mean_nmean_nMeanNmean_nMeanNMeanN (Operator)

Name

mean_nmean_nMeanNmean_nMeanNMeanN — Average gray values over several channels.

The operator mean_nmean_nMeanNmean_nMeanNMeanN generates the pixel-by-pixel mean value of all channels . For each coordinate point the sum of all gray values at this coordinate is calculated. The result is the mean of the gray values (sum divided by the number of channels). The output image has one channel.

Parallelization

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 domain level.

Parameters

ImageImageImageImageImageimage (input_object) (multichannel-)image(-array) → object (byte / int2 / uint2 / int4 / real)

Multichannel gray image.

ImageMeanImageMeanImageMeanImageMeanImageMeanimageMean (output_object) singlechannelimage(-array) → object (byte / int2 / uint2 / int4 / real)

Result of averaging.

Example (C)

compose3(Channel1,Channel2,Channel3,&MultiChannel);
mean_n(MultiChannel,&Mean);
