Displaying 3d matrix as image

[Arun Mallya]

Hi,

I have a 3d matrix (the output texture) which I want to interpret as RGB channels and display it as an image.

imshow(image) displays a white image

imagesc() gives out of range error

imshow(mat2gray()) gives the proper image but with colors distorted as compared to original sample texture image.

I checked the values in the output texture image and they correspond to those in the input texture image. Still, it cannot be displayed.

What do I do !?

try abs(cat(3, im(:,:,1), im(:,:,2), im(:,:,3)));
then, use imshow again?
Not sure, you can have a try

Nope, I found the reason.

You have to typecast the matrix to uint8, uint16, or the like.

out = uint8(out);

Ut now works.
