摘要
文章提出了一种基于Sobel算子和网格的二尺度彩色图像边缘检测方法。该方法将图像划分成预先设定大小的网格，在两个尺度上对图像进行分析，完成图像的边缘检测。应用该方法可以对海上彩色目标进行目标特性提取，提高对海上威胁目标的预警能力。
The method of two-scale color image edge detection based on Sobel operator and grid is proposed in this paper. Firstly, an image is divided into pre-defined size of grid, and the image is analyzed on two-scale, the image edge detection is finished finally. Applying this method can extract color target characteristics and improve early warning ability of sea thereat target.
