1. A computer-implemented method for extracting structured data from an image, comprising:
receiving a captured image depicting a readable item;
at a hardware processing device, extracting a plurality of anchor points from the captured image;
at the hardware processing device, generating an anchor point arrangement specifying locations of anchor points within the captured image;
at the hardware processing device, generating a plurality of templates, wherein each template specifies a plurality of anchor points and field read locations;
at the hardware processing device, automatically selecting one of the plurality of templates, based on a relative degree of similarity between the templates and the anchor point arrangement;
at the hardware processing device, automatically generating a transform for mapping points in the selected template to corresponding points in the captured image; and
at the hardware processing device, applying the generated transform to extract structured data from the captured image;
wherein generating the plurality of templates comprises, for each template:
displaying an image on a display screen, the displayed image comprising a plurality of fields at locations within the image;
receiving first input from a human user identifying read locations for the fields in the displayed image;
receiving second input from the human user specifying information about the identified read locations; and
at a storage device, storing the identified read locations and the information as the template.
