Howe variation of White stimulus, Domijan (2015) Fig 11C

Parameters:

  • visual_size (Sequence[Number, Number], Number, or None) – visual size [height, width] in degrees, default: (10, 10)

  • ppd (Sequence[Number, Number], Number, or None) – pixels per degree [vertical, horizontal], default: 10

  • shape (Sequence[Number, Number], Number, or None) – shape [height, width] in pixels, default: (100, 100)

  • pad (bool) – If True, include original padding (default: False)

Returns:

dict with the stimulus (key: “img”) and target mask (key: “target_mask”) and additional keys containing stimulus parameters

Return type:

dict[str, Any]
