|In this section I will go through the process of stitching
a spherical panorama from the scanned images through to the final
colour/contrast corrected image. Each stage will include a little more
complexity to the previous until the final panorama is completed.
This demonstration will assume that the lens parameters (v,a,b,c) have
been previously calibrated, providing a good starting point. The accuracy of
seams will be displayed by creating multi-layered PSD images without masks
and setting the blending mode of the upper two layers to Difference.
This will map the entire source images and display the overlapping
regions as black IF they are perfectly aligned. The closer the match
between images, the blacker the overlapping regions will appear.
Let's start by having a close look at the source
images and the circumstances under which they were acquired.
