  • avfilter/delogo : Set default band to 1

    avfilter/delogo : Set default band to 1

    The original interpolation algorithm behaved poorly on the borders and
    
did not even guarantee continuity at the borders. For this reason, a
    
second interpolation/blending pass was required on the borders to make
    
them seamless.
    

    However, since the interpolation algorithm was improved in June 2013,
    
the border issues no longer exist. The new algorithm does guarantee
    
continuity at the borders, making the second pass useless. A larger
    
band always increases the cumulated interpolation error. In most cases
    
it also increases the average interpolation error, even though the
    
samples in the band are only partially interpolated.
    

    For this reason I would like to get rid of the "band" parameter. As a
    
first step, let’s change its default value from 4 to 1 and document it
    
as deprecated.
    

    I have benchmarked this change on a combination of input sources and
    
realistic logo areas. Lowering the band value from 4 to 1 resulted in
    
8 to 39 % less interpolation error per frame (or 1 to 34 % less
    
interpolation error per luma sample.)

  • avfilter/delogo : Fix show option when band is small

    28 septembre 2015, par Jean Delvare
    avfilter/delogo : Fix show option when band is small

    The code assumed that the outermost interpolated pixels were always in
    
the fuzzy area defined by the band option. However if the band value
    
is small, there may be no fuzzy area on a given plane. In that case,
    
option show did not work, no rectangle was drawn (or only on the luma
    
plane, depending on the band value and chroma plane subsampling
    
factors.)
    

    Fix the problem by not making any assumption on where the outermost
    
interpolated pixels will be.
    

    The new code was verified to produce the same result as the original
    
code when the band value is not small.
