Finding Four-Leaf Clovers
Goal: to create a reliable benchmark for fine-grained object localization problems
Other fine-grained object localization problems:
Cancer diagnosis (Medicine)
Identifying cells in mitosis (Medicine)
Detecting infected crops (Biology)
Finding a specific person in a crowd (Industry)

The Four-Leaf Clover Dataset
FLC dataset statistics. 4-leaf clover pixels and 4-leaf clover boundary pixels refer to the rate of the total of positive pixels over the total of pixels in the FLC dataset.

Comparison to Other Datasets
Comparison of FLC to major visual recognition datasets. Club (♣) indicates that a dataset allows to study a recognition problem at a fine-grained level, triangle (Δ) indicates that the version of
the problem is not fine-grained, and (×) indicates that a dataset does not allow to study a problem.
