Short description🔗

exp_imageExpImageExpImageexp_imageexp_image — Calculate the exponentiation of an image.

Description🔗

exp_imageExpImage calculates the exponentiation to the base BasebaseValbase of an input image Imageimageimage and stores the result in the image ExpImageexpImageexp_image. If Imageimageimage contains gray values that would overflow the range of ExpImageexpImageexp_image, e.g., \(> 88.722839\) for \(\textrm{Base} = '\textit{e}'\), the corresponding gray values in ExpImageexpImageexp_image are set to the largest value representable in ExpImageexpImageexp_image (i.e., \(3.4028235 \times 10^{38}\)).

Attention🔗

exp_imageExpImage 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🔗

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.
