optimization. Given an oversegmented image that…

A combined watershed segmentation approach using k-means clustering for mammograms

Posted on February 2, 2016 by Matlab-Projects |

Identification and segmentation of mass are critical for medical image processing. In this paper a combined approach for image segmentation based on watershed transform and k-means clustering is proposed. A preprocessing step is applied…

Low-Complexity Topological Derivative-Based Segmentation

Posted on February 2, 2016 by Matlab-Projects |

Topological derivative has been employed for image segmentation and restoration. The topological derivative-based segmentation uses two sparse matrices, and the computational complexity of thesegmentation grows up dramatically as the image size increases due to the…

Multiple template deformation application to abdominal organ segmentation

Posted on February 2, 2016 by Matlab-Projects |

We propose a fast, automatic and versatile framework for the segmentation of multiple anatomical structures from 2D and 3D images. We extend the work of [1] on implicit template deformation to multiple…

Automatic localization and segmentation of optic disc in fundus image using morphology and level set

Posted on February 2, 2016 by Matlab-Projects |

Optic disc (OD) localization and segmentation are important in developing systems for automated diagnosis of various serious ophthalmic pathologies. This paper presents a new, fast and robust methodology for fully automatic localization…

Enhanced hybrid algorithms for compound image segmentation

Posted on February 2, 2016 by Matlab-Projects |

Image segmentation divides the image into different regions. Accurate segmentation of objects of interest in an image gently facilitates further analysis of the objects. There are three compound imagesegmentation methods for compound image compression which…

Hierarchies and shape-space for pet image segmentation

Posted on February 2, 2016 by Matlab-Projects |

Positron Emission Tomography (PET) image segmentation is essential for detecting lesions and quantifying their metabolic activity. Due to the spatial and spectral properties of PET images, most methods rely on intensity-based strategies.…

Automated segmentation of intraretinal cystoid macular edema for retinal 3D OCT images with macular hole

Posted on February 2, 2016 by Matlab-Projects |

An automated method is proposed to segment and quantify the volume of cystoid macular edema (CME) for the abnormal retina with macular hole (MH) in 3D OCT images. The proposed…
