UW Panorama

Provided images were rotated and scaled down to 480x640. All matching was done with the same initial alignment of (250, 0). Some bluring was still noticable in a couple overlaps. Perhaps a slighty off matching. The whole image also seems offset veritcally.

Park Panorama With Handheld

Images were processed in gimp (Layer:Colors:Curves) to try and tone down the overexposure. Alot of handholding was necessary in the alignment phase. i.e. rather than a single alignment starting point for each, the starting points were modified so that it synced to the correct position. Part of this is because the rotation and vertical level were not nearly as consistent as the Kaiden head. Perfect matching is probably impossible as the camera parameters for warping where guesstimated through minimal trial and error.

One interesting side effect was my lack of enough overlap in some pictures (actually had to source an earlier test image as the start/finish image didn't overlap to the right at all). To match these with Lucas Kanade required a starting position that had very little overlap, however, this required that you reduce the number of levels of LK or else LK fell off the edge and without any overlap, the rest of the levels and iterations were lost. The lack of overlap also created large regions of 'blackspace' at the top and bottom where none of the warped pictures could provide data.

Park Panorama With Kaiden

Images were processed in gimp (Layer:Colors:Curves) to brighten some dark exposures facing away from sun. No handholding was necessary in this one, all images were aligned with an initial position of (250,0). Used a blend width of 80.

Park Panorama With Kaiden And Dog

The parameters for this mosaic were pretty much the same as above but it appears that the tripod moved between the time that the originals were taken and the additonals with the dog were taken. Some of the inital positions were modified as with the handheld to provide proper matching. Of course as these additional photos were taken later, their neighbor frames were lacking the dog so we get the ghosted version. Blend width was set to 80 as above.

Park Panorama With Kaiden, Dog and Almost Completed Laplacian Blending

This mosaic was created wih the same images as above but I was working on the laplacian pyramid blending. However, in dealing with the wierd crashes in Convolve and the FloatPyramids, I ran out of time. The is no real calculation of image mid points, only a few pyramid layers, and integer calculations (this probably killed it). You'll notice that the dog isn't ghosted anymore, probably mainly a result of not 'overlaping' images and alpha blending rather than the pyramid blending being any better. The blending, however smooth when completed would also still show weird effects in things like the lake where some images have light waves and the others don't have any, not to mention strange cloud formations. The problems in the image appear to be overflow related, when adding another layer, the image becomes a bit more psychedelic.
