Abstract: A computer, including a processor and a memory, the memory including instructions to be executed by the processor to acquire a first image by illuminating a first object with a first light beam, segment the first image of the first object to determine regions that correspond to a first surface material and determine a first measure of pixel values in regions of the first image that correspond to the first surface material. The instructions include further instructions to perform a comparison of the first measure of pixel values to a second measure of pixel values determined from a second image of a second object, wherein the second image is previously acquired by illuminating the second object with a second light beam and when the comparison determines that the first measure is equal to the second measure of pixel values within a tolerance, determine that the first object and the second object are a same object.

Abstract: A debris collection device for sweeping up residual grain in a bin includes a plate, a plurality of bristles, and a stick. The plate is elongated rectangularly shaped and comprises a first section, which is planar, and second section, which is curved. The bristles are coupled to and extend from a lower face of the plate. The stick is coupled to and extends from an upper face of the plate. The stick is configured to be grasped in hands of a user, positioning the user to urge the bristles that are positioned on the first section across a first surface with the bristles positioned on the second section configured to contact a second surface that is positioned substantially perpendicular to the first surface to collect debris that is positioned on the first surface.
