中文说明：强度不均匀性经常发生在真实世界的图像，可能会导致在图像分割中相当大的困难。 为了克服强度不均匀性所引起的困难，我们提出一种基于区域活跃的轮廓模型吸取强度信息在本地区域在可控范围内。数据拟合能量定义轮廓和两个局部近似轮廓线的两侧的图像强度的拟合函数。
English Description：
Intensity inhomogeneities often occur in real-world images and may cause considerable difficulties in image segmentation. In order to overcome the difficulties caused by intensity inhomogeneities, we propose a region-based active contour model that draws upon intensity information in local regions at a controllable scale. A data fitting energy is defined in terms of a contour and two fitting functions that locally approximate the image intensities on the two sides of the contour.
