B-Spline Active Contour with Handling of Topology Changes for Fast Video Segmentation
EURASIP Journal on Advances in Signal Processing, 2002 This paper deals with video segmentation for MPEG-4 and MPEG-7 applications. Region-based active contour is a powerful technique for segmentation. However most of these methods are implemented using level sets. Although level-set methods provide accurate

Active Contours with Group Similarity [PDF]
2013 IEEE Conference on Computer Vision and Pattern Recognition, 2013 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 ...

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...

Extended Active Contour Algorithm Based on Color Variance
Journal of Measurement Science and Instrumentation, 2010 General active contour algorithm,which uses the intensity of the image,has been used to actively segment objects.Because the objects have a similar intensity but different colors,it is difficult to segment any object from the others.Moreover,this ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Timely cancer diagnosis in children and adolescents is important to improving outcomes. We aimed to quantify time to diagnosis and assess variations by patient, demographic and system‐level factors. Procedure We conducted a population‐based study of individuals aged 0–19 years diagnosed with one of 12 cancers from 2010 to 2022 in ...
