FAQ Auto-Alignment

 

Questions and answers to the 3D-Easy - 1-Click-Auto-Alignment.

What is the aim of the function "3D-Easy - 1-Click-Auto-Alignment"?
The aim is the complete and full automatic correction (shift, rotation, scalation) of 3D source images in order to reduce vertical deviations in the middle of the images which have to be aligned. Furthermore, there is also a reduction of the horizontal deviation.
The 3D-Easy - 1-Click-Auto-Alignment aligns source images with high accuracy, without any further manual user settings. A manual alignment of the source images, which is demanding in time and requires a certain expertise, is no longer necessary with 3D-Easy - 1-Click-Auto-Alignment. The results of the
3D-Easy - 1-Click-Auto-Alignment are usually much better than those which were aligned manually.
Due to the reduction of the horizontal deviation, the position of the 3D window is located in the middle of the depicted scene. The position of the 3D window can simply adjusted any needs with the possibilities of the manual alignment in 3D -Easy SPACE (here horizontal shift by 3D- serial shift or with reference points and operated option „only horizontal shift“).

What are the special features of the new function "3D-Easy - 1-Click-Auto-Alignment"?
The 3D-Easy - 1-Click-Auto-Alignment is a very powerful function to auto align 3D lenticular source images (normally at least 4). 3D-Easy SPACE is the first and only lenticular software worldwide with such an auto alignment. The 3D-Easy - 1-Click-Auto-Alignment can also be used for the perfect auto alignment of 3D stereo images pairs.
Further special features:

  • no use /installation of additional software, driver, plug ins etc. are necessary
  • all functions are contained in the program 3D-Easy SPACE (Standard or Professional)
  • if desired, there is a pixel detailed pre -and post alignment possible under the graphic surface of the program
  • the results obtained just after the automatic correction can be estimated very well by the animated preview
  • the processing of very large images is supported (e.g. larger than 10.000 x 10.000 pixel per image)

During the shift, there are „non-integer pixel values“ after having used
"3D-Easy - 1-Click-Auto-Alignment". Do „non-integer“ pixel shifts make any sense, e.g. 3, 4 pixel to the left?
Pixels are the smallest picture elements and cannot be split up any further. „Non-integer“ pixel shifts are useful in following situations:

  • with shifts only (without rotation and scalation), „non-integer“ pixel shifts are applied with bicubic interpolations because the „neighboring“ pixels are considered in the calculation
  • „non-integer“ pixel shifts are applied in combination with rotation and / or scalation with the method „next neighbor“ as well as with „bicubic interpolation“.

There are „non-integer“ pixel shifts or sub-pixels in version 5 of the software 3D-Easy SPACE with the introduction of the function 3D-Easy - 1-Click-Auto-Alignment and "bicubic interpolation". The values for „non-integer“ shifts are saved in the 3DE-project file.

What kind of images are not suitable for "3D-Easy - 1-Click-Auto-Alignment"?
Animations or flip images are not suitable for 3D-Easy - 1-Click-Auto-Alignment because differences in images in vertical direction are wanted (e.g. rising blossom). This is the reason why images should not be aligned with 3D-Easy - 1-Click-Auto-Alignment.
If the 3D-Easy - 1-Click-Auto-Alignment cannot find an optimum, it will be shown with a "-" in the file list. Such cases occur if the image contents are not suitable for an automatic alignment (e.g. none or only a few striking points or if the image contents differ too much from each other).
