Transformation

ImageDataGenerator property

• width_shift_range : move in horizontal range

• height_shift_range : move in vertical range

• rotation_range : rotation within the angular range

• brightness_range

• zoom_range : zoom in/out of image in range

• horizontal_flip : flip image horizontally

• vertical_flip : flip image vertically

• rescale

• preprocessing_function

 

 

Rescale시 주의사항

transformation은 test셋에서는 할 필요가 없지만 rescale은 train셋과 test셋 둘 다 해주어야 한다.
