The improved SI technique is also applied to a new hybrid spatial and temporal error concealment scheme to conceal errors in WZ frames.
Therefore, the error concealment schemes proposed for traditional video coding schemes cannot be directly applied to conceal errors in WZ frames.
They sometimes conceal errors in an effort to avoid a legal ordeal.
It is not unethical to err, but it is unethical to deliberately persist in error or to conceal errors that harm others.
Robert Khuzami, the S.E.C.'s director of enforcement, said that while quantitative managers often keep their models secret even from their own compliance and risk managers to protect trade secrets, that secretive structure "cannot be used to conceal errors and betray investors".
The spatial EC defined in H.264/AVC JM 11.0 is used to conceal errors in key frames.
Image inpainting is an important research field in image restoration that can be used to retouch damaged images and videos, remove text, and conceal errors in videos.
Although the error concealment methods tested in the previous section (KMMSE, WTM, VC, and XFSE) perform well for images, they are not designed to conceal errors in compressed videos.
They are designed to conceal errors only within homogeneous spatial regions and, therefore, cannot recover lost packets because these packets may contain information from several frame blocks distributed along several frames.
Such fallacies are quite puzzling to the tyro, who, unless he is aware of the principle involved, may well overlook the subtly concealed error.
