Evaluation of Semi-automatic Segmentation Methods for Persistent Ground Glass Nodules on Thin-Section CT Scans [PDF]
ObjectivesThis work was a comparative study that aimed to find a proper method for accurately segmenting persistent ground glass nodules (GGN) in thin-section computed tomography (CT) images after detecting them.MethodsTo do this, we first applied five ...

Automatic Brain Tumor Segmentation in Multimodal Magnetic Resonance Images (MRI) Using Brain Symmetry Analysis and Active Contour [PDF]
Introduction: The abnormal growth of the brain cells leads to a brain tumor, which has the highest mortality rate. Brain tumor segmentation from magnetic resonance images (MRI) separate the abnormal mass of tissue from normal brain tissues.

Active Contours with Group Similarity [PDF]
Active contours are widely used in image segmentation. To cope with missing or misleading features in images, researchers have introduced various ways to model the prior of shapes and use the prior to constrain active contours. However, the shape prior is usually learnt from a large set of annotated data, which is not always accessible in practice ...

LBP-guided active contours [PDF]
This paper investigates novel LBP-guided active contour approaches to texture segmentation. The local binary pattern (LBP) operator is well suited for texture representation, combining efficiency and effectiveness for a variety of applications. In this light, two LBP-guided active contours have been formulated, namely the scalar-LBP active contour (s ...

ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

Spectrogram Track Detection: An Active Contour Algorithm [PDF]
In many areas of science, near-periodic phenomena represent important information within time-series data. This thesis takes the example of the detection of non-transitory frequency components in passive sonar data, a problem which finds many ...
