摘要:

深度学习方法需要足够的训练样本才能表现良好,但收集足够多的真实训练数据并手动标记它们是一个挑战。在这封信中,我们建议使用现实的合成数据与广泛的分布,以提高遥感图像飞机检测的性能。具体来说,为了增加合成数据的可变性,我们在渲染过程中随机设置参数,例如实例的大小和背景图像的类别。为了使合成图像更加逼真,我们使用CycleGAN在像素级上对真实的未标记图像进行优化。我们还用少量的实际数据对模型进行了微调,以获得更高的精度。在NWPU VHR-10、UCAS-AOD和DIOR数据集上的实验表明,该方法可以用于增强不充分的真实数据。

英文摘要:

Deep learning approaches require enough training samples to perform well, but it is a challenge to collect enough real training data and label them manually. In this letter, we propose the use of realistic synthetic data with a wide distribution to improve the performance of remote sensing image aircraft detection. Specifically, to increase the variability of synthetic data, we randomly set the parameters during rendering, such as the size of the instance and the class of background images. In order to make the synthetic images more realistic, we then refine the synthetic images at the pixel level using CycleGAN with real unlabeled images. We also fine-tune the model with a small amount of real data, to obtain a higher accuracy. Experiments on NWPU VHR-10, UCAS-AOD and DIOR datasets demonstrate that the proposed method can be applied for augmenting insufficient real data.
