Claim 13:
14. A method comprising:
receiving, by one or more processors and from a camera, an image of coffee grinds produced by a coffee grinder;
analyzing, by the one or more processors, the image using one or more image processing techniques to determine a representative grind size for the coffee grinds;
determining, by the one or more processors, a grind setting of the coffee grinder;
selecting, by the one or more processors, a predefined reference size based on the grind setting of the coffee grinder, the predefined reference size being selected from among a plurality of predefined reference sizes corresponding to different grind settings of the coffee grinder;
determining, by the one or more processors, whether the representative grind size of the coffee grinds deviates from the predefined reference size by at least a threshold amount; and
outputting, by the one or more processors, an instruction indicating how to calibrate the coffee grinder to more closely adhere to the predefined reference size, in response to determining that the representative grind size of the coffee grinds deviates from the predefined reference size by at least the threshold amount.
