Training Large Multimodality Models (LMMs) relies on descriptive image
caption that connects image and language. Existing methods either distill the
caption from the LMM models or construct the captions from the internet images
or by human. We propose to leverage off-the-shelf visual specialists, which
were trained from annotated images initially not for image captioning, for
enhancing the image caption.
  Our approach, named DCE, explores object low-level and fine-grained
attributes (e.g., depth, emotion and fine-grained categories) and object
relations (e.g., relative location and human-object-interaction (HOI)), and
combine the attributes into the descriptive caption. Experiments demonstrate
that such visual specialists are able to improve the performance for visual
understanding tasks as well as reasoning that benefits from more accurate
visual understanding. We will release the source code and the pipeline so that
other visual specialists are easily combined into the pipeline. The complete
source code of DCE pipeline and datasets will be available at
