The first develops a novel connection between the additive (Walsh) and multiplicative (Grace-Szeg) convolutions, which can be generically used to transfer results from multiplicative to additive. We then use this to transfer an analogous result, due to Lamprecht, which demonstrates logarithmic root ...
Difference Convolution Neural Network (DCNN) inspired by the facial expression’s nonstationary nature. In the first stage, the neutral expression frame and fully expression frame are automatically picked out from the facial expression sequences using a binary Convolution Neural Network (CNN). Then ...

Based on theCentral Difference Convolution (CDC)andContrastive Depth Loss (CDL), we achieved 1st Placein ChaLearn Multi-Modal Face Anti-spoofing Attack Detection Challenge @CVPR2020 2nd Placein ChaLearn Single-Modal(RGB) Face Anti-spoofing Attack Detection Challenge @CVPR2020 ...
'TDC' is short for the temporal difference convolution [63, 69]. 3. Methodology We will first introduce the architecture of PhysFormer in Sec. 3.1, then introduce label distribution learning for rPPG measurement in Sec. 3.2, and at last present th...
3. Linear Convolution: Methods of Computation Using linear convolution, we compute the convolution of two sequences to determine how one signal modifies another, producing an extended output sequence. To compute linear convolution for short data sequences, we use the direct formula, graphical, tabula...
