Abstract:
In this paper, we propose a method to improve the accuracy of semantic segmentation when the number of training data is limited. When time-series information such as video is available, it is expected that images that are close in time-series are similar to each other, and pseudo-labels can be easily assigned to those images with high accuracy. In other words, if the pseudo-labels are assigned to the images in the order of time-series, it is possible to efficiently collect pseudo-labels with high accuracy. As a result, the segmentation accuracy can be improved even when the number of training images is limited. In this paper, we evaluated our method on the CamVid dataset to confirm the effectiveness of the proposed method. We confirmed that the segmentation accuracy of the proposed method is much improved in comparison with the baseline without pseudo-labels.
