Augmentation
Utility func to easily create a list of flip, rotate, zoom, warp, lighting transforms.
aug_transforms( mult = 1, do_flip = TRUE, flip_vert = FALSE, max_rotate = 10, min_zoom = 1, max_zoom = 1.1, max_lighting = 0.2, max_warp = 0.2, p_affine = 0.75, p_lighting = 0.75, xtra_tfms = NULL, size = NULL, mode = "bilinear", pad_mode = "reflection", align_corners = TRUE, batch = FALSE, min_scale = 1 )
