摘要
在医学技术中,医学影像学已成为发展最为迅速的领域之一•文章研究了偏微分方程模型同时在不同方向上对图像进行处理,其扩散程度的现象表明,变分偏微分比常微分方程处理的图像质量要高,边界解决问题要好,并且极大地降低了系统所需运算速度。通过将图像输入中值滤波器,利用输出结果的虚部求扩散系统,再用此系统对边缘检测函数进行8个邻域的扩散计算.根据实验结果可以得出,采用该处理模型不仅能提高图像的质量,更能保持边界不失真,效果非常显著.
In medical technology,medical imaging has become one of the fastest growing fields.This paper studied that the partial differential equation model processed the image in different directions at the same time・The phenomenon of diffusion degree shows that image quality of the variational partial differentialprocessing is higher than that of the ordinary differential equation,the boundary solving problem is better,and the operation speed of the system is greatly reduced.By inputting the image into the median filter,the imaginary part of the output result is used to find the diffusion system,and then the system performs the diffusion calculation of the eight neighborhoods of the edge detection function.According to the experimental results,it can be concluded that the processing model can not only improve the image quality,but also maintain the boundary without distortion,and the effect is very significant.
