- A novel macro - block layer rate control algorithm in low bit - rate
一種低碼率下的新型宏塊級(jí)碼率控制算法 - 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編碼器的編碼速率；對(duì)運(yùn)算量較大的dct給出了快速算法，并對(duì)全零dct系數(shù)塊采用提前判斷的方法，從而省去了約40的dct運(yùn)算，進(jìn)一步提高了h 263編碼器的編碼速率。 - 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
根據(jù)皮膚的運(yùn)動(dòng)性，首先直接利用mpeg -中的壓縮標(biāo)準(zhǔn)中有關(guān)宏塊運(yùn)動(dòng)預(yù)測(cè)的方法，提取宏塊的運(yùn)動(dòng)矢量，將沒(méi)有運(yùn)動(dòng)的宏塊過(guò)濾掉；然后，利用皮膚顏色的聚合性，在ycbcr顏色空間建立了皮膚的顏色模型，并分別闡述了基于高斯分布模型的皮膚檢測(cè)法和正反概率表方法；最后，通過(guò)對(duì)皮膚進(jìn)行小波變換后的紋理進(jìn)行統(tǒng)計(jì)后，發(fā)現(xiàn)有效的利用皮膚紋理特征，可以比較有效的過(guò)濾掉那些具有類(lèi)似于皮膚顏色的背景，分別闡述了基于貝葉斯方法的紋理檢測(cè)方法和高紋理過(guò)濾法。 - 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視頻編碼標(biāo)準(zhǔn)h . 264的基礎(chǔ)上,利用宏塊自身的特點(diǎn)和其時(shí)間、空間的相關(guān)性來(lái)判斷宏塊應(yīng)該采用的編碼模式,從而提前得到該宏塊的最佳編碼模式,新方法有效地克服了原標(biāo)準(zhǔn)算法中窮舉式的復(fù)雜算法,在壓縮碼流只有少許增加的情況下,大幅度地提高了幀內(nèi)及幀間編碼的速度。 - It's difficult to find macro-blocks in a sentence. 用macro-blocks造句挺難的
