Table 10. Analysis results between original images and grayscale images in 448 pixel

Model	Original Image	Top1	Top2	Top3	Top4	Top5
VGG-16 in 448 pixel
	X96	X96_90	X55_90	X64_90	X127	X64
		1(0.99997)	0.999(0.99932)	0.999(0.99928)	0.999(0.99925)	0.999(0.99923)
	X100	X180	X149	X102	X100_90	X180_90
		1(0.99980)	1(0.99971)	1(0.99970)	1(0.99967)	1(0.99965)

a: In imgaes “Xnumber_90”, 90 means that the image is rotated 90 degrees from the original
b: Correlation is a similarity value(the similarity rate is 100% as it approaches 1) and it is rounded to the fourth decimal place
