摘要:

我们提出了AMOS补丁,一个大型的图像裁剪集,主要用于可训练的局部特征描述符对照明和外观变化的鲁棒化。贡献给AMOS补丁的图像来源于AMOS数据集,该数据集记录了大量户外网络摄像头。介绍了AMOS补丁的半自动生成方法。它包括摄像机选择,视点聚类和补丁选择。对于训练,我们提供注册的完整源图像以及补丁。介绍了一种在AMOS Patches和6Brown数据集上训练的新描述符。它实现了最先进的匹配下的照明变化的标准基准。

英文摘要:

We present AMOS Patches, a large set of image cut-outs, intended primarily for the robustification of trainable local feature descriptors to illumination and appearance changes. Images contributing to AMOS Patches originate from the AMOS dataset of recordings from a large set of outdoor webcams. The semiautomatic method used to generate AMOS Patches is described. It includes camera selection, viewpoint clustering and patch selection. For training, we provide both the registered full source images as well as the patches. A new descriptor, trained on the AMOS Patches and 6Brown datasets, is introduced. It achieves state-of-the-art in matching under illumination changes on standard benchmarks.
