Description

ImageInputGroup — still-image source NodeGroup that emits a video-shaped stream.

Bundles a file source, an image decoder (JPEG, PNG, or auto-detected), and an imagefreeze-style stage that promotes the single still frame into a continuous video stream at a chosen frame rate. Typical placement: very first NodeGroup in a Session that wants to test or demo a vision pipeline against a single image instead of a live source.
