min_imagemin_imageMinImageMinImagemin_image（算子）

名称

min_imagemin_imageMinImageMinImagemin_image — 逐像素计算两个图像的最小值。

签名

min_image(Image1, Image2 : ImageMin : : )

描述

算子 min_imagemin_imageMinImageMinImageMinImagemin_image determines the minimum (pixel by pixel) of the images Image1Image1Image1Image1image1image_1 and Image2Image2Image2Image2image2image_2. The result is stored in the image ImageMinImageMinImageMinImageMinimageMinimage_min. The resulting image has the same pixel type as the input image. If several (pairs of) images are processed in one call, every i-th image from Image1Image1Image1Image1image1image_1 is compared to the i-th image from Image2Image2Image2Image2image2image_2. Thus the number of images in both input parameters must be the same. An output image is generated for every input pair.

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

执行信息

支持 OpenCL 计算设备。
多线程类型：可重入（与非独占算子并行运行）。
多线程作用域：全局（可从任何线程调用）。
在元组级别上自动并行化。

参数

Image1Image1Image1Image1image1image_1 (输入对象) (multichannel-)image(-array) → object (byte* / int1* / int2* / uint2* / int4* / int8 / real* / direction* / cyclic*) *允许用于计算设备

图像 1。

Image2Image2Image2Image2image2image_2 (输入对象) (multichannel-)image(-array) → object (byte* / int1* / int2* / uint2* / int4* / int8 / real* / direction* / cyclic*) *允许用于计算设备

图像 2。

ImageMinImageMinImageMinImageMinimageMinimage_min (输出对象) (multichannel-)image(-array) → object (byte / int1 / int2 / uint2 / int4 / int8 / real / direction / cyclic)

Result image(s) by the minimization.

结果

如果参数值正确，算子 min_imagemin_imageMinImageMinImageMinImagemin_image 返回值 2 (H_MSG_TRUE)。当输入为空（无可用输入图像）时，可设置行为通过算子 set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)。如有必要，则抛出异常。
