H.264帧内预测算法的优化及应用

Optimization and Application of H.264 Intra Prediction Algorithm

现存的视频压缩方法,大多为提高视频的压缩效果和减少压缩时间,而采用电路复杂并且造价高昂硬件电路.针对该情况,文章根据帧内预测算法的准确性与高效性,采用H.264帧内预测算法并对其进行优化,在此基础上设计硬件电路,后结合JPEG图像压缩算法对视频进一步压缩,从而达到简化硬件电路、缩短编码时间、提高数据的传输速率与可靠性的目的.测试表明,研究能够达到上述目的且具有相对成本低廉的市场优势,在无线视频监控领域上具有较好的发展前景.

Existing video compression methods, mostly in order to video compression and reduce the compression time, using the complexity and high cost of hardware circuit. According to the intra prediction algorithm for accuracy and efficiency, we used H.264 intra prediction algorithm and optimized design it, design the hardware circuit on this basis, after the combination of the JPEG image compression algorithm to compress the video further. The method to simplify the hardware circuit, reduce coding time, the purpose of data transmission rate and reliability. The tests show that in this study has achieve the above objectives and wish a relatively low-cost market advantage, and a good development prospects in the field of wireless video surveillance.
