Automatic Captioning of Open Visual World

Talk by Qin JIN

Dec 08, 2023 Friday


Automatically generating natural language descriptions of the visual content has been one of the representative tasks that bridge computer vision and natural language processing. In recent years, it has attracted extensive research attention in the vision and language communities. In this talk, I will first present our recent works on solving the “overly generic” issue of generated captions. Specifically, we propose an annotation-free, light-weight and plug-and-play framework to generate more descriptive captions based on vision-language pre-trained models. Furthermore, we attempt to solve the overly generic problem from the root and propose a new learning goal, semipermeable maximum likelihood estimation. to optimize the model to generate more detailed captions. Lastly, I will introduce our newly proposed task, embodied visual captioning in 3D environment, which aims to overcome the previous limitations of visual captioning systems relying on given high-quality images. It will enable intelligent agents that can autonomously navigate in 3D environments and actively acquire visual information to generate captions.
