This composite image of a set of perspective drawings of St Louis by Camille Dry in the mid 1870’s was stitched together using PTGui as an exercise to see if image stitching methods could produce a well aligned composite image.
I haven’t attempted to do any colour enhancement or matching between images. Whether or not the customised alignment of images produces any significant improvement I will leave up to you to decide. After looking at the extra plates in the book I noticed that the plate of the bridge spanning the river looked very similar to the image in the composite, and as it turns out it fits almost perfectly even though it is drawn at a different angle. Even the traffic at the top end of the bridge and the 2 boats below the first span are almost identical.
The viewer displaying the composite above is Zoomify’s full screen viewer. The icon at the right end of the toolbar should display the viewer in full screen… and yes I am aware of issues with some installations of Firefox and Safari. I’m currently investigating other display options using the same image set and have a trial viewer using Open Layers.
