论文摘要
Fisheye摄像机获得的广角视频序列表现出可能不太符合标准图像和视频处理技术，例如错误隐藏。本文引入了一种时间错误隐藏技术，旨在通过在透视域中进行部分错误隐藏后，通过将重新注射应用于Equisolid域，旨在通过将重新注射应用于Equisolid域，旨在通过将重新注射应用于Equisolid域。与所使用的测试序列的纯解码器运动矢量估计相比，将此技术与常规解码器运动矢量估计相比，平均增长率为0.71 dB。对于选定的帧，最大收益高达2.04 dB。
Wide-angle video sequences obtained by fisheye cameras exhibit characteristics that may not very well comply with standard image and video processing techniques such as error concealment. This paper introduces a temporal error concealment technique designed for the inherent characteristics of equisolid fisheye video sequences by applying a re-projection into the equisolid domain after conducting part of the error concealment in the perspective domain. Combining this technique with conventional decoder motion vector estimation achieves average gains of 0.71 dB compared against pure decoder motion vector estimation for the test sequences used. Maximum gains amount to up to 2.04 dB for selected frames.
