• ## SEPC: using 3D convolution to extract scale invariant features from FPN, the rising point artifact | CVPR 2020

Time：2021-9-17

This paper proposes that Pconv can effectively integrate the internal relationship between scales by 3D convolution of feature pyramid and regularization with specific Ibn. In addition, this paper proposes SEPC, which uses deformable convolution to adapt to the irregularity of the correspondence between actual features and maintain scale equilibrium. Pconv and SEPC significantly improve the […]
