region_to_meanregion_to_meanRegionToMeanRegionToMean (Operator)

Name

region_to_meanregion_to_meanRegionToMeanRegionToMean — Paint regions with their average gray value.

Signature

region_to_mean(Regions, Image : ImageMean : : )

region_to_meanregion_to_meanRegionToMeanRegionToMeanRegionToMean returns an image in which the regions RegionsRegionsRegionsRegionsregions are painted with their average gray value based on the image ImageImageImageImageimage. This operator is mainly intended to visualize segmentation results.

Execution Information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Automatically parallelized on channel level.

Parameters

RegionsRegionsRegionsRegionsregions (input_object) region(-array) → object

Input regions.

ImageImageImageImageimage (input_object) (multichannel-)image → object (byte / uint2)

original gray-value image.

ImageMeanImageMeanImageMeanImageMeanimageMean (output_object) image → object (byte / uint2)

Result image with painted regions.

Example (HDevelop)

read_image(Image,'fabrik')
regiongrowing(Image,Regions,3,3,6,100)
region_to_mean(Regions,Image,Disp)
dev_display(Disp)
dev_set_draw('margin')
dev_display(Regions)

Example (C)

read_image(&Image,"fabrik");
regiongrowing(Image,&Regions,3,3,6,100);
region_to_mean(Regions,Image,&Disp);
disp_image(Disp,WindowHandle);
set_draw(WindowHandle,"margin");
disp_region(Regions,WindowHandle);

Example (HDevelop)

read_image(Image,'fabrik')
regiongrowing(Image,Regions,3,3,6,100)
region_to_mean(Regions,Image,Disp)
dev_display(Disp)
dev_set_draw('margin')
dev_display(Regions)

Example (HDevelop)

read_image(Image,'fabrik')
regiongrowing(Image,Regions,3,3,6,100)
region_to_mean(Regions,Image,Disp)
dev_display(Disp)
dev_set_draw('margin')
dev_display(Regions)

Example (HDevelop)

read_image(Image,'fabrik')
regiongrowing(Image,Regions,3,3,6,100)
region_to_mean(Regions,Image,Disp)
dev_display(Disp)
dev_set_draw('margin')
dev_display(Regions)

Result

region_to_meanregion_to_meanRegionToMeanRegionToMeanRegionToMean returns 2 (H_MSG_TRUE) if all parameters are correct. If the input is empty the behavior can be set via 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>). If necessary, an exception is raised.
