Hi, My name is Ravi and I am PhD student. I am using hugin to stitch multiple pictures as part of my project. I work with 32 bit float images. I was able to load the images into hugin and stitch them. I also got similar problem where the panorama is either completely black or completely white. I am sure the procedure as described by Tom in the previous message will work fine, because I have been following similar procedure for a different application. But, I am having with the output. I am saving the images as tiff images but I am can not view the images. I tried to open the image using ImageJ, Matlab and Gimp. I can not access the images. The error in ImageJ says, 'unsupported interleaved sampleperpixel 2' and similarly in matlab, I see each pixel has two channels. I am assuming the extra channel in the monochrome image is alpha channel.
I appreciate if there is any way to create the panorama such that the 32bit data is preserved and accessible. I am a Biomedical Engineering student with average knowledge of image processing. Thank You, Ravi.
