| 摘 要： | 图像检测中如何提高成像的质量,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。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(Partial Differential Equations)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。

| Abstract: | In image detection,how to improve the imaging quality,restrain image noise and enhance image contrast are the main objectives.Its main purpose is to intensify edge characteristics for the convenience of specific measurement.In this article we present the discussion aiming at the application of partial differential equations(PDE) in image processing.Moreover,by combining it with the morphological corrosion operator,we propose an edge detection method which is based on morphological corrosion and gradient calculation,and have validated the method through simulation tests. |
