Claim 4:
5. The method of claim 1, wherein the assigning the second set of template predictions includes:
partitioning, by the processor, an instance of the digital image into a plurality of partitions;
generating, by the processor, the second plurality of keypoints based on a partition of the plurality of partitions,
wherein the keypoint of the second plurality of keypoints includes a multidimensional descriptor vector that represents an image gradient at a location of the digital image associated with the keypoint of the second plurality of keypoints;
comparing, by the processor, the multi-dimensional descriptor vector that represents the image gradient to a plurality of clusters of multi-dimensional descriptor vectors associated with keypoints in previously classified example digital images;
mapping, by the processor, the multi-dimensional descriptor vector that represents the image gradient to a nearest cluster of the plurality of clusters, based on the comparison;
generating, by the processor, the histogram that represents a histogram of most frequently mapped clusters; and
assigning a template prediction to the partition of the plurality of partitions based on a most frequently mapped cluster of the histogram.
