摘要:

已经表明,当呈现失真图像时,经过完美训练的网络表现出性能的急剧下降。流网络(STNet)是一种新的架构,能够鲁棒的分类失真的图像,而在未失真的图像进行训练。失真鲁棒性通过稀疏输入和具有解耦权重的隔离并行流来实现。最近的结果证明STNet对20种类型的噪声和失真具有鲁棒性。STNet在低光图像分类方面表现出最先进的性能,而其他网络的尺寸要小得多。在本文中,我们通过使用VGG16,ResNet50和MobileNetV2等流行网络的缩放版本(每层中的过滤器数量减少了n倍)作为并行流来构建STNet。这些新的STNet在几个数据集上进行了测试。我们的结果表明,与原始网络相比,更高效(更少的FLOPS)的新STNet表现出更高或同等的准确性。考虑到用于测试的数据集和网络的多样性,我们得出结论,一种新型的STNet是一种有效的工具,用于对失真图像进行鲁棒分类。

英文摘要:

It has been shown that perfectly trained networks exhibit drastic reduction in performance when presented with distorted images. Streaming Network (STNet) is a novel architecture capable of robust classification of the distorted images while been trained on undistorted images. The distortion robustness is enabled by means of sparse input and isolated parallel streams with decoupled weights. Recent results prove STNet is robust to 20 types of noise and distortions. STNet exhibits state-of-the-art performance for classification of low light images, while being of much smaller size when other networks. In this paper, we construct STNets by using scaled versions (number of filters in each layer is reduced by factor of n) of popular networks like VGG16, ResNet50 and MobileNetV2 as parallel streams. These new STNets are tested on several datasets. Our results indicate that more efficient (less FLOPS), new STNets exhibit higher or equal accuracy in comparison with original networks. Considering a diversity of datasets and networks used for tests, we conclude that a new type of STNets is an efficient tool for robust classification of distorted images.
