轮胎透视图的一种整体区域分割方法

An Integer Region Segmentation Method of Tyre Scenograph

针对轮胎透视图,本文提出了一种基于三次均匀B样条和多分辨率小波的整体区域分割方法。该方法首先根据轮胎透视图建立数学模型,获得一系列离散数据点;然后通过三次均匀B样条插值得到含有噪声的灰度变化曲线,并利用多分辨率小波进行去噪处理,得到光顺曲线;最后求解曲线一阶导数的最大、最小值,得到目标区域和背景区域的两个边界。实验结果表明,该方法分割速度快,效果十分理想。

The author proposes an integer region segmentation method for type scenograph which is based on cubic uniform B-Splines and multiresolution wavelet. A math model is constructed first according to the images and a series of discrete points are gained. Then, a curve of gray changes with yawp is got by the interpolation of cubic uniform B-Splines. A smooth curve is obtained after de-noising by multiresolution wavelet. Finally, the maximum and minimum of the first order derivate of this curve are computed, and the two edges between the target region and the background region are obtcined. Experimental results indicate that the speed of segmentation is very high and the effect is very good.
