The study based on four-dimensional matrix DCT distance education video compression technology

Author(s): Ping Li

In the gorgeous era, the role of video in the human life growing. However, the highdefinition picture quality caused the difficulty in storage. In order to save more resources and maintain the quality of image, this article found out the method to solve the problem of remote compression through combining the four-dimensional matrix discrete cosine transform with statistical quantification firstly, then validated its effect in practical application according to the specific examples. The results shows that the compression through combining the integer transform with quantization achieved the desired effect.
