Figure 1. Comparing generative open-ended object detection with
other open-set object detection tasks. Open-vocabulary object de-
tection and phrase grounding typically require predefined cate-
gories or phrases in text prompts to align with image regions. In
contrast, our introduced generative open-ended object detection is
a more general and practical setting where categorical information
is not explicitly defined. Such a setting is especially meaningful
for scenarios where users lack precise knowledge of object cate-
gories during inference.
