基类：Mapper

Mapper to resize videos resolution. We leave the super resolution with deep learning for future works.

__init__(min_width: int = 1, max_width: int = 9223372036854775807, min_height: int = 1, max_height: int = 9223372036854775807, force_original_aspect_ratio: str = 'disable', force_divisible_by: Annotated[int, Gt(gt=0)] = 2, *args, **kwargs)[源代码]#

Initialization method.

参数:

  • min_width -- Videos with width less than 'min_width' will be mapped to videos with equal or bigger width.

  • max_width -- Videos with width more than 'max_width' will be mapped to videos with equal of smaller width.

  • min_height -- Videos with height less than 'min_height' will be mapped to videos with equal or bigger height.

  • max_height -- Videos with height more than 'max_height' will be mapped to videos with equal or smaller height.

  • force_original_aspect_ratio -- Enable decreasing or increasing output video width or height if necessary to keep the original aspect ratio, including ['disable', 'decrease', 'increase'].

  • force_divisible_by -- Ensures that both the output dimensions, width and height, are divisible by the given integer when used together with force_original_aspect_ratio, must be a positive even number.

  • args -- extra args

  • kwargs -- extra args

process_single(sample, context=False)[源代码]#

For sample level, sample --> sample

参数:

sample -- sample to process

返回:

processed sample
