【摘要】 提出了一种基于有限邻域EMD(Neighborhood Limited Empirical Mode Decomposition)与小波分析相结合的图像边缘检测方法。首先将图像信号进行有限邻域EMD分解,将其分解成n个IMF(Intrinsic Mode Function)函数,再对每个IMF函数进行小波变换。将该方法应用于图像的边缘提取,较好地得到了图像的边缘信息。更多还原

【Abstract】 An effective algorithm of image edge detection based on neighborhood limited empirical mode decomposition and wavelet analysis is presented.The image signal is decomposed to a number of IMF function via neighborhood limited EMD,then each IMF function is processed by wavelet transform.The application of this method to image shows that it is effective and practical.更多还原
