• Abstract summary: We propose a novel Multi-stage Contrastive Regression (MCoRe) framework for the action quality assessment (AQA) task. Inspired by the graph contrastive learning, we propose a new stage-wise contrastive learning loss function to enhance performance. MCoRe demonstrates the state-of-the-art result so far on the widely-adopted fine-grained AQA dataset.

• Abstract: In recent years, there has been growing interest in the video-based action quality assessment (AQA). Most existing methods typically solve AQA problem by considering the entire video yet overlooking the inherent stage-level characteristics of actions. To address this issue, we design a novel Multi-stage Contrastive Regression (MCoRe) framework for the AQA task. This approach allows us to efficiently extract spatial-temporal information, while simultaneously reducing computational costs by segmenting the input video into multiple stages or procedures. Inspired by the graph contrastive learning, we propose a new stage-wise contrastive learning loss function to enhance performance. As a result, MCoRe demonstrates the state-of-the-art result so far on the widely-adopted fine-grained AQA dataset.

  Action Assessment (AQA) aims at automatic and fair evaluation of athletic performance. Current methods focus on segmenting video into fixed frames, which disrupts the temporal continuity of sub-actions. We propose a novel action quality assessment method through hierarchically pose-guided multi-stage contrastive regression.

  Action quality assessment (AQA) algorithms predominantly focus on actions from real specific scenarios and are pre-trained with normative action features. We construct GAIA, a Generic AI-generated Action dataset, by conducting a large-scale subjective evaluation from a novel causal reasoning-based perspective. Results show that traditional AQA methods, action-related metrics in recent T2V benchmarks, and mainstream video quality methods perform poorly with an average SRCC of 0.454, 0.191, and 0.519, respectively.

  Action Quality Assessment (AQA) is a task that tries to answer how well an action is carried out. Existing works on AQA assume that all the training data are visible for training at one time, but do not enable continual learning. We propose a unified model to learn AQA tasks sequentially without forgetting.
