中文说明：收集的nscp-pcnn图像融合代码，这里的pcnn没有优化，运算时间会较慢，希望有所帮助The paper is structured as follows. In Section II, we describe the NSCT and its building blocks.We introduce a pyramid structure that ensures the multiscale feature of the NSCT and the directional filtering structure based on the DFB. The basic unit in our construction is the nonsubsampled filter bank (NSFB) which is discussed in Section II. In Section III, we study the issues associated with the NSFB design and implementation problems. Applications of the NSCT in image denoising and enhancement are discussed in Section IV. Concluding remarks are drawn in Section V.
