Corrugated Mondrian

Parameters:

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

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

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

  • depths (Sequence[Number, ... ], Number, or None (default)) – depth of Mondrian parallelograms per row

  • intensities (nested tuples) – intensities of mondrians; as many tuples as there are rows and as many numbers in each tuple as there are columns

  • target_indices (nested tuples) – indices of targets; as many tuples as there are targets with (y, x) indices

  • intensity_background (float) – intensity value for background

  • intensity_target (float) – target intensity. If None, use values defined in intensities

Returns:

dict with the stimulus (key: “img”), mask with integer index for each target (key: “target_mask”), and additional keys containing stimulus parameters

Return type:

dict[str, Any]
