Table I. Error concealment for Intra coded videos: spatial error concealment with UPC for ROI.
in U.S.A.
Table II. Error concealment for Intercoded videos: hybrid temporal/spatial error concealment with U-Eigenflow for MVs/UPC for ROI.
in U.S.A.
Table 1. Error concealment performance of four models at INTRA and INTER coded scenarios
"... In PAGE 11: ... 13. Error concealment for the Inter coding scenario with: (a) motion compensation; (b) motion compensation and UMPC The PSNR performance of the decoded video frames is summarized in Table1 . In both the Intra and Inter scenarios, error concealment with UMPC performs the best.... ..."
Table 1: Mean Squared Error for different concealment approaches
"... In PAGE 5: ... We repeated the same procedure in constructing the tree without using the OMNIBIT. To obtain the results in Table1 , each MB in the test sequence is individually assumed to be lost, and the concealment MB for it is found using the concealment method named at the top of the column. The average Mean Squared Error is reported, averaged over the entire sequence in each case.... In PAGE 6: ... When OMNIBIT is not used, the concealment is fully standard compliant, and the results are nearly as good as when CART uses OMNIBIT. For comparison, we also simulated the multihypothesis EC algorithm proposed in [10] using optimal weight coefficients (which is shown in Table1 as the opt weights column). We found that, in our pulsed quality dual reference frame scenario, the algorithm did not give good results.... In PAGE 7: ... Table 3 shows the video quality results using this approach. The columns labeled ST Med and CART are the same as in Table1 . Under Customized CART tree , the column labeled MSE gives the MSE of the customized CART tree, and the column labeled % imprv.... ..."
Table 3. Comparison of different error concealment techniques with two motion estimation algorithms when the last frame is heavily damaged.
"... In PAGE 8: ... We should note that this idea is still at a preliminary stage since the assumption of piecewise linear motion over a larger time interval may not always be appropriate. The results are presented in Table3 . This table shows the comparison of results when the next frame is predicted from a damaged frame and when the next frame is predicted from the previous reference frame.... ..."
Table 1: Numerical results of error concealment upon the 1st 100 frames of the Bream and Akiyo sequences for various error rates.
"... In PAGE 4: ...01 5.26 225 11.75 227 11.84 Table1 summarises the corresponding numerical results produced by the different concealment techniques upon the first 100 frames of both the Bream and popular Akiyo test QCIF sequences for various different error rates. For the Bream sequence, the results conclusive show an improved performance with for instance at a 10% error rate; IDSSEC, Bezier [13] and Hermite [10] techniques respectively producing absolute errors of 15, 53 and 52 pels while the respective relative errors are 2.... ..."

Table 1. Comparison of different error concealment techniques with two motion estimation algorithms when a small portion of motion vectors and residue information are lost.
"... In PAGE 6: ... With these experiments, we can examine the impact of losing the motion vector and residue for different recovery techniques and different motion estimation algorithms. Table1 provides the numerical results of the simulations under these error conditions. It is evident from this table that the OBMC approach performs better than the median filter approach, and the median filter approach performs better than the repeat last approach.... ..."
Table 3. Comparison of di erent error concealment techniques with two motion estimation algorithms when the last frame is heavily damaged.
"... In PAGE 9: ... We should note that this idea is still at a preliminary stage since the assumption of piecewise linear motion over a larger time interval may not always be appropriate. The results are presented in Table3 . This table shows the comparison of results when the next frame is predicted from a damaged frame and when the next frame is predicted from the previous reference frame.... ..."
