基于场景差异与小波分解的视频图像压缩传输方法研究

Research on Video Image Compression Transmission Method Based on Scene Difference and Wavelet Decomposition

本文提出图片动态差异提取法,采用小波变换对差异图片进行分解,传输时根据动态差异的大小,选择发送小波变换的细节部分,或者近似细节部分。接收端根据图像动态差异,选择合适的近似部分,与细节部分重新构成新的图片。实验表明,与传统图像传输的方法相比,本方案可以有效提高传输的效率,降低系统传输的成本。

This paper proposes a dynamic difference extraction method for pictures. The wavelet transform is used to decompose the difference pictures. When transmitting, the details of the wavelet transform are selected or approximated according to the size of the dynamic difference. The receiving end selects an appropriate approximation part according to the dynamic difference of the image, and reconstructs a new picture with the detail part. Experiments show that compared with the traditional image transmission method, this scheme can effectively improve the transmission efficiency and reduce the cost of system transmission.
