qcif 中文意思是什麼

qcif 解釋
幀速率
  1. Quarter common intermediate format qcif

    四分之一通用中間格式
  2. Qcif quarter common intermediate format

    四分之一通用中間格式
  3. Its sampling rate can reach up to 30 frames per second when using qcif format, while 15 frames per second can be obtained for cif format

    當採用cif格式採集時，幀率為15幀秒，採用qcif格式採集時，幀率可達到30幀秒。
  4. Based on the configuration features of tms320c6416, the encoder of h. 264 is implemented by using assembly language. the h. 264 encoder that we have implemented on tms320c6416 has a high processing speed. it can comprocess 27. 5 frames of qcif video images per second in real - time when the cpu frequency of tms320c6416 is 720mhz

    本文實現的h . 264編碼器性能為:在主頻為720mhz的tms320c6416晶元上對2路qcif格式的視頻圖像進行處理，在一定的保真度條件下，編碼速度達到了27 . 5幀/秒。
  5. This method is especially suitable for small mobile devices such as handheld pcs, palm - size pcs and mobile phones that possess small display screens and light computational power, and work in low bandwidth wireless networks. the system rtbvideo based on the technique mentioned above typically provides qcif - size video with a frame rate of 5 - 15 fps for a 9. 6 kbps bandwidth in the internet

    在上述技術的基礎上開發的基於internet網際網路的實時視頻傳輸系統rtbvideo ，能夠提供格式為qcif （ 176 144 ）的視頻，人體輪廓清晰，畫面穩定流暢，且在9 . 6kbps帶寬下能達到每秒5 - 15幀。
  6. Using the above algorithms, h. 263 baseline video - encoder implementation can encode more than 40fps in qcif resolution on a pentium mmx 500 - mhz computer. almost ali of the low bit - rate video compression techniques degrade quality. to combine the video quality evaluation with hvs, the relationship betvveen the motion activity and perceptual video quality are studied, and a video quality evaluation method based on motion activity is proposed, in which video defmition and smoothness are defined

    本文提出一種基於運動特徵的視頻質量評價方法，考慮了人眼對視頻信號感受質量與畫面運動劇烈程度之間的關系，分別討論了反映視頻質量的視頻清晰度和流暢度，評價結果更符合人眼視覺特性，並且這種評價對編碼具有一定的指導作用。
