Experimental results indicate that comparing to exhaustive search, the proposed method improves the coding speed and compression ratio greatly with slight quality degradation of decoded image.
实验结果表明,相对于全局搜索,所提方法大幅地提高了编码速度和压缩比,而解码质量只略有下降。
Experimental results show that the coding speed is much enhanced while high compression ratio and well-reconstructed image can be obtained.
实验结果表明,该方法大大提高了编码速度,而且能获得高压缩比和满意的恢复图象质量。
In this paper, motion estimation technology, as one of the significant issues to video compression encoding, is studied to increase coding speed.
本文针对影响视频压缩效率和速度瓶颈之一的“运动估计技术”展开研究。
Fractal Image-compressed is carried out after DWT or DCT to improve coding speed and get higher CR and PSNR, but quality of reconstructed-Image is not satisfactory.
运用小波域及DCT域下的分形压缩图像方法,提高了编码速度,得到较高的压缩比和信噪比,但重构图像质量还存在块状效应。
The human visual weighting factor change the order of coding rather than the value of coding. The algorithm has much faster coding speed and better compression effect.
基于人眼视觉特性的加权因子改变编码位序而不是编码值,该算法有更快的编码速度以及较好的压缩效果。
Since ISZW used successive integer squares as quantization thresholds, it shortened the distance between two consecutive thresholds, but increased coding times, thus reduced coding speed.
但是,由于ISZW使用连续的整数平方作为量化阈值,缩短了相邻阈值间的距离,却增加了编码的次数,降低了编码速度。
