摘要

由于对高阶矩的敏感性和相对于小变形的连续性,第二层散射描述符在视觉纹理等自然准平稳过程中提供了良好的分类性能。在功能磁共振成像(fMRI)实验中,我们向受试者展示视觉纹理,并评估这些描述符相对于简单轮廓能量-第一散射层的预测能力的预测能力。我们不仅可以得出不变的第二层散射系数更好地编码体素活动的结论,而且可以得出预测良好的体素不一定位于已知的视网膜异位区域。

Second Order Scattering Descriptors Predict fMRI Activity Due to Visual Textures
Second layer scattering descriptors are known to provide good classification performance on natural quasi-stationary processes such as visual textures due to their sensitivity to higher order moments and continuity with respect to small deformations. In a functional Magnetic Resonance Imaging (fMRI) experiment we present visual textures to subjects and evaluate the predictive power of these descriptors with respect to the predictive power of simple contour energy - the first scattering layer. We are able to conclude not only that invariant second layer scattering coefficients better encode voxel activity, but also that well predicted voxels need not necessarily lie in known retinotopic regions.
