چکیده

barrett's mucosa is one of the most important diseases in upper gastrointestinal system that caused by gastroesophagus reflux. if left untreated, the disease will cause distal esophagus and gastric cardiaadenocarcinoma. the malignancy risk is very high in short segment barrett’s mucosa. therefore,lesion area segmentation can improve specialist decision for treatment. in this paper, we proposeda combined fuzzy method with active models for barrett’s mucosa segmentation. in this study,we applied three methods for special area segmentation and determination. for whole disease areasegmentation, we applied the hybrid fuzzy based level set method (lsm). morphological algorithmswere used for gastroesophageal junction determination, and we discriminated barrett’s mucosa from breakby applying chan-vase method. fuzzy c-mean and lsms fail to segment this type of medical imagedue to weak boundaries. in contrast, the full automatic hybrid method with correlation approachthat has used in this paper segmented the metaplasia area in the endoscopy image with desirableaccuracy. the presented approach omits the manually desired cluster selection step that needed theoperator manipulation. obtained results convinced us that this approach is suitable for esophagusmetaplasia segmentation.

A Hybrid Segmentation Framework using Level Set Method for Confocal Microscopy Images

Based on variational and level set approaches, we present a hybrid framework with quality control for confocal microscopy image segmentation. First, nuclei are modelled as blobs with additive noise and a filter derived from the Laplacian of a Gaussian kernel is applied for blob detection. Second, nuclei segmentation is reformulated as a front propagation problem and the energy minimization is o...

Segmentation of the Weld Radiographic Images by the Level Set Method using the Kernel Fuzzy C-Means Clustering

In this paper, we are interested to segment weld radiographic images using the level set method (LSM) based on kernel fuzzy c-means clustering (KFCM) in order to extract the region of interest (weld defects) and to improve the precision of segmentation. The proposed approach contains two successive necessary stages. The first one consists in the application of kernel fuzzy c-means algorithm to ...

Segmentation of Images Using Level Set Analysis

We propose an image segmentation technique using level set analysis. Image level set is the binary decomposition of a gray level image. Connected components in the level set, less than a pre-defined size are removed from the level set. Based on level set topology an exposed connected component is defined in the level set. These exposed connected components are merged based on a proximity value ...
