quantization level 解釋
量化電平
  • quantization : 分層量子化把連續量轉換為數字
  • level : n 1 水平儀，水準儀；水準測量。2 水平線，水平面；水平狀態；平面，平地。3 水平，水準；水位；標準；...
  1. Usually, we consider a sampling technique in which each sample is obtained by averaging a diamond portion of the picture, as we know, a large amount of information of a image in nature mainly gathered the small area, at the same time <, . but to finger print gray image, a fine degree of quantization is particularly important for samples taken in regions of a picture across which the gray level changes slowly

    目前國內外圖像濾波常用的方法有線性濾波和非線性濾波。線性濾波有完善的理論基礎，數學處理也簡單，易於fft實現，在濾波技術中佔有及其重要的地位，但對于像素受污染的指紋圖像而言由於脈沖噪聲的重脫尾，處理效果並不太理想。
  2. This algorithm adopts peak error or maximum amplitude error criterion to control the level of distortion in pipeline leak signals, and doesn ’ t change the subsequent location error of adaptive time - delay estimation in the case of a small quantization error, so as to implement the near - lossless compression of pipeline leak signals

    該近無損壓縮演算法設計了基於峰值誤差準則的量化方案對管道泄漏信號的失真度進行控制，在量化誤差較小時並不影響后續自適應時延估計的定位誤差，從而實現對管道泄漏信號的近似無損壓縮。
  3. We also use matlab to simulink effects on which some compression parameters such as vbs and quantization level have

    在此基礎上，用matlab模擬jpeg的壓縮參數，具體分析了如何通過改變jpeg壓縮參數來改善傳輸速率。
  4. （ b, sensitive and accurate : subhealthy district position quantization measures the rate of accuracy and more than 90. 6 %, even if there are three, five cells of the pathological change, can measure out immediately too, this is a traditional detecting instrument far not achievable level

    靈敏準確：亞健康區部位量化檢測準確率達90 . 6 %以上，即使病變的細胞只有三、五個，也可即時檢測出來，這是傳統檢測儀器遠遠不能達到的水平。
  5. This paper first research on main technologies used by avs standard, which include prediction, transform, quantization, in - loop filter, and entropy encoding, and then focus on the 2d - vlc entropy coder of avs, which is context - based adaptive coder. this encoder operates on run - level pair, and it uses the type of current block and value of current coefficients to switch vlc code - table. these tables are designed according to the distribution of transformed coefficients, and this way is much better than using only one table to code all residual coefficients in one 8x8 block

    本文首先詳細研究了avs標準的核心技術，包括預測編碼、變換量化、環路濾波器以及掃描和熵編碼等，之後重點研究了avs標準中使用的基於上下文的2d - vlc變長編碼方法，這種方法編碼的是（ run ， level ）數對，同時根據當前編碼塊的類型和殘差系數這兩種上下文信息來切換碼表，這些碼表是預先根據變換系數在不同位置的分佈信息設計好的，這樣要比只使用一個變長碼表來編碼塊內所有位置上的殘差系數的壓縮效果要好得多。
  6. This paper studies the portal sites of administrative county, and investigates the status about portal sites in more than 2, 000 counties of 30 provinces and autonomous regions ( except for hongkong, macao, and taiwan ) by measuring in quantization, through constructing the multi - level index systems to measure samples, proposes several ideas that could develop the county agriculture website

    本文對我國行政縣（縣級市）門戶網站進行統計研究，從量化的角度對我國大陸30個省市自治區（不包括港、澳、臺地區） 2000多個縣市的門戶網站的現狀進行調查，通過建構多層次的指標體系對樣本進行測量，提出了幾點有利於縣域農業網站發展的建議。
  7. Quantization analysis to the entrance achievement was made in september, 2001. the experimental classes and the contrast classes were chosen among four classes of almost the same level in two different schools

    對2001年9月入學成績進行量化分析，分別從兩類不同學校中各選出四個水平基本一致的班級確定為實驗班和對比班。
