Abstract: Road scene understanding is an important module in autonomous driving as it can provide rich information for other modules like high-res map and dynamic planning. Semantic segmentation classifies each pixel in an image and it is often used in scene understanding. However, common segmentation algorithms cannot balance the accuracy and speed. In this paper, we first extract features with light-weight backbone MobileNetV2, and then introduce a new feature fusion module to combine multi-scale features efficiently, which can makes a good balance between accuracy and speed. Finally, we evaluate our method on the Cityscapes dataset.

Key words: autonomous driving, semantic segmentation, scene understanding, deep learning, multi-scale feature fusion
