    node-red-contrib-biometricvision

    Node Red node for determining if a person matches between two digital images returning probability factors on key metric using api's from Biometric Vision.

    Features:

    • Auto resize if image payload size too large
    • Can reduce max size for performance to minimise latency
    • Cache reference image for performance for repeated calls to reference image
    • Save image for reference image so id reference image for check

    Below is the test flow that can be found showing the various features. Note, images need to be copied from the repro's test folder to required location and the fetch file node updated.

    Test Flow


    face compare

    Defines a face comparing node using Biometric Vision service. Can compare two images or store an image as a reference point. Images are cached for hour to minimise overhead on many compares against single image. Auto resize of images to below 1 MB if image too large for Biometric Vision call.

    Token is obtained from Biometric Vision site. Has free usage for small amount of testing.

    Topics can be set to control

    cache/< identifier > Put image in payload into cache

    compare/< identifier > Compare image payload with image associated with identifier

    save/< identifier > Put image in payload into cache and persist in named file system directory

    clearCache Clear the cache

    otherwise compares payload.image1 to payload.image2
