MJPEG Tools Svn

Why set "mpeg = 2" twice :)

Updated to reflect the new code & the new meaning for command-line
parameters.
More hints on proper usage.

The BUGS section used to say there was a need for a dynamic noise
reduction tool. We now have 2.

Changed reference to "yuvdenoise -I" to "yuvdeinterlace".

Rewrote the top-level denoising. The search-border is no longer used.
For every pixel-group, the denoiser now keeps the match-count-throttle
matches with the lowest SAD, and flood-fills each until the resulting
region is at least match-size-throttle pixel-groups big, then applies
that region right then and there. This new algorithm is a lot simpler
than the previous one, but seems to work a lot better.

Also, a nasty bug was fixed in the way the extent of applied regions
are removed from the search-window cells. VERY nasty bug. It
technically produced broken data.

Image quality has improved DRAMATICALLY. Performance has increased from
anywhere between 20% (for normal video) to 35% (for pathological video).

Purge() now takes an x/y offset, to allow moved regions to be processed
correctly.

Now purges the pixel-sorter tree every 10 frames, instead of every 100
frames. Changing algorithms require changing fudge factors...

Changed the default match-size throttle (since it means something
different now).

partly implemented general-sampling-theorem interpolation.
The image-quality now is far far better. memory handly is
a remaining problem, as some functions need to overshoot for
reasons of speed...
So it may not work on MACs/PPC... :((
