CoRR, 2023 We present a new algorithm for image segmentation - Level-set KSVD. Level-set KSVD merges the methods of sparse dictionary learning for feature extraction and variational level-set method for image segmentation. Specifically, we use a generalization of the Chan-Vese functional with features learned by KSVD.

Automatic Brain Tumor Segmentation in Multimodal Magnetic Resonance Images (MRI) Using Brain Symmetry Analysis and Active Contour [PDF]
مجله علوم پزشکی صدرا, 2000 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.

Early and accurate detection of melanoma skin cancer using hybrid level set approach
Frontiers in Physiology, 2022 Digital dermoscopy is used to identify cancer in skin lesions, and sun exposure is one of the leading causes of melanoma. It is crucial to distinguish between healthy skin and malignant lesions when using computerised lesion detection and classification.
