PSConv: Squeezing Feature Pyramid into One Compact Poly-Scale Convolutional Layer [article]

Duo Li, Anbang Yao, Qifeng Chen
2020 arXiv   pre-print
The proposed convolution operation, named Poly-Scale Convolution (PSConv), mixes up a spectrum of dilation rates and tactfully allocate them in the individual convolutional kernels of each filter regarding  ...  a single convolutional layer.  ...  Each specific feature scale in one pyramid layer can be grasped with a collection of convolutional kernels in a PSConv operation with the same corresponding dilation rate, thus the whole feature pyramid  ...
