一种时空采样矩阵的确定方法

A method to determine space-time sampling matrix

在分析数字视频系统时空采样矩阵基本特性的基础上,依据时空采样矩阵的定义,结合实际视频系统扫描和采样结构,采用多点标定,得到了一种确立数字视频流时空采样矩阵的方法.并通过一个应用实例,在时频域上给出了完整的数字视频流结构分布和相应参数,以及两种视频流之间转换的方法,证明了多点标定方法的实用性和有效性.

After analyzing the basic characteristic of space - time sampling matrix in digital video, the paper presents an effective method of establishing digital video stream, which combines the practical image system scanning and sampling structures and explores multi - calibration. As an example of applications, we give an integrated structure distribution and corresponding parameters of digital video stream and propose a transferring method for two digital video streams, which proves the practicability and validity of the method of multi - calibration.
