Motion picture's compress code and decompress decode in real time is the key part of highspeed wireless video transmission system 運動圖像實時壓縮編碼和解壓縮解碼是高速無線視頻傳輸系統(tǒng)的核心部分。
In order to obtain satisfying vision and transmission effect, effective image data compress coding, is the key technology to solve 為了達到令人滿意的視覺和傳輸效果,對圖像數(shù)據(jù)進行有效的壓縮編碼,是需要解決的關鍵技術之一。
The purpose of digital image compress coding is to token the image within the limit of bit, and to maintain the quality of renew image 數(shù)字圖像壓縮編碼的目的就是要以盡可能少的比特數(shù)來表征圖像,同時又必須保持恢復圖像的質量。
Secondly, because wavelet transform can realize time-frequency localization and multi-resolution, it has been the main aspect of current image compress coding research 其次,圖像經(jīng)小波變換后,對小波系數(shù)的壓縮是小波變換編碼的關鍵步驟。
This requires the image-compression technology to be not only more efficient in compressing images, but also to be more flexible in dealing with compress coding ratio 這就要求圖像壓縮技術不僅有良好的壓縮效率,而且還要能靈活地處理壓縮碼率。
The analoge voice from the trunking system was pcm coded, compressed coded, packtized and then transmitted to the server by udp / ip link in the voice gateway 語音網(wǎng)關把來自集群系統(tǒng)的模擬語音,經(jīng)過pcm編碼,語音壓縮編碼,分組,rtp包封裝,經(jīng)udp/ip鏈路傳輸?shù)郊合到y(tǒng)服務器。
Human face detecting technique has gained extensive application in many fields such as human face identification, crowd control, intelligent user interface, content based image search, image compress coding and so on 該技術在人臉識別、人群監(jiān)控、智能人機交互接口、基于內(nèi)容檢索和圖像壓縮編碼等領域得到了廣泛的應用。
The g729a, a new issued speech compressed coding standard at 8kbit / s, is one of the optional coding standards of h . 323, which is multimedia meeting system standard based on ip network 729a是國際電信聯(lián)盟新頒布的編碼速率為8kbs的低速率語音壓縮編碼標準,它是基于ip網(wǎng)絡的多媒體會議系統(tǒng)標準h323可選的語音壓縮編碼標準之一。
As the development of video compress coding, flow media technology and network communication technology, digital video collecting system exhibits strong vitality . it replaces the analog collecting system generally 近年來,隨著流媒體技術、視頻壓縮編碼技術、網(wǎng)絡通訊技術的發(fā)展,數(shù)字視頻采集系統(tǒng)迅速崛起,逐步地替代現(xiàn)有的模擬采集系統(tǒng)。
