Is it possibile combine an RGB image and an IR image in a FOUR-BAND tiff image?

Hi all,

I'm looking for a function to build a four-band image. I have an RGB image and the corrispective IR image (in greyscale), and I need to merge them in a 4-band image.

I tried 'imfuse' but the result is just a 3-band (RGB) image a bit darker.

Any suggestion?

Thanks a lot

Tiff class can be used. The IR can be placed into Extra Samples. I seem to recall that you can also directly write an array with 4 panes in Tiff class as long as you give the right bit depth information.

I also encountered a hint that you can imwrite an array with 4 panes to tiff file and that it will write as-if it were rgba

Tiff class works. Thanks!
