The automatic captioning pipeline can be enhanced in several ways to produce more natural and diverse descriptions of 3D human poses. Firstly, incorporating advanced natural language processing (NLP) techniques, such as transformer-based models like BERT or GPT, could improve the fluency and contextual relevance of the generated sentences. These models can better understand the nuances of language and generate more coherent and contextually appropriate descriptions.
Secondly, expanding the variety of posecodes and their relationships could lead to richer descriptions. By introducing more complex posecodes that capture nuanced body movements and interactions, the pipeline can generate descriptions that reflect a wider range of human activities and postures. Additionally, integrating a larger set of aggregation rules that consider various linguistic styles and structures could enhance the diversity of the output.
Furthermore, implementing a feedback loop where human annotators review and refine the automatically generated captions could help in fine-tuning the model. This iterative process would allow the model to learn from human preferences and improve its output quality over time. Lastly, incorporating randomness in the selection and aggregation of posecodes can help in generating multiple unique descriptions for the same pose, thereby increasing the dataset's diversity and richness.
