Sentence examples for sum of distortion from inspiring English sources
We formulate the problem of video delivery as a constrained optimization problem of minimizing the sum of distortion of all video streams from all users, and map it to a restricted version of the Multiple Knapsack Problem (MKP) [8].
We obtained an improved correlation when comparing the sum of distortion energies and Δ EFMO with Eact (R= 0.82), implying that in a first approximation these two contributions can be considered additive and are both critically determining reactivitiy.
The objective of the GOP level CADF problem is to minimize the sum of distortions over a GOP for all the video streams, subject to the signal-to-interference-plus-noise ratio (SINR) and frame deadline constraints.
Although all proposed methods were implemented and tested with an additive approximation of UNIWARD, this distortion function is naturally defined in its non-additive version, meaning that changes made to neighboring pixels (DCT coefficients) interact in the sense that the total imposed distortion is not a sum of distortions of individual changes.
As shown in [55], if the error signal in a subband (i.e., the quantization noise) is white and uncorrelated to the other subband errors, the reconstruction distortion in the spatial domain is a weighted sum of the distortion in each wavelet subband.
They couldn't detect any apprecialby amount of distortion.
You are the sum of those distortions.
The end-to-end distortion (Dtotal), perceived by the end user, can generally be computed as the sum of the source distortion (Dsrc) and the channel distortion (Dchl).
We assume the total expected image distortion to be the sum of the expected distortion for each image substream [31].
where td = is the depth of the tree and is the sum of the accumulated distortions for all codewords in depth on the training sequence, defined as (10).
Essentially, the approach presented in[77] replaces the sum of various freeze distortions with an equivalent single freeze length for predicting the video quality.
