Challenge: Existing benchmarks focus on perceptual quality, text–video alignment, or physical plausibility, leaving a critical aspect of action understanding unexplored.
Approach: They introduce a benchmark specifically designed to assess OSC performance in T2V models.
Outcome: The proposed benchmark assesses the performance of open-source and proprietary T2V models on object state change (OSC) in the context of novel and compositional scenarios.

O2NA: An Object-Oriented Non-Autoregressive Approach for Controllable Video Captioning (2021.findings-acl)

Copied to clipboard

Challenge: Existing methods for video captioning consider a sequence of frames and biases towards focused objects.
Approach: They propose an Object-Oriented Non-Autoregressive approach to video captioning . it performs three steps: 1) identify the focused objects and predict their locations . 2) generate related attribute words and relation words of these focused objects to form a draft caption .
Outcome: The proposed method achieves competitive results with the state-of-the-art methods but with higher diversity and faster inference speed.
