Abstract
In order to improve the real-time transmission ability of motion video data, it is necessary to compress video data. A real-time compression method for motion video data based on wavelet analysis and vector quantization is proposed. The two-dimensional wavelet transform is used to decompose the motion video and transform the time and frequency domain, and the quantization error is used to compensate for the video data. According to the method, the motion video data under the Internet of things are processed by LBG vector quantization, and the method of error compensation coding is used to smooth the noise of the motion video data under the Internet of things. The motion video of the N codebook is coded and combined with the multi-layer wavelet scale decomposition method, the real-time compression of the motion video data under the Internet of things is realized. Simulation results show that the proposed method can achieve better real-time compression and transmission of motion video data, and lower output error rate.
