基于二值图像连通域提取的图像滤波方法

An Image Filtering Method to Extract Connected Domain in Binary Image

为解决常用滤波方法对目标图像噪声抑制效果不理想的问题,提出了一种基于二值图像连通域提取的图像滤波方法。将采集到的图像进行二值化,对图像进行连通域提取并根据连通域的轮廓筛选出噪声干扰点,对噪声点进行过滤,保留图像细节特征,对目标图像的噪声达到有效抑制的效果。结果表明:该方法在特定应用上优于常规滤波方法。

In order to address the noise suppression effect is not as ideal as expected,when using common noise filtering method to suppress the target image,it presents an image filtering method to extract connected domain in binary image. The collected binary image extracts the images connected domain and communicates according to the outline of the selected field noise point and filter noise point,ultimately preserves image detail and effective noise suppression characteristics of the target image. Results show that this method is superior to conventional filtering methods in a particular application.
