class mindspore.dataset.vision.Erase(top, left, height, width, value=0, inplace=False)

Erase the input image with given value.

Parameters

• top (int) – Vertical ordinate of the upper left corner of erased region.

• left (int) – Horizontal ordinate of the upper left corner of erased region.

• height (int) – Height of erased region.

• width (int) – Width of erased region.

• value (Union[int, Sequence[int, int, int]], optional) – Pixel value used to pad the erased area. Default: 0. If int is provided, it will be used for all RGB channels. If Sequence[int, int, int] is provided, it will be used for R, G, B channels respectively.

• inplace (bool, optional) – Whether to apply erasing inplace. Default: False.
