Remote sensing image captioning via Variational Autoencoder and Reinforcement Learning

作者:

Highlights:

• Introducing VAE to regularize the shared encoder and extract image features more effectively by reconstructing input images.

• Improving the performance of image caption significantly by virtue of low-level and high-level image features simultaneously.

• Enhancing the final text description quality by adding self-attention to spatial features.

• Our proposed model outperforms the state-of-the-art models in the remote sensing image captioning.
