名称

invert_imageinvert_imageInvertImageInvertImageinvert_image — 反转图像。

签名

invert_image(Image : ImageInvert : : )

描述

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