Classification: CPC G | IPC G

Claim 0:
1. A method comprising, at a computer system comprising a processor and a computer-readable medium:
receiving an image depicting a machine-readable label;
generating a set of boundary points on the image by applying a first machine-learning model to the image, wherein the first machine-learning model is trained to identify boundary points on an image;
generating a set of initial subregions of the image based on the boundary points, wherein each initial subregion of the set of initial subregions comprises a plurality of corners at a subset of the set of boundary points;
generating a transformation matrix for each initial subregion of the set of initial subregions, wherein each transformation matrix comprises a set of values for transforming a corresponding initial subregion into a standardized subregion;
generating a set of standardized subregions of the image by applying each transformation matrix to a corresponding initial subregion of the set of initial subregions;
concatenating the set of standardized subregions into a modified image; and
identifying an item identifier encoded in the machine-readable label by applying a label decoding model to the modified image, wherein the label decoding model is trained to predict item identifiers based on images of machine-readable labels.
