该方法能够保持传统小波变换的优势,高效的去除时域冗余信息,同时通过提升小波的整型变换能够快速实现的特点,降低了计算复杂度,减小了内存需求,提高了小波视频编码器的性能。 - Decades of years , the tool of wavelet analysis does well in the research area of digital image process , but the performance of wavelet - based video coders is inferior to that of dct - based video coders . this thesis studies the video coder based on wavelet and is absorbed in the motion estimation in the wavelet domain
近二十几年来发展起来的小波技术在图像编码方面取得了瞩目的成果,但在视频编码方面还处于研究阶段,目前基于小波的视频编码器性能比不上基于dct的视频编码器性能。 - At the same time , this paper does some improvement on the prototype so as to make it be used in the remote video surveillance more properly . the improvement method which can achieve higher encoding efficiency is to add the pretreatment of motion detection before the encoding of the video pictures
同时，为了将视频编码器和解码器原型更好的用于远程视频监控系统，本文提出了对原型进一步改进的方法，即在对视频图像压缩编码之前加入运动检测的预处理过程，从而进一步提高编码效率。
