What NumberOfSamples and SamplesPerPixel mean?

The “infonfo” command shows the characteristics of an image. I don’t understand two of them. They are:

1. NumberOfSamples

2. SamplesPerPixel

Can anyone please help me?

Is this a built-in command? I can't seem to find the documentation on it. If it's a third-party plugin, can you provide a link to the site?

Do you mean imfinfo()?

Anyway, the first one sounds like maybe the number of color channels???? And the second one is either the number of color channels or the number of bits per pixel. Where did you find this information?

Yes, I mean it. I mean imfinfo('image.jpg').

Hello everyone. do you guys know if is possible to change (3 samples per pixel) to (1 samples per pixel)? I am trying to upload some images to a software. It seems that is the main issue. Is possible to change the atributes with mathlab?
