A special case of multiple frame prediction is the dual frame buffer, where an encoder uses both an immediate past frame and a long term past frame for motion compensation. Using a dual frame buffer together with intra/inter mode switching improves the compression performance of the coder. In this work, we investigate the effect of feedback in making better mode-switching decisions in the conte...

Survey statisticians make use of the available auxiliary information to improve estimates. One important example is given by calibration estimation, that seeks for new weights that are close (in some sense) to the basic design weights and that, at the same time, match benchmark constraints on available auxiliary information. Recently, multiple frame surveys have gained much attention and became...

We have built the research model of dual resonant frame parameter generator based on actual circuit diagram implemented in laboratory to evaluate mechanism frame, two-frequency generator. The oscillator produces desired frequency w2 which depends pump and w1. On basis model, we successfully tested dual-frequency transmitter, makes it possible manufacture RF oscillators with low phase noise, the...

For any fixed fusion frame, its optimal dual fusion frames for reconstruction is studied in case of erasures of subspaces. It is considered that a probability distribution of erasure of subspaces is given and that a blind reconstruction procedure is used, where the erased data are set to zero. It is proved that there are always optimal duals. Sufficient conditions for the canonical dual fusion ...

Numerous human genes display dual coding within alternatively spliced regions, which give rise to distinct protein products that include segments translated in more than one reading frame. To resolve the ensuing protein structural puzzle, we identified 67 human genes with alternative splice variants comprising a dual-coding region at least 75 nucleotides in length and analyzed the structural st...

In this paper, the tangent, binormal, normal and unit Darboux vectors of the dual curve on the one–parameter dual spherical motion are obtained with respect to a unit dual orthogonal frame for dual 3–space D.

Based on analyzing the related technologies of the original video retrieval, we proposed an algorithm of adaptive dual-threshold shot boundary detection for the game video of TV. At the beginning, we convert each frame to the HSV space, set high and low ratio of threshold according to the frame difference. Then, the average value of frame difference in the sliding window is calculated to receiv...
