min_imagemin_imageMinImageMinImagemin_image (Operator)

Name

min_imagemin_imageMinImageMinImagemin_image — Calculate the minimum of two images pixel by pixel.

Signature

min_image(Image1, Image2 : ImageMin : : )

Description

The operator 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.

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

Image1Image1Image1Image1image1image_1 (input_object) (multichannel-)image(-array) → object (byte* / int1* / int2* / uint2* / int4* / int8 / real* / direction* / cyclic*) *allowed for compute devices

Image(s) 1.

Image2Image2Image2Image2image2image_2 (input_object) (multichannel-)image(-array) → object (byte* / int1* / int2* / uint2* / int4* / int8 / real* / direction* / cyclic*) *allowed for compute devices

Image(s) 2.

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

Result image(s) by the minimization.

Result

If the parameter values are correct the operator min_imagemin_imageMinImageMinImageMinImagemin_image returns the value 2 (H_MSG_TRUE). The behavior in case of empty input (no input images available) is set via the operator 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>) If necessary an exception is raised.
