invert_imageinvert_imageInvertImageInvertImage (Operator)

Name

invert_imageinvert_imageInvertImageInvertImage — Invert an image.

Signature

Description

The operator invert_imageinvert_imageInvertImageInvertImageInvertImage inverts the gray values of an image. For images of the 'byte' and 'cyclic' type the result is calculated as: g' = 255 - g Images of the 'direction' type are transformed by g' = (g + 90) modulo 180 In the case of signed types the values are negated. The resulting image has the same pixel type as the input image.

Several images can be processed in one call. An output image is generated for every input image.

invert_imageinvert_imageInvertImageInvertImageInvertImage can be executed on an OpenCL device for byte, direction, cyclic, int1, int2, uint2, int4, and real images.

Execution Information

• Supports OpenCL compute devices.
• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Automatically parallelized on tuple level.
• Automatically parallelized on channel level.
• Automatically parallelized on domain level.

Parameters
