专利名称Patent Title
一种交互式多视点视频编码方法
Interactive multi-view point video encoding method
点评:一种交互式多视点视频编码方法,通过在编码过程中抛弃所有P帧的色度分量,提高多视点视频的编码压缩效率和编码速度,降低服务端向用户端传输编码码流的传输量;利用相邻帧的运动矢量信息对所有P帧进行颜色化操作,较为精确地重构出P帧的色度分量信息;在用户端利用视差矢量信息来计算乘性误差和加性误差,从而利用乘性误差和加性误差实现对解码并重构后得到的图像进行颜色校正,既保证了视点间的颜色一致性,又实现了交互式多视点视频应用。

Comment: The invention discloses an interactive multi-view video encoding method. By discarding the chromaticity component of all P frames in the encoding process, the encoding compression efficiency and the encoding speed of the multi-view video are increased, and the transmission amount of the encoding stream which is transmitted by a server to a client end is reduced; colorization operation is carried out on all the P frames by using motion vector information of adjacent frames, thus reconstructing the chromaticity component information of the P frames accurately; at the client end, multiplicative error and additive error are calculated by using parallax vector information, thus realizing that the color of the image after decoding and reconstructing is corrected by using the multiplicative error and the additive error, ensuring color consistency among the view points and realizing the application of the interactive multi-view video.
