max_imagemax_imagemax_imageMaxImageMaxImage (Operator)

Name

max_imagemax_imagemax_imageMaxImageMaxImage — Calculate the maximum of two images pixel by pixel.

Signature

Description

max_imagemax_imagemax_imageMaxImageMaxImage calculates the maximum of the images Image1Image1Image1Image1image1 and Image2Image2Image2Image2image2 (pixel by pixel). The result is stored in the image ImageMaxImageMaxImageMaxImageMaximageMax. 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.

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

Attention

The two input images must be of the same type and size.

Parallelization

• 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

read_image(Image1,'monkey')
read_image(Image2,'fabrik')
max_image(Image1,Image2,Max)
disp_image(Max,WindowHandle)

read_image(&Image1,"monkey");
read_image(&Image2,"fabrik");
max_image(Image1,Image2,&Max);
disp_image(Max,WindowHandle);

read_image(Image1,'monkey')
read_image(Image2,'fabrik')
max_image(Image1,Image2,Max)
disp_image(Max,WindowHandle)

read_image(Image1,'monkey')
read_image(Image2,'fabrik')
max_image(Image1,Image2,Max)
disp_image(Max,WindowHandle)

read_image(Image1,'monkey')
read_image(Image2,'fabrik')
max_image(Image1,Image2,Max)
disp_image(Max,WindowHandle)

Result

If the parameter values are correct the operator max_imagemax_imagemax_imageMaxImageMaxImage 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.
