| 摘要: |
| 针对指纹快速细化算法中存在双像素宽的情况,研究快速细化后像素的8邻域像素值的特征,通过计算8邻域像素值的和以及8邻域中相邻像素间的关系,对快速细化算法进行改进,使细化的结果为单像素宽。改进的算法对指纹的细化效果好,速度快,效率高。 |

| Abstract: |
| The characteristics of eight-neighbor pixels were studied to solve the problem of double pixels width in the quick thinning algorithm.By computing the sum of eight-neighbor pixel values and researching the relationship between the adjacent eight-neighbor pixels,an improved quick thinning algorithm is proposed.The result in the improved algorithm becomes one pixel width.The experimental results show that the improved algorithm runs quick and efficient. |
| Key words: quick thinning fingerprint image one pixel wide eight-neighbor |
