Sentence examples for between the key frames from inspiring English sources

The GOP size (N G) refers to the number of WZ frames in between the key frames plus one.

This is done by computing the average luma variation per pixel between the key frames at the decoder, which is compared to a threshold.

The weight values (w i, w j ) are determined by distance ratio between the key frames to the target frame with the condition, w i + w j = 0.

Thus, the motion between one key frame and the current WZ frame, with a GOP size of 2, will be half of the motion between the key frames.

In this process, the allocation of bits between the key frames and the WZ frames plays a central role in the final RD performance.

For IMSI, Figure 23 shows the luma pixel variation between the key frames for the three video sequences at the highest RD point.

The SI frame at t + S/2 that is located at the interposition between two key frames is generated with the key frames, and then MVs are estimated from the SI frame at t + S/2 to the key frames, and the compressed MVs in a lossless mode are sent to the encoder side.

The spatio-temporal correlations between the partially error-concealed frames and the key frames are then exploited to refine and smooth the estimated motion vectors using the technique presented in Section 3.3.

(ii) Then, the key frames are filtered with a low-pass filter and the high frequency content is obtained as a difference between the original key frames and their filtered version.

Notice that distributing the same total bitrate in a different way between WZ and key frames may even lead to better RD performance, for example, by investing more bits in the key frames at the cost of a less stable video quality, but the resulting strong quality variations along time are highly undesirable.

First the key frames are mean filtered.
