TABLE 1.

The setting of hyper-parameters in Random-Cutout in this research.

	Definition of parameters	Mathematical definition
I	The initial probability value of each pixel point is 0.001. When wheat ears exist at this pixel point, the probability value of the pixel point is the initial value plus the number of wheat ears multiplied by 0.003	Ii = 0.0010.003×ni
N	1/4 of the number of wheat ears in the image	N = Ntotal/4
H	Random number between one quarter of the minimum length and one quarter of the maximum length of the wheat ear in the image	$\forall H\in \bigcup (\frac{1}{4}\times H_{min},\frac{1}{4}\times H_{max})$
W	Random number between one quarter of the minimum width and one quarter of the maximum width of the wheat ears in the image	$\forall W\in \bigcup (\frac{1}{4}\times W_{min},\frac{1}{4}\times W_{max})$
