Abstract

This paper presents a deep learning approach to Kaggle Carvana Image Masking Competition, which aims at extracting the car objects in high quality images with the background removed. We formulate the background extraction problem as an image segmentation problem. In this challenge, we have evaluated different U-Net architectures. We have explored two different techniques in combining encoder downsampling features with decoder upsampling features. In addition, we have experimented replacing different pre-trained networks to accelerate the training process. Finally, we have trained different models at different image scales and predicted the final result with the ensemble method. Our final method has placed us at top 4% in the challenge and achieved a dice coefficient score of 0.99694.
