The Performance Research of the Data Augmentation Method for Image Classification

Table 2

The super-parameters of the augmentation method in our experiments.

Augmentation Method Name	Description
Flip	Random horizontal and vertical reversal
Shift	P [0, 0.1]. p is the fraction of total width or height range in random vertical or horizontal shift
Rotation	P [0, 90]. p is the degree range angle for random rotation
Color	P [0.7, 1.3] p is the enhancement factor, 0.0 return black and white image, 1.0 give the origin image
Contrast	P [0.7, 1.3] 1.0 return the original image, factor p of 0.1 gives the solid grey image
