  • A novel macro - block layer rate control algorithm in low bit - rate
    一种低码率下的新型宏块级码率控制算法
  • With a view to dct that costs the longer computing time , fast dct is proposed , and the method of prejudgment of an macro - block of all zero coefficient of dct is adopted in this paper , which makes about 40 percent dct computation reduced , consequently , the encoding speed of h . 263 encoder can be further increased
    263编码器的编码速率;对运算量较大的dct给出了快速算法,并对全零dct系数块采用提前判断的方法,从而省去了约40的dct运算,进一步提高了h 263编码器的编码速率。
  • Firstly , we directly use the motion vectors of macro - blocks defined in mpeg - i / ii compressing standards and filter the immobile macro - blocks . then , we build a skin color model in ycbcr color space using the convergent property of skin color , and we present the gaussian model skin recognition method and positive - negative look - up table method in details . and we analyze the texture of skin after wavelet transform and present a bayesian method based texture recognition method and a high texture filtering method
    根据皮肤的运动性,首先直接利用mpeg -中的压缩标准中有关宏块运动预测的方法,提取宏块的运动矢量,将没有运动的宏块过滤掉;然后,利用皮肤颜色的聚合性,在ycbcr颜色空间建立了皮肤的颜色模型,并分别阐述了基于高斯分布模型的皮肤检测法和正反概率表方法;最后,通过对皮肤进行小波变换后的纹理进行统计后,发现有效的利用皮肤纹理特征,可以比较有效的过滤掉那些具有类似于皮肤颜色的背景,分别阐述了基于贝叶斯方法的纹理检测方法和高纹理过滤法。
  • For video codec , after analyzing and researching the newest standard h . 264 , an efficiency algorithm was proposed in this paper using self - feature , spatial correlation and temporal correlation to judge the encoding mode of one macro - block . through this method , the best prediction mode can be obtain before encoding , then , the coding time can be reduced dramatically with a little expense of bit - rate . for video transmission , in this paper , a transmit method was proposed using tcp / ip protocol under the environment of local networks
    首先,在分析及研究最新的视频编码标准h . 264的基础上,利用宏块自身的特点和其时间、空间的相关性来判断宏块应该采用的编码模式,从而提前得到该宏块的最佳编码模式,新方法有效地克服了原标准算法中穷举式的复杂算法,在压缩码流只有少许增加的情况下,大幅度地提高了帧内及帧间编码的速度。
