1.1 use openMP to do parallel execution
1.0 = 0.98 (just because of API changes the version number was bumped
0.98...
small measurement fields added that only scan around mean
diagnostics in show=1 and show=2 use lines now.
fix zoom detection/treatment
zoomspeed param for optzoom
gaussian filter for cam path optimization
0.97
optzoom = 2: adaptive zooming added
border bluring for interpolation>=bilinear
spurious black pixels bug fixed
0.96
libavfilter plugins work
flexible support of pixel formats, ala ffmpeg
0.95
virtual tripod mode
0.94
local motions are now stored in the file (file format changed,
old one still supported)
BUGFIX for zero-transforms
0.93
single pass version filter_deshake
made stabilize part print the transforms to the file right away
0.92
boxblur added and unsharp filter removed for motiondetection
0.91
spiral search for matches in compareSubImg
0.90
complete restructuring into own library
Fixed point arithmetic used for transform code
motiondetection optimized with ORC: speedup by factor 4
ORC 0.4.14 is now required
added tests for speed and functional tests
removed biquadratic interpolation routine
0.80
keep borders with stabilized last frame (as it should be).
Pointed out by Guido Torelli.
0.79
speed optimizations using SSE by Alexey Osipov
search tree cut, spiral search and sse:
together speedup factor ~8 of stabilize run
stepsize is increased stepwise
keep border at transform plugin improved
0.77
interpolation routines improved a lot, thanks to hints on ffmpeg list
added bicubic interpolation that uses 4x4 pixel (useful for large zoom values)
bilinear interpolation is now the default
transform plugin uses last transform for the remaining frames
-> this enables to use the transform plugin for constant transformations
0.76
BUGFIX in calcFieldTransYUV caused SEGFAULT
0.75
two meta parameter introduces: shakiness and accuracy and
removal of fieldnum, fielsize, maxshift, maxfieldnum
field placement changed: Now they fill the frame perfectly
added bluring such that stepsize can be much larger: much faster now!
linear interpolation is now the default
uncertain angles are set to 0 (more robustness)
0.70 selects a maximal number of fields according to their contrast
nicely distributed over the frame
Todo: remove fieldnum, allowmax (now false), and compressed parameter
Todo: add accuracy parameter instead of maxfields
Bugfix of contrast routine (error in the calculation of maxi)
0.62
different interpolation functions. No interpolation is default and
seems fine in most applications.
field placement changed. Now they fill the frame better.
"compress" option moves them more to the center (vertically)
fields and their areas and transforms can be drawn on the frame.
0.6
new field placement allows for any number of fields
and respects aspect ratio
fields with low contrast are ignored
non-symmetric field setups are possible
0.5
global and per-frame zooming supported
optimal zoom value is calculated to avoid moving border effect
add filter unsharp to sharpen the frames
write parameters to transforms file
0.44
bugfixing
finished RGB #support
transforms file format supports comments
0.42
input filename and tc_list stuff used
0.41
code style from transcode used
0.4
moved to CVS version we use a cleaned median to select the right
transform from the fields
0.3
Support RGB (untestet)
maxshift default 50
allowmax added
scan only every second shift and then make a second small
scan around the best match
removed black rectangle around transformed frame
