exp_imageexp_imageExpImageExpImageexp_image (算子名称)

名称

exp_imageexp_imageExpImageExpImageexp_image — Calculate the exponentiation of an image.

参数签名

exp_image(Image : ExpImage : Base : )

描述

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

注意

exp_imageexp_imageExpImageExpImageExpImageexp_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.
