Sentence examples for adjustable sequence from inspiring English sources

When a sufficient number of test subjects have performed the test, the average quality of the sequences chosen by the subjects is supposed to describe the quality level of the adjustable sequence that is perceptually equivalent to the quality level of the fixed sequence.

In the second study, reported first in [8], the roles of the fixed and adjustable sequences were swapped: the level of channel distortion was adjusted instead of source distortion.

The 16 different adjustable sequences contained different levels of source distortions (i.e., each one encoded with different QP).

In total, there were 12 fixed sequences (4 contents × 3 fixed QP levels) and 132 adjustable sequences (4 contents × 3 fixed QP levels × 11 BER levels).

This resulted in 40 fixed sequences (10 contents × 4 fixed QP levels) and 160 adjustable sequences (10 contents × 16 fixed QP levels).

Sample frames of these contents are shown in Figure 3. Six different combinations of QPs were used for the fixed and adjustable sequences (see Table 2).

These quality metrics were performed either between the distorted sequences (fixed or adjustable sequences) and the original, undistorted sequences (for PSNR, VQM, MOVIE, and SSIM), or on the distorted sequences alone (for NRIQM), in order to objectively evaluate the quality of the fixed and adjustable sequences against the original versions.

In order to evaluate the overall performance of each metric, we have computed the root mean squared error (RMSE) between the normalized quality values of the fixed sequences and the normalized mean quality values of the adjustable sequences in each test case.

The main element of the user interface is a slider that is used to choose the video source file among n sequences with different quality level, together forming an adjustable video sequence.

In the DSAQFA method proposed in our earlier study [7], test subjects are instructed to select from a range of adjustable quality sequences the one that matches as closely as possible the subjective quality of a fixed reference sequence.

The cleanadaptors program scans the reads, identifying sections, which show 85% or higher matching with any of a series of adaptor sequences (the threshold is adjustable) in the sequenced reads and then the program removes the adaptor sequences from the sequenced reads.
