异质扩散的图像边缘特征提取方法

Edge feature extraction of anisotropic diffusion images

图像检测中提高成像的质量、抑制图像的噪声、增强图像的对比度是图像检测的主要目标。其主要目的是为了强化边缘特点,方便进行具体的测量。针对偏微分方程(PDE)在图像处理中的运用进行了探讨,并将其与形态学腐蚀算子相结合,提出了基于形态学腐蚀和梯度计算的边缘检测方法,并通过仿真测试进行验证。

To raise the quality of imaging,to suppress the noise and enhance the contrast is the main purpose of image detection.To reinforce the edge feature will help specific measurement.The application of Partical Differential Equation（PDE） in image processing was introduced,and combined with the erosion operator in mathematical morphology.The edge detection method based on erosion operator and grad computation was proposed,simulated and validated.
