Calculate the absolute value (modulus) of an image.
The operator abs_image calculates the absolute gray values of images of any type and stores the result in ImageAbs. The power spectrum of complex images is calculated as a 'real' image. The operator abs_image generates a logical copy of unsigned images.

Image (input_object) |
(multichannel-)image(-array) -> object : int1 / int2 / int4 / real / complex |
| Image(s) for which the absolute gray values are to be calculated. | |

ImageAbs (output_object) |
(multichannel-)image(-array) -> object : int1 / int2 / int4 / real |
| Result image(s). | |

The operator abs_image returns the value 2 (H_MSG_TRUE). The behavior in case of empty input (no input images available) is set via the operator set_system(::'no_object_result',<Result>:)
abs_image is reentrant and automatically parallelized (on tuple level, channel level, domain level).
