ROI Intelligent Recognition

Last updated: 2024-05-29 10:00:35
    ROI Intelligent Recognition technology can detect the coordinate information of key elements (XML) such as faces, game characters, and anchors in videos in real time, and transmit the Region of Interest (ROI) information along with the video encoding to the playback terminal. By combining the player with ROI information, features like intelligent on-screen comment anti-shading and background blur can be achieved. This article will show you how to create, modify, and delete ROI Intelligent Recognition templates through the console.

    Notes

    A template takes effect about 5-10 minutes after it is created.
    To use the ROI Intelligent Recognition feature, include the streaming parameter roirecognition=ROI configuration name in the streaming address. The player can then access the ROI information in the live stream and process it to achieve effects such as intelligent on-screen comment anti-shading, background blur. For comprehensive usage of the ROI feature and player processing details, see ROI Intelligent Recognition Feature Practice. An example of the streaming address is:
    rtmp://domain/AppName/StreamName?roirecognition=ROI Configuration Name
    Region of Interest (ROI) feature is part of the Paid Value-Added Service. Using this feature incurs live transcoding fees and Media Processing Service (MPS) content intelligent recognition fees. For specific billing rules, refer to the billing documentation.

    Prerequisites

    Activated Tencent CSS service.

    Creating a ROI Configuration Template

    1. Log in to CSS Console, select Laboratory > ROI Intelligent Recognition.

    2. Click Authorize Now to enter the CAM role management page.
    
    
    
    3. On the role management page, click Grant to complete the identity verification and finalize the Media Processing Service authorization, enabling normal use of the Media Processing Service.
    
    
    
    4. After successful authorization, check the service agreement and click Start, and the system will automatically activate the MPS product and open the Intelligent Streaming Media Processing management page.

    Training Model
    Default is General. Supported training models include: Honor of Kings, NBA2K Game, and Live Shows.
    General: capable of recognizing common areas of human eye focus in different environments.
    Honor of Kings: capable of recognizing hero roles and zones in different environments within the Honor of Kings game.
