What is SAM-GAN: Self-Attention supporting Multi-stage Generative Adversarial Networks for text-to-image synthesis about?

Synthesizing photo-realistic images based on text descriptions is a challenging task in the field of computer vision. Although generative adversarial networks have made significant breakthroughs in this task, they still face huge challenges in generating high-quality visually realistic images consistent with the semantics of text. Generally, existing text-to-image methods accomplish this task with two steps, that is, first generating an initial image with a rough outline and color, and then gradually yielding the image within high-resolution from the initial image. However, one drawback of these methods is that, if the quality of the initial image generation is not high, it is hard to generate a satisfactory high-resolution image. In this paper, we propose SAM-GAN, Self-Attention supporting Multi-stage Generative Adversarial Networks, for text-to-image synthesis. With the self-attention mechanism, the model can establish the multi-level dependence of the image and fuse the sentence- and word-level visual-semantic vectors, to improve the quality of the generated image. Furthermore, a multi-stage perceptual loss is introduced to enhance the semantic similarity between the synthesized
