Why bit plane 8 of my image is almost black?

I am trying to reconstruct an image by combining bit plane 8 and bit plane 7 of my original gray image. However I get an almost black picture which I think it shouldn't be like that. When I display image in matlab without any process on it, it is different from the original image. What should I do?

Check the class of the image......and change it accordingly.

Hi

It seems, the image which you are displaying might be in double or single format. Convert it to uint8 format using uint8 command. Also, make sure the range of image pixels value to be lies between 0 and 255.

If it won't work, then can you share a samle image? It will be more helpful.
