How to visualise Hyperspectral Image in colour?

5 views (last 30 days)
I am using hyperspectral datasets from this website: http://www.spectir.com/free-data-samples/. I can visualise a picture in gray but not in colour. How can I convert the gray image to an RGB colour image?
Thanks in advance

Put each spectral channel into one of the color channels:
rgbImage = cat(3, spectralChannel1, , spectralChannel3, , spectralChannel8);
imshow(rgbImage);
or whatever channels you want to use.

i think this may be helpful for you load('ref_crown3bb_reg1.mat') x=reflectances(:,:,17); figure; imagesc(x); colormap('gray');brighten(0.5); y = reflectances(:,:,25); figure; imagesc(y); colormap('gray');brighten(0.5); z=reflectances(:,:,33); figure; imagesc(z); colormap('gray');brighten(0.5); all=cat(3,x,y,z); figure; imshow(all)

See this paper that describes a variety of ways to convert spectral bands to RGB: http://my.ece.msstate.edu/faculty/du/JSTARS-VIS.pdf
