Providers can ensure video quality by applying algorithmic compression techniques such as chroma subsampling , which uses color variation undetectable to the human eye 供應(yīng)商通過應(yīng)用諸如色彩子取樣等算法壓縮技術(shù)確保視頻的質(zhì)量,所謂的色彩子取樣使用了人眼觀察不到的顏色變化。
Due to the fact that the properties of infrared detector array ca n ' t be satisfied to produce a image with high resolution because of the level of manufacture , the phenomenon of subsampling and serious aliasing emerges . in order to reduce these phenomenon and improve the image resolution the technique of microscanning is introduced 紅外探測器陣列由于受到工藝水平的限制,不能制成用于產(chǎn)生高分辨率紅外圖像所要求的密度,一般會產(chǎn)生空間欠抽樣圖像,圖像中有嚴重的混淆現(xiàn)象,為了減小這種混淆、提高分辨率,引入微掃描技術(shù)。
This paper proposes a multiple description mesh - based motion coding method , which generates two descriptionsfor mesh - based motion by subsampling the nodes of a right - angledtriangular mesh and dividing them into two groups . motion vectorsassociated with the mesh nodes in each group are transmitted overdistinct channels 丟包由于網(wǎng)絡(luò)阻塞路由延遲以及從高容量網(wǎng)絡(luò)向低容量網(wǎng)絡(luò)交換等和信道失效由于衰落效應(yīng)和突發(fā)錯誤等使得在internet和無線信道上壓縮視頻數(shù)據(jù)的可靠傳輸成為新的研究課題。
