摘要
散射变换是基于小波变换的图像变换新方法,通过迭代方向复小波分解、模运算及局部平均获取图像的特征描述,具有局部平移不变性和弹性形变稳定性,是近年来信号处理领域的研究新热点.介绍了散射变换的原理,实现算法和一些典型应用,并指出所面临的问题和研究方向.
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.
