| 摘 要： | 在纤维显微照片拍摄过程中,显微镜点光源引起的图像光照不均问题对纤维识别处理算法带来影响.提出基于迭代法的光照不均修正算法,在消除光照影响的同时,保存纤维的形态信息.对迭代误差进行控制,获取误差收敛时的迭代次数.实验证明,算法在保存纤维信息的同时,有效地抑制了光照不均的影响.

| Abstract: | When the nature fiber's image is being taken through microscope,nonuniform illumination caused by microscope's point source would make badly influence on natural fiber image processing. An iterative algorithm is proposed that can eliminate illumination influence on fiber image,along with reserving fiber's shape information. With controlling the error of iteration,the iteration degree can be obtained when the error of iteration is convergent. The experiment evident proves that the algorithm proposed can preserve the nature fiber's shape information,as well as efficiently control the influence caused by nonuniform illumination. |
