The paper introduces ToddlerAct, a specialized dataset for toddler action recognition, and benchmarks multiple methods to advance research in early motor development assessment.
Findings
Domain-specific datasets improve accuracy in toddler motor assessment
State-of-the-art methods show varying performance on toddler actions
Dataset availability will facilitate future research in early childhood development
Abstract
Assessing gross motor development in toddlers is crucial for understanding their physical development and identifying potential developmental delays or disorders. However, existing datasets for action recognition primarily focus on adults, lacking the diversity and specificity required for accurate assessment in toddlers. In this paper, we present ToddlerAct, a toddler gross motor action recognition dataset, aiming to facilitate research in early childhood development. The dataset consists of video recordings capturing a variety of gross motor activities commonly observed in toddlers aged under three years old. We describe the data collection process, annotation methodology, and dataset characteristics. Furthermore, we benchmarked multiple state-of-the-art methods including image-based and skeleton-based action recognition methods on our datasets. Our findings highlight the importance…
