Enroll a shelf: the products read off its crops become the store's catalog.
|
|
|
|
This is the onboarding flow a real store would go through once - detect the facings,
|
|
name the products, and keep their crops as the gallery that recognition matches
|
|
against. The two demo shelves were built with it; the product lists live in this file
|
|
because reading a contact sheet is a human step.
