Abstract: A method of capturing and providing, with a mobile device, images of retail products for analysis by a remote image analysis engine applying one or more machine learning models, may include, at a mobile device comprising a processor, a memory, a display, and an integrated camera, prompting a user to capture an image of an array of physical items, capturing the image with the integrated camera, and sending the captured image to a remote server. The method may further include receiving an image annotation data set defining an array of segments, each segment corresponding to a physical item in the array of physical items and having an associated product information, a given associated product information determined using a trained product model that identifies a product identifier based on a portion of the image that corresponds to a given segment of the image.
