Nesta carta, propomos uma técnica de ocultação de erros baseada em objeto de dois estágios para vídeo MPEG-2 transmitido em um ambiente de perda de pacotes em rajada. Uma perda intermitente de pacotes normalmente destrói uma grande área de vídeo codificado em MPEG-2. Na primeira fase, a área faltante é estimada intraimagem e ocultada em termos de uma abordagem baseada na região. Na segunda etapa, os objetos em movimento irregular em relação ao fundo são identificados e compensados a partir da imagem preditiva. Em comparação com abordagens convencionais de ocultação, o método proposto atinge melhor desempenho de PSNR e reduz os artefatos visuais.

Abstract: In this letter, we propose a two-stage object-based error-concealment technique for MPEG-2 video transmitted in a burst-packet-loss environment. A burst packet loss typically destroys a large area of MPEG-2 coded video. In the first stage, the missing area is intra-picture estimated and concealed in terms of a region-based approach. In the second stage, irregular-moving objects with respect to the background are identified and compensated from the predictive picture. As compared with conventional concealment approaches, the proposed method achieves better PSNR performance and reduces the visual artifacts.
