摘要
将C-V模型引入到红外图像分割中,同时提出了一种改进的模型。该模型通过增加偏离能量项,避免了标准C-V模型的重新初始问题。模型允许选取较大的时间步长,可以用简单的有限差分格式实现。实验证明,改进的模型在分割效果不变的情况下可以有效加速演化过程,提高分割效率。
The C - V model is introduced into the infrared image segmentation, and an improved C - V model is pro- posed. This improved model avoids the problem of re-initialization in the normal C - V model by adding a deviatory term into the C -V model. It can be implemented by simple finite difference scheme with a significantly larger time step. The experimental results show that the improved C - V model can speed up the evolution and make the segmentation more efficient while there is no degradation in the segmentation result.
