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