AI This repository is the implementation of our paper: Remote Sensing Image Scene Classification Using Multiscale Feature Fusion Covariance Network With Octave Convolution. To accommodate the novel feature representation, we generalize the vanilla convolution, and propose Octave Convolution (OctConv) which takes in feature maps containing tensors of two frequencies one octave apart, and extracts information directly from the low-frequency maps without the need of decoding it back to the high-frequency as shown in Octave Convolution Implementation in PyTorch. In this work, we propose to factorize the mixed feature maps by their frequencies, and design a novel Octave Convolution (OctConv) operation to store and process feature maps that vary Octave convolution can be used as a replacement for vanilla convolution. It was noticed that Unet with octave convolutions takes nearly 2 GB less GPU memory and give almost same performance as former. Loading. Yan, Y.
