A shape-initialized and intensity-adaptive level set method for auroral oval segmentation
An intensity-adaptive level set is proposed to obtain the auroral oval boundary. A saliency morphological map is constructed to initialize the level set. The proposed method can segment not only full oval images, but also the gap oval ones. The segmentation result is a complete boundary without any leak.
