Brain tumor segmentation in MR images using a sparse constrained level set algorithm

作者：

Highlights：

• Automatically locate brain tumors and generate initial contours in MR images.

• Construct a sparse shape constraint and incorporate it into the energy function.

• Improve the performance of level set method in segmenting complex brain tumor.
