  • distortion : n. 1. 歪扭，扭曲。2. 【電學】（信號、波形等的）失真；【物理學】（透鏡成像產生的）畸變；【醫學】扭轉，變形。3. 竄改，歪曲，曲解。adj. -al
  1. Because of the aberration of fish eye lens resulting from fabrication procedure, there exists serious geometrical distortion, which arises the problem of correcting the fish eye image

    由於魚眼鏡頭製造過程中產生的誤差等原因，所拍攝的圖像幾何畸變還是比較嚴重的，這就產生了對魚眼圖像進行幾何校正的問題。
  2. First, resistance to geometrical distortion was obtained by using moment normalization ; second, we focus on the phase of fourier - mellin transform. before detecting watermark, synchronization could be retrieved by using the phase information. to eliminate the influence of pixel value distortion generated during print / scan process, a dft - based robust watermark algorithm was designed, which could successfully detect watermark from a severe distorted image

    另一種思路是根據圖像經過旋轉、縮放、平移后，其傅立葉?梅林變換域只有相位受到影響的特點，從其相位中提取幾何失真信息，然後再進行相應的失真補償，從而消除幾何失真的影響；對于列印掃描過程產生的像素值失真，本文也提出了一種基於dft的魯棒性演算法，能在較嚴重的圖像失真情況下，成功檢測水印。
  3. ( 4 ) the algorithm for correcting the geometrical distortion of fish eye image

    （ 4 ）魚眼圖像的幾何畸變校正。
  4. On the basis of analyzing roundly origins of rs image geometrical distortion and existing methods of geometrical correction, the route of geometrical correction for the images from the miniature uav rs system was brought forward

    通過全面分析遙感影像幾何變形的來源和現有幾何糾正方法，提出了一條基於ccd相機誤差綜合標定和與正射影像配準的幾何糾正技術路線。
  5. Experiment results show that this algorithm can restore distortion caused by global and local or no - linear geometrical attack, and it is practical and effective

    實驗結果表明，該演算法可以從全局和局部或非線性幾何攻擊中恢復失真，是實用和有效的。
  6. It is clearly that only two geometrical parameters i. e. maximal misalignment angle ( ) and distortion width ( s ) need to be determined experimentally

    纖維彎曲模型（ fdm ）只有兩個幾何參數（最大纖維偏轉角和變形區寬度）需要由實驗確定。
  7. A synchronization template is used to combat geometrical distortion such as cropping, scaling, and rotation

    使用同步模板以抵抗剪切、尺度變化和旋轉等操作帶來的幾何失真。
  8. Which is simple with high efficiency, and has the ability of anti - geometrical distortion while robust to some image processing such as filtering and smoothing, etc. to some extent

    其特點是計算簡單，精確度高，具有抗幾何畸變性，對濾波、平滑、壓縮等圖像操作有一定的魯棒性。
  9. In the design of watermark encoder, through the combination of side information and watermark, our system also obtained the robustness against copy attack. ( 3 ) effort on obtaining the resistance to print / scan are made. to solve the geometrical distortion problem appeared during the process of print / scan, two schemes were proposed

    （ 3 ）對抗列印掃描的水印演算法做了一些研究和實驗，對于列印掃描過程中出現的幾何失真，本文提出了兩種解決方案，一種是利用矩函數提取圖像的特徵信息，並將圖像變換到規范化的空間，在此空間進行水印的嵌入和檢測工作，從而避免了幾何失真的影響。
