== Structure From Motion (SfM) Demo ==

'''General tips:'''
* JPEG is less reliable
* Color palate manipulation in smartphone photos can present issues
* Lossless formats preferable
**.TIFF 
**.RAW

'''Steps:'''
* Open Agisoft PhotoScan
** In Workspace, "Enable Chunks"
** Add two chunks
*** Time_0
*** Time_1
** Add photos
** Estimate image quality
*** Filters out photos with motion blur, etc.
*** Quality ranges from 0-1
*** Poor quality photos (perhaps <0.7) can be eliminated
*** Glossy and reflective surfaces are difficult to resolve
** Workflow --> Align Photos
** Sparse point cloud
*** The number pad is helpful for orientation in the 3D workspace
** Dense point cloud
** Create Mesh
** Batch Process
*** Useful for the "Save Project After Each Step" feature
*** Not useful for traversing through all of the processing steps
