1. A method for determining moisture content of corn, the method comprising: processing a captured image of an ear of corn using a threshold value to create a segmented binary image comprising a first plurality of blobs; generating a luminance intensity profile across a region of the captured image containing at least one blob in the first plurality of blobs; determining, with reference to the luminance intensity profile, at least one characteristic of a plurality of corn kernels represented by the first plurality of blobs, the at least one characteristic including the location of the boundary of the at least one corn kernel; and estimating a moisture value for the ear of corn based on the at least one characteristic of the plurality of corn kernels.
