Abstract
Currently, massive video inference tasks are processed through edge-cloud collaboration. However, the diverse scenarios make it difficult to allocate the inference tasks efficiently, resulting in many wasted resources. In this paper, we propose a joint-aware video processing (JAVP) architecture for edge-cloud collaboration. First, we develop a multiscale complexity-aware model for predicting task complexity and determining its suitability for edge or cloud servers. The task is subsequently efficiently scheduled to the appropriate servers by integrating complexity with an adaptive resource-aware optimization algorithm. For input tasks, JAVP can dynamically and intelligently select the most appropriate server. The evaluation results on public datasets show that JAVP can improve the through-put by more than 70% compared to traditional cloud-only solutions while meeting accuracy requirements. And JAVP can improve the accuracy by 3%-5% and reduce delay and energy consumption by 16%-50% compared to state-of-the-art edge-cloud solutions.
