We propose four new fusion difference convolution (FDC) structures that integrate traditional gradient operators into modern CNNs. At the same time, we have also added a channel spatial attention module (CSAM) and an up-sampling module (US). These structures allow the model to better recognize ...
4.1 Pixel Difference Convolution(PDC) 一个公式,一张图,一段文字搞清楚。 传统的卷积处理的是:特征的值。(1式) PDC处理的是:像素差值,也就是pair的差。(2式) 那么如何实现PDC呢?重点就是这个pair:四周与中心(CPDC),四周循环(APDC),径向方向(RPDC)。这些奇怪的操作哪来的?看一看作者自己写的博文:(这是一...
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 ...

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...
