Study the bending laminar material. Tetrapak provided two sets of laminar material CD and MD and 3DImaging center scanned the material in 4 different angles, 0, 45, 90 and 180 when bent inward (in_in_) or outward (out_out_).
The goal was to investigate the properites of laminar mateiral while bending. First we segmneted the inner and outer layer of each samplein different angles, thereafter we measured the Euclidean distance between inner and outer layer as a measured property.
Then we registered the samples from 0, 45 and 90 degree to 180 degree and align the segmented meshes to point of concavity of 180 degree sample.

* [Abstarct to Northern Lights on Food](https://indico.linxs.lu.se/event/159/)
* Technical Report soon ...
Main code is Demo.m which goes through
1. PointSelection: annotate points close to the desired layers
2. LayerDetection: segment the inner and outer layers
3. PrepMeasure: prepare the segmeted layers to compute the measure
4. PrepRegistration: prepare the segemented layers for registration
5. Measure: compute the Euclidean distance in different units
6. Registration: register the 0, 45, and 90 degree samples to 180 degree
7. Transformation: transform and align the meshes
8. Export2inp: convert the mesh points to .inp files
