利用密度的指数原理优化X射线中骨骼的边缘

Applying Exponent Method of Density to Amend Bone's Edge of X-ray Image

利用指数衰减原理来抑制 x射线图像中小密度组织对骨骼边缘的影响 ,利用该方法很容易使用直方图原理提取出骨骼的边缘和内部结构变化的二值图 ,并有效地抑制了背景对骨骼边缘的影响 ,结合 canny算子的结果 ,可以有效地提取人体复杂结构中骨骼的边缘。

Because of the difference in organic density, a simple and effective method for exponent restraint of active edge is applied to X-ray image of bone. And it is easy to use histogram method to get the active image of bone. At last, by associating it with Canny method, the edge of bone can be abstracted from a complex X-ray image.
