Random affine transformation of the image keeping center invariant
Random affine transformation of the image keeping center invariant
transform_random_affine( img, degrees, translate = NULL, scale = NULL, shear = NULL, resample = 0, fillcolor = 0 )
img |
A |
degrees |
(sequence or float or int): Range of degrees to select from. If degrees is a number instead of sequence like (min, max), the range of degrees will be (-degrees, +degrees). |
translate |
(tuple, optional): tuple of maximum absolute fraction for horizontal and vertical translations. For example translate=(a, b), then horizontal shift is randomly sampled in the range -img_width * a < dx < img_width * a and vertical shift is randomly sampled in the range -img_height * b < dy < img_height * b. Will not translate by default. |
scale |
(tuple, optional): scaling factor interval, e.g (a, b), then scale is randomly sampled from the range a <= scale <= b. Will keep original scale by default. |
shear |
(sequence or float or int, optional): Range of degrees to select
from. If shear is a number, a shear parallel to the x axis in the range
(-shear, +shear) will be applied. Else if shear is a tuple or list of 2
values a shear parallel to the x axis in the range |
resample |
(int, optional): An optional resampling filter. |
fillcolor |
(tuple or int): Optional fill color (Tuple for RGB Image and int for grayscale) for the area outside the transform in the output image (Pillow>=5.0.0). This option is not supported for Tensor input. Fill value for the area outside the transform in the output image is always 0. |
