RandomShadow

Description

Simulates shadows for the image by reducing the brightness of the image in shadow regions.

    Args:
        shadow_roi (tuple): region of the image where shadows
            will appear (x_min, y_min, x_max, y_max). All values should be in range [0, 1].
        num_shadows_limit (tuple): Lower and upper limits for the possible number of shadows.
            Default: (1, 2).
        shadow_dimension (int): number of edges in the shadow polygons. Default: 5.
        shadow_intensity_range (tuple): Range for the shadow intensity.
            Should be two float values between 0 and 1. Default: (0.5, 0.5).
        p (float): probability of applying the transform. Default: 0.5.

    Targets:
        image

    Image types:
        uint8, float32
