Details and OptionsDetails and Options

  • RandomImage gives an image where pixel values are drawn from a specified distribution. The pixel values are not correlated spatially.

  • RandomImage by default gives an image of a real type.
  • RandomImage[] is equivalent to RandomImage[1,{150,150}].
  • RandomImage[] is equivalent to RandomImage[,{150,150}].
  • The size specification can be one of the following:
  • {width,height}2D image size specification
    {width,depth,height}3D image size specification
  • The following options are supported:
  • ColorSpaceAutomaticcolor space of the output image
