A Novel Multi-focus Image Fusion Method using Pulse Coupled Neural Network in Nonsubsampled Contourlet Transform Domain

In this paper, a novel image fusion method is proposed which combines nonsubsampled contourlet transform (NSCT) with PCNN. Firstly, it makes use of the NSCT’s shift invariance to suppress the pseudo-Gibbs phenomena around singularities, which appears in the DWT. Secondly, the edge feature is used to motive the improved PCNN model, to retain more edge and… (More)
