arithmetic coderの例文

• A bitwise arithmetic coder such as DMC has two components, a predictor and an arithmetic coder.
• A bitwise arithmetic coder such as DMC has two components, a predictor and an arithmetic coder.
• These estimates determine the two sub-ranges that the arithmetic coder uses to encode the bin.
• The bits selected by these coding passes then get encoded by a context-driven binary arithmetic coder, namely the binary MQ-coder.
• This is fed into an arithmetic coder, which adds only a small fraction of a bit to the output sequence if the more probable pixel is then encountered.
• The arithmetic coder in PAQ is implemented by maintaining for each prediction a lower and upper bound on " x ", initially [ 0, 1 ].
• In practice, though, so-called range " encoders " tend to be implemented pretty much as described in Martin's paper, while arithmetic coders more generally tend not to be called range encoders.
• The arithmetic coder makes an identical series of range splits, then selects the range containing " p " " x " and outputs the bit " x " " i " corresponding to that subrange.
• :: : : : : The compression ( 7z ) is so efficient because it's an intricate LZ code followed by entropy coding using ( I believe ) a dynamic Markov model driving a range coder ( similar to an arithmetic coder, I think ).
• In general, arithmetic coders can produce near-optimal output for any given set of symbols and probabilities ( the optimal value is & minus; log " 2 P " bits for each symbol of probability " P ", see source coding theorem ).
• The arithmetic coder maintains two high precision binary numbers, " p " low and " p " high, representing the possible range for the total probability that the model would assign to all strings lexicographically less than " x ", given the bits of " x " seen so far.
