Sentence examples for slice losses from inspiring English sources

On the other hand, quality impairments in the key-frames, due to slice losses, lead to worse side information, so that more parity bits are necessary for the correction.

The idea is to consider the motion activity in the block as initial guess of the distortion caused by the initial packet loss; Bitstream-based video quality metric: in these systems, several bitstream parameters, such as motion vector length or number of slice losses, are used for predicting the impairments visibility in MPEG-2, SVC [42], or H.264 [44] 44] and HD H.264 [45] videos.

Therefore, the video slice loss rate (VSLR) of slices in priority i is VSLR i =PER i.

Note that computation of slice CMSE requires decoding of the entire GOP for every slice loss, which introduces computational overhead.

Let the original uncompressed video frame at time t be f(t), the decoded frame without the slice loss be f ̂ ( t ), and the decoded frame with the slice loss be f ~ ( t ).

During the transmission of the first one (corresponding to frame n.23 in the plots of Figures 5 and 6) a slice loss has occurred, leading to a very significant quality impairment.

In this paper, the total distortion of a slice loss is computed using the cumulative mean square error (CMSE), which takes into consideration the error propagation within the entire GOP [9, 34].

Therefore, we define a function 'normalized F,' denoted by F ¯, which represents the weighted distortion contributed by the slice loss rates and their corresponding normalized CMSE values, as F ¯ = ∑ i = 1 r CMSE ¯ i α VSLR i. (5).

And even banks eager to securitise their loans sometimes retain the "residual"—the most risky slice where losses hit first.

By working with UPS and restructuring its own ground-delivery network, the German-owned firm plans to slice its losses in America from a forecast $1.3 billion this year to $300m by 2011.

Multi-slice signal losses in out-of-slice locations were simulated for IVI methods, and then measured experimentally across a range of slice numbers.
