Added some utility function in matlab/lib
old function update
added some new methods for new approach
minor improvement/update on find_surface_boundary & boundary_visual_test
mri_tank progression notes
fixed an error on dicom 3D coordinate calculation
visual_test now uses both coronal and sagittal sets
changed locate_surfaces to deal with average of 3 images, instead of sum of 3
rough edge out, able to remove broken sections, and able to detect gap/discontinuity
removed short edge, remove peaks, remove small bumps, smoothed edge
surface edge algorithm improvements. tested several slices, include slices at both end, and some where in the middle, all worked pretty well.
add a plotting function in surface_edge and cleaned up some plotting related code.
able extract S4 using S2 boundaries, but the coordinate is off. need to check conversion.
added get_mri_tank_surfaces. Currently collects S4 using left and right boundaries of S2 without issue.
mr_tubes writing wrap up. Still need to add pics
'mr_tubes' update
add dropbox changes
correction parameter estimation roughly done.
added a brief conclusion
added abastract
