Why each option
The app identifies the coordinates of products in an image, which is a task best suited for object detection.
Azure AI Custom Vision classification identifies what is in an image as a whole, rather than identifying and locating multiple specific objects within it.
Azure AI Custom Vision object detection allows you to train a custom model to identify objects within images and return their bounding box coordinates and labels. This is precisely what's needed to find the specific location (coordinates) of products on a supermarket shelf.
Azure AI Computer Vision Read is designed for extracting text content from images or documents, not for identifying non-textual objects.
Azure AI Computer Vision OCR specifically focuses on extracting printed or handwritten text from images and documents.
