| Abstract: | Scattering transform is a novel image transform algorithm based on wavelet transform, which obtains the image features by the complex wavelet decomposition, modular arithmetic and image equalization. With the features of local translation invariant and elastic deformation stabilization, scattering transform is new research hotspot in the signal processing field in recent years. This paper discusses the scattering transform theory, its realization algorithm and some typical applications. Finally, the facing problems and research interests are pointed out. |
