Active contour model based on local bias field estimation for image segmentation

作者：

Highlights：

• A new equation is proposed to compute the value of bias field.

• The computation of the bias field is completed before the iteration.

• We propose a new variational level set function.

• The proposed model shows better segmentation accuracy and robustness.
