A New Edge Detection Method for CT-Scan Lung Images
Lung cancer is one of the most serious health problems in the world. Lung Computer-Aided Diagnosis (CAD) is a potential method to accomplish a range of quantitative tasks such as early cancer and disease detection, analysis of disease progression. Edge detection in Lung image is a fundamental step in CAD system and many algorithms have suggested for edge detection in image. In this paper a new ...
متن کاملA Hybrid Method for Segmentation and Visualization of Teeth in Multi-Slice CT scan Images
Introduction: Various computer assisted medical procedures such as dental implant, orthodontic planning, face, jaw and cosmetic surgeries require automatic quantification and volumetric visualization of teeth. In this regard, segmentation is a major step. Material and Methods: In this paper, inspired by our previous experiences and considering the anatomical knowledge of teeth and jaws, we prop...
متن کاملEdge Detection from Ct Images of Lung
Lung Cancer detection is important since if doctor may detect it earlier then it is easy to them to diagnose and may be possible to recover the disease in the early stage. It is one of the first growing diseases now a day in the world. This paper provides a method using Computer Aided Diagnosis System (CAD) for detection of edges from CT images of lung for detection of diseases.
متن کاملSegmentation of Multiple Salient Closed Contours from Real Images
Using a saliencymeasure based on the global property of contour closure, we have developed a segmentationmethodwhich identifies smooth closed contours bounding objects of unknown shape in real images. The saliency measure incorporates the Gestalt principles of proximity and good continuity that previous methods have also exploited. Unlike previous methods, we incorporate contour closureby findi...
متن کاملSegmentation of Preprocessed MR and CT Images Containing Tumors using Edge Detection and Watershed Segmentation
Segmentation of images aims at dividing areas corresponding to different objects. There are two approaches for image segmentation, one is based on discontinuities and other is based on similarities. These approaches can be used for enhancing and extracting the tumor area in MRI/CT images. In this paper Sobel and Extended Sobel edge operators are applied on the MRI / CT images containing tumors....
