摘要
一种基于小波变换的边缘提取方法,应用其对舰船图像进行边缘提取,以二次光滑小波作为小波函数,对海上舰船图像进行了二维小波变换,计算小波变换结果的局部模极大值点,从而得到舰船目标图像的形状边缘特征。经过和运用Sobel算子、Roberts算子、Prewitt算子、基于图谱理论的阈值分割等方法所获得的舰船目标结果进行比较,图像处理的结果表明运用小波变换方法所提取的目标边缘对海上舰船目标的识别有良好的效果。
Introduce an edge abstraction method based on wavelet transform. Use the method on warship image＇s edge abstractions. Put up two-dimensional wavelet transform on warship images, and calculate partial model＇s maximum point of the wavelet transform results, hence get the warship image＇s shape edge characters. Compare the techniques with methods of applying arithmetic operators like Sobel operators, Roberts operators, Prewitt operators, and threshold division based on atlas theory, the image manipulation result shows the wavelet transform method has good effect.
