1. A method for using image processing in screening maize to determine the maize more likely to exhibit stress tolerance and/or those less likely to exhibit stress tolerance, the method comprising:
- acquiring images of kernels of maize;
processing the images of the kernels of maize;
extracting from the images of the kernels of maize estimates of a phenotype associated with stress tolerance for each of the kernels of maize;
relating the estimate of the phenotype from a first subset of the kernels of maize to estimates from a second subset of the kernels of maize;
determining variation between the first subset and the second subset;
selecting for kernels with stress tolerance relative to other kernels.

Abstract
A method of evaluating one or more kernels of an ear of maize using digital imagery includes acquiring a digital image of the one or more kernels of the ear of maize, processing the digital image to estimate at least one physical property of the one or more kernels of the ear of maize from the digital image, and evaluating the at least one kernel of maize using the estimate of the at least one physical property of the at least one kernel of maize.

8. A method for using image processing in screening maize to determine the maize more likely to exhibit stress tolerance and/or those less likely to exhibit stress tolerance, the method comprising:
-
acquiring images of ears of maize; processing the images of the ears of maize; extracting from the images of the ears of maize estimates of an ear component phenotype associated with stress tolerance for each of the ears of maize; relating the estimate of the ear component phenotype from a first subset of the ears of maize to estimates from a second subset of the ears of maize; determining variation between the first subset and the second subset; selecting for ears with stress tolerance relative to other ears. - View Dependent Claims (9, 10, 11, 12, 13, 14, 27)

15. A method of counting kernels on an ear of maize, comprising:
-
providing a digital image of the ear of maize; extracting a filled kernel area from the ear of maize using a predetermined color palette; applying a filter to the digital image to enhance the center of each kernel of the ear of maize; counting the number of kernels on the ear of maize represented in the digital image; providing to a user an output related to the number of kernels on the ear. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 28)

25. A system for evaluating ears of maize, comprising:
-
a picker adapted for picking ears of maize; an image sensor adapted to image the ears of maize after picking to provide digital imagery of the ears of maize; an image processing component adapted to process the digital imagery to determine physical properties of the ear of maize; a sheller adapted for shelling the ears of maize; a conveyor to convey the ears of maize from the picker to the sheller, wherein the physical properties include number of kernels on each of the ears of maize, and wherein the image processing component is adapted for extracting a filled kernel area from the ear of maize using a predetermined color palette, applying a filter to the digital image to enhance a center of each kernel of the ear of maize, and counting number of kernels on the ear of maize represented in the digital image.
