  20          old one still supported)
  21         BUGFIX for zero-transforms
  22
  23 0.93
  24         single pass version filter_deshake
  25         made stabilize part print the transforms to the file right away
  26
  27 0.92
  28         boxblur added and unsharp filter removed for motiondetection
  29
  30 0.91
  31         spiral search for matches in compareSubImg
  32
  33 0.90
  34         complete restructuring into own library
  35         Fixed point arithmetic used for transform code
  36         motiondetection optimized with ORC: speedup by factor 4
  37         ORC 0.4.14 is now required
  38         added tests for speed and functional tests
  39         removed biquadratic interpolation routine
  40
  41 0.80
  42         keep borders with stabilized last frame (as it should be).
  43         Pointed out by Guido Torelli.
  44
  45 0.79
  46         speed optimizations using SSE by Alexey Osipov
  47         search tree cut, spiral search and sse:
  48          together speedup factor ~8 of stabilize run
  49         stepsize is increased stepwise
  50         keep border at transform plugin improved
  51
  52
  53 0.77
  54         interpolation routines improved a lot, thanks to hints on ffmpeg list
  55         added bicubic interpolation that uses 4x4 pixel (useful for large zoom values)
  56         bilinear interpolation is now the default
  57         transform plugin uses last transform for the remaining frames
  58          -> this enables to use the transform plugin for constant transformations
  59
  60 0.76
  61         BUGFIX in calcFieldTransYUV caused SEGFAULT
  62
  63 0.75
  64         two meta parameter introduces: shakiness and accuracy and
  65         removal of fieldnum, fielsize, maxshift, maxfieldnum
  66         field placement changed: Now they fill the frame perfectly
  67         added bluring such that stepsize can be much larger: much faster now!
  68         linear interpolation is now the default
  69         uncertain angles are set to 0 (more robustness)
  70
  71 0.70    selects a maximal number of fields according to their contrast
  72         nicely distributed over the frame
  73         Todo: remove fieldnum, allowmax (now false), and compressed parameter
  74         Todo: add accuracy parameter instead of maxfields
  75         Bugfix of contrast routine (error in the calculation of maxi)
  76
  77 0.62
  78         different interpolation functions. No interpolation is default and
  79          seems fine in most applications.
  80         field placement changed. Now they fill the frame better.
  81         "compress" option moves them more to the center (vertically)
  82         fields and their areas and transforms can be drawn on the frame.
  83
  84 0.6
  85         new field placement allows for any number of fields
  86          and respects aspect ratio
  87         fields with low contrast are ignored
  88         non-symmetric field setups are possible
  89
  90 0.5
  91         global and per-frame zooming supported
  92         optimal zoom value is calculated to avoid moving border effect
  93         add filter unsharp to sharpen the frames
  94         write parameters to transforms file
  95
  96 0.44
  97         bugfixing
  98         finished RGB #support
  99         transforms file format supports comments
 100
 101 0.42
 102         input filename and tc_list stuff used
 103 0.41
 104         code style from transcode used
 105 0.4
 106         moved to CVS version we use a cleaned median to select the right
 107         transform from the fields
 108 0.3
 109         Support RGB (untestet)
 110         maxshift default 50
 111         allowmax added
 112         scan only every second shift and then make a second small
 113           scan around the best match
 114         removed black rectangle around transformed frame
