Deep Learning Techniques for Video Instance Segmentation: A Survey
It provides a comprehensive overview for researchers and practitioners in computer vision, but it is incremental as it synthesizes existing work rather than introducing new methods.
This survey reviews deep learning techniques for video instance segmentation, an emerging computer vision task introduced in 2019 that involves detecting, segmenting, and tracking objects in videos, and it covers various architectural paradigms, performance comparisons, and auxiliary methods.
Video instance segmentation, also known as multi-object tracking and segmentation, is an emerging computer vision research area introduced in 2019, aiming at detecting, segmenting, and tracking instances in videos simultaneously. By tackling the video instance segmentation tasks through effective analysis and utilization of visual information in videos, a range of computer vision-enabled applications (e.g., human action recognition, medical image processing, autonomous vehicle navigation, surveillance, etc) can be implemented. As deep-learning techniques take a dominant role in various computer vision areas, a plethora of deep-learning-based video instance segmentation schemes have been proposed. This survey offers a multifaceted view of deep-learning schemes for video instance segmentation, covering various architectural paradigms, along with comparisons of functional performance, model complexity, and computational overheads. In addition to the common architectural designs, auxiliary techniques for improving the performance of deep-learning models for video instance segmentation are compiled and discussed. Finally, we discuss a range of major challenges and directions for further investigations to help advance this promising research field.
