I have some data measured with a coarsely-quantized clock. Let's say the real data are q<- sort(rexp(100,.5)) The quantized form is floor(q), so a simple quantile plot of one against the other can be calculated using: plot(q,type="l"); points(floor(q),col="red") which of course shows the characteristic stair-step. I would like to smooth the quantized

...DCT ... (like above) \ -> -> sum impulse factors -> iDWT -> LPC -> LSP -> quant i.e. use a wavelet transform to seperate out impulsey signals and compress them in the time domain. The decoder complexity really isn't increased much (just one more dequant/LPC and a sum). I think there are optimized versions of the haar DWT that go really fast too.. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/

Hi all, Just a stupid question The IDctSlow function on file idct.c has this line : ip[0] = (ogg_int16_t)((_Gd + _Cd ) >> 0); The ip[0] , _Gd and _Cd are of type ogg_int32_t My question is: The result of (_Gd + _Cd) can be a number with more than 16 bits ? (yes, it can be because they are int32, but the algorithm could guarantee something about that... I dont know...) If

Hello, I have improved a little the NHW codec.I have improved the dequantization in the wavelet HH band, and little improved the -l2 (and lower) quality setting.I have also added a -l3 lower quality setting (-15Ko, exp), I have increased the quantization for this other setting, and I start to remove higher wavelet coefficients, but this is not optimal... The artifacts st...

Hi all, Does Theora Community have an interest in a multi-thread decoder implementation? I'm starting to work with multi-thread and I thought that Theora Decoder is a good choice for me, because I had been working with it in a FPGA implementation and I have experience with the library. I'm thinking in working with LoopFilter at first. Do you think I could start with it or there is a
