Description

The operator min_imagemin_imagemin_imageMinImageMinImage determines the minimum (pixel by pixel) of the images Image1Image1Image1Image1image1 and Image2Image2Image2Image2image2. The result is stored in the image ImageMinImageMinImageMinImageMinimageMin. 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 Image1Image1Image1Image1image1 is compared to the i-th image from Image2Image2Image2Image2image2. Thus the number of images in both input parameters must be the same. An output image is generated for every input pair.

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

Parameters

Image1Image1Image1Image1image1 (input_object)  (multichannel-)image(-array) → objectHImageHImageHImageXHobject (byte* / int1* / int2* / uint2* / int4* / int8 / real* / direction* / cyclic*) *allowed for compute devices

Image(s) 1.

Image2Image2Image2Image2image2 (input_object)  (multichannel-)image(-array) → objectHImageHImageHImageXHobject (byte* / int1* / int2* / uint2* / int4* / int8 / real* / direction* / cyclic*) *allowed for compute devices

Image(s) 2.

ImageMinImageMinImageMinImageMinimageMin (output_object)  (multichannel-)image(-array) → objectHImageHImageHImageXHobject * (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_imagemin_imageMinImageMinImage 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>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>) If necessary an exception is raised.
