==Resynthesis==
First attempts recombining warped, centered images.
*Results below sum 1 row of 24 images, from initial set of 432 images (24 x 18) with 1.0 offset in each direction.
*Camera locations specified in inches (offset from keyframe, negative or positive)
*Different "focal planes" correspond to different offset scalar value, from 0.0 to 10.0, as indicated in upper left of image.
*<code>python alignImagesRansac.py images/3images/ images/3images/test0002.png results/3images</code>

==openFrameworks / openCV weighted sum for resynthesis==
requires full set of aligned images and a txt file detailing camera positions

==openFrameworks app for GLSL Resynthesis==
Recombination using GLSL shader. Images are montaged into one large texture.
 
openFrameworks application (xCode, oF v0.8):

==Plenoptic Home==
576 co-registered images, acquired with the photo gantry.
 
you can see that the images are slightly out of order/acquired at the wrong time. this is a problem with the acquisition script.
