Malcolm Bixby – Panoramic Mosaic Stitching

Obligatory Hub Lawn Tests with the terrible exposure patterns.

Mind that since Ms. Quinn deigned to use my artifact from the last project, I felt obligated to use one of hers J

Spot the professor:

Not terribly bad – roughly every odd photo is underexposed which plays terrible tricks on the Lucas-Kanade algorithm.

Using: 6 Levels & 9 Steps.

Tried 4L, 6S which fixed some of the vertical shifting (the images didn’t shift as much going from dark to light regions) but the horizontal

shift worsened.

Tried a mix of 6L, 9S except on images from dark to light, where I reduced the number of Levels & Steps hoping to maintain the smaller

vertical shift but minimize the excessive horizontal shifting…nope, didn’t work:

Mounted Camera Panorama: Denny Hall & Quad with obligatory Seattle Rain

using: 4 Levels & 6 Steps. Denny is a bit fuzzy due to the gentleman walking up the lane in both images.

Mounted Camera Panorama: UW Quad, again with obligatory Seattle Rain:

using: 4 Levels & 6 Steps, note the blurring of Smith Hall and of the tree in front of Savery Hall.

I suspect the blurring of the tree is due to the gentleman who happened by.

His image lies right on the edge of one of the pictures. I suspect the blurring in front of Smith is due to the triplet of

cap-guy walking through the Quad.

Mounted Camera Panorama: Same as above but jacking the number of steps up to 12, and using PhotoShop to remove

the errant gentleman:

This removed much of the blur, particularly around the tree. Smith Hall is still fuzzy, didn’t notice cap-guy until after I’d

processed the images.

Hand-Held Panorama: Egads! What a mess… Same location as above.

using: 4 Levels & 6 Steps.

Hand-Held Panorama: Attempt To Clean Up above. Using 6 Levels and (what the heck) 18 Steps.

Smith Hall is still a mess – but this did sharpen most of the other bits out. Savery & Raitt Hall look better than

the Mounted Panorama.
