摘要:

像下雨或灰尘这样的相机异常会严重降低图像质量及其相关任务,如定位和分割。在这项工作中,我们通过实施预处理步骤来解决这一重要问题,该预处理步骤可以有效地以实时方式减轻此类伪影,从而支持具有有限计算能力的自治系统的部署。我们提出了一个具有聚合的浅层生成器,在对抗环境中进行训练,以解决重建遮挡区域的不适定问题。我们添加了一个增强器来进一步保留高频细节和图像彩色化。我们还制作了一个最大的公开可用的训练器1来训练我们的架构,并使用逼真的合成雨滴来获得改进的模型初始化。我们在现有的数据集和我们自己的图像上对我们的框架进行基准测试,获得最先进的结果,同时实现实时的每一次测试,推理时间比现有方法快40倍。

英文摘要:

Camera anomalies like rain or dust can severelydegrade image quality and its related tasks, such as localizationand segmentation. In this work we address this importantissue by implementing a pre-processing step that can effectivelymitigate such artifacts in a real-time fashion, thus supportingthe deployment of autonomous systems with limited computecapabilities. We propose a shallow generator with aggregation,trained in an adversarial setting to solve the ill-posed problemof reconstructing the occluded regions. We add an enhancer tofurther preserve high-frequency details and image colorization.We also produce one of the largest publicly available datasets1to train our architecture and use realistic synthetic raindrops toobtain an improved initialization of the model. We benchmarkour framework on existing datasets and on our own imagesobtaining state-of-the-art results while enabling real-time per-formance, with up to 40x faster inference time than existingapproaches.
