Human Action Recognition (HAR) aims to understand human behavior and assign a label to
each action. It has a wide range of applications, and therefore has been attracting increasing …

Most existing action quality assessment methods rely on the deep features of an entire video
to predict the score, which is less reliable due to the non-transparent inference process and …

To understand human behaviors, action recognition based on videos is a common
approach. Compared with image-based action recognition, videos provide much more …

Action recognition is one of the challenging video understanding tasks in computer vision.
Although there has been extensive research in the task of classifying coarse-grained …

Existing action quality assessment (AQA) methods mainly learn deep representations at the
video level for scoring diverse actions. Due to the lack of a fine-grained understanding of …

Few-shot action recognition aims to recognize novel action classes using only a small
number of labeled training samples. In this work, we propose a novel approach that first …

Few-shot action recognition aims to address the high cost and impracticality of manually
labeling complex and variable video data in action recognition. It requires accurately …

We introduce the task of spotting temporally precise, fine-grained events in video (detecting
the precise moment in time events occur). Precise spotting requires models to reason …

Trajectory estimation is a fundamental component of racket sport analytics, as the trajectory
contains information not only about the winning and losing of each point, but also how it was …

The availability of vast video collections and the accuracy of ML models has generated
significant interest in video analytics systems. Since naively processing all frames using …
