[x264-devel] variance-based adaptive quantization

[Khaled MAMOU]

Dear all,
First, congratulations for the great work!
I am interested in learning more about the "variance-based adaptive
quantization" algorithm
(http://git.videolan.org/?p=x264.git;a=commitdiff;h=dc4f40ce74c996a1e15021b82ab71ebcb8652d0b).
The idea seems to be simple and efficient. Please, is there any
theoretical foundations behind the formula used to adjust the QP based
on the variance of each MB?

Best regards,
