In order to win this inevitable battle and fight against COVID-19, we must work together and share our experiences around the world. Join us in the fight against the outbreak through the Global MediXchange for Combating COVID-19 (GMCC) program. Apply now at https://covid-19.alibabacloud.com/

By Alibaba Cloud Serverless.

The coronavirus disease (COVID-19) pandemic broke out in China, spreading rapidly before and during Chinese New Year, 2020. The detection of mask-wearing in public places is key for epidemic prevention and control.

To cope with the pandemic, the Alibaba Cloud Vision Intelligent Application Programming Interface Platform quickly launched the mask detection API service based on vision AI analysis. This service allows developers to build a system quickly to check whether people have their masks on without telling their personal identity for privacy protection. The service is expected to enhance the efficiency of community access management during the virus outbreak.

In addition to mask detection for a single face, the platform uses Alibaba Cloud services, such as Function Compute, Serverless Workflow, Object Storage Service (OSS), and Resource Orchestration Service (ROS), and its self-developed algorithms to integrate multiple APIs into new capabilities. For example, the face detection API and mask detection API are used to implement mask detection for multiple people at the same time. Such a new capability allows mask detection for multiple faces in a single image without identifying those persons for privacy protection.

What are ROS, Serverless Workflow, and Function Compute?

  • ROS is a simple, easy-to-use service for cloud computing resource management and automated O&M. You can use ROS templates to describe the dependencies between cloud computing resources and their configurations. Then, ROS can automatically create and configure all resources for automatic deployment and O&M according to the templates.
  • Serverless Workflow is a fully-managed cloud service that coordinates multiple distributed tasks. You can orchestrate distributed tasks in sequence, branch, or parallel mode. This service reliably coordinates task execution according to the preset steps, tracks the status change of each task, and runs the user-defined retry logic when necessary.
  • Function Compute is an event-driven and fully-managed computing service. With Function Compute, you only need to compile and upload code, without purchasing or managing infrastructures, such as servers. Function Compute prepares computing resources and runs tasks elastically and reliably. In addition, it provides features such as performance monitoring and alerts.

With the preceding services, after you upload images to OSS, the image processing process written with Serverless Workflow is automatically triggered. In this process, the number of faces in an image is first spot. If the image contains only one face, mask recognition will be performed. If the image contains multiple faces, mask recognition will be performed individually for each face.

Function Compute calls different AI capabilities based on different scenarios. This example shows that Serverless Workflows can easily combine vision intelligent APIs and Function Compute to cope with complex scenarios. You can visit the ROS page to learn more and experience its whole set of capabilities.

To help prevent and control the pandemic and improve the effectiveness of epidemic monitoring, the face mask detection API service is available free of charge to enterprises and individual developers. Enterprises and individual developers can use APIs for standardized interworking. This service can be quickly applied in communities, enterprise buildings, medical institutions, and other public places for real-time mask wearing detection to assist management personnel with on-site management.

The Alibaba Cloud Vision Intelligent Application Programming Interface Platform is a comprehensive vision AI platform that helps enterprises and developers quickly establish vision AI-based application capabilities. Based on Alibaba’s practical experience in visual intelligence, the platform provides easy-to-use, inclusive visually intelligent API services to users who develop and apply the visual intelligence technology. In addition, the platform provides more than 50 API services based on vision AI for free, including text recognition, product understanding. Enterprises and individual developers are welcome to call these services to create more applications, and contribute to the fight against the pandemic.

While continuing to wage war against the worldwide outbreak, Alibaba Cloud will play its part and will do all it can to help others in their battles with the coronavirus. Learn how we can support your business continuity at https://www.alibabacloud.com/campaign/fight-coronavirus-covid-19
