exp_imageexp_imageExpImageExpImageexp_image (Operator)

Name

exp_imageexp_imageExpImageExpImageexp_image — Calculate the exponentiation of an image.

Signature

exp_image(Image : ExpImage : Base : )

Description

exp_imageexp_imageExpImageExpImageexp_image calculates the exponentiation to the base BaseBaseBasebaseValbase of an input image ImageImageImageimageimage and stores the result in the image ExpImageExpImageExpImageexpImageexp_image. If ImageImageImageimageimage contains gray values that would overflow the range of ExpImageExpImageExpImageexpImageexp_image, e.g., > 88.722839 for BaseBaseBasebaseValbase = 'e'"e""e""e""e", the corresponding gray values in ExpImageExpImageExpImageexpImageexp_image are set to the largest value representable in ExpImageExpImageExpImageexpImageexp_image (i.e., ).

Attention

exp_imageexp_imageExpImageExpImageexp_image can be executed on an OpenCL device for byte, int1, int2, uint2, int4, and real images. Note that the results of the OpenCL code may vary from the results produced by the CPU.

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

ImageImageImageimageimage (input_object) (multichannel-)image(-array) → object (byte* / int1* / uint2* / int2* / int4* / int8 / real*) *allowed for compute devices

Input image.

ExpImageExpImageExpImageexpImageexp_image (output_object) (multichannel-)image(-array) → object (real)

Output image.

BaseBaseBasebaseValbase (input_control) number → (string / integer / real)
