where eNLBF is the NLBF energy term, shown by Eq. (2); eCV is the CV
energy term, shown by Eq. (5); x is the adaptive balance coefficient
as given by Eq. (11). Next we explain each item of Eq. (1) in detail.
First we state that all the operations in segmentation stage are for
the gray images obtained from the captured color images.
The NLBF absorbs the image contrast as a new item based on
the LBF model, which can accelerate evolution near to areas with
different image contrast. It is given by
