mmcls.datasets.pipelines.Shear

class mmcls.datasets.pipelines.Shear(magnitude, pad_val=128, prob=0.5, direction='horizontal', random_negative_prob=0.5, interpolation='bicubic')

Shear images.

参数

• magnitude (int | float) – The magnitude used for shear.

• pad_val (int, Sequence[int]) – Pixel pad_val value for constant fill. If a sequence of length 3, it is used to pad_val R, G, B channels respectively. Defaults to 128.

• prob (float) – The probability for performing Shear therefore should be in range [0, 1]. Defaults to 0.5.

• direction (str) – The shearing direction. Options are ‘horizontal’ and ‘vertical’. Defaults to ‘horizontal’.

• random_negative_prob (float) – The probability that turns the magnitude negative, which should be in range [0,1]. Defaults to 0.5.

• interpolation (str) – Interpolation method. Options are ‘nearest’, ‘bilinear’, ‘bicubic’, ‘area’, ‘lanczos’. Defaults to ‘bicubic’.
