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。The image probably occurs color distortion that is influenced by optical equipment. in this paper, the hvs color invariance characters is construed, an complexion rectify algorithm based that is proposed, which can automatically adjust and compensate the image quality according to the external environment influence
攝像頭受外界光學環境的影響,採集的人像經常有顏色失真現象,本文通過對hvs的顏色恆常性特徵的分析,提出了基於hvs顏色恆常性的膚色校正演算法,可以自動校正和補償因外界影響而發生變化的人像膚色。The time base drift deduced by the change of temperature is discussed particularly and the compensation method of it is analyzed. finally, we also studied frequency band extension under time base distortion condition by simulation. the results show that the compensation of time base distortion can reduce the error of signal and then increase the accuracy of frequency band extension
首先,介紹時基失真的相關概念及其對測量信號的影響;其次,對時基失真特性測量的不同方法進行了理論分析和比較,並對分析信號法進行了模擬研究;再次,對時基失真的補償方法進行分析和模擬研究;並專門對溫度變化引起的時基漂移及其補償方法進行了簡要分析;最後,對時基失真條件下的頻帶展寬技術的模擬表明時基失真的補償可以減小信號的誤差,因而提高頻帶展寬的精度。It can be concluded after analysis that the speech distortion and the residual noise can be approximately regarded as multiplicative noise and additive noise, respectively. thus, we use a parallel model combination ( pmc ) algorithm, which is deployed in model space, to adapt the parameters of speech models to compensate the residual noise, or we use a cepstral mean normalization ( cmn ) algorithm in feature space to compensate both the speech distortion and the residual noise
分析表明,語音失真和剩餘噪聲可近似看作乘性噪聲和加性噪聲,因此可在模型空間利用并行模型合併( pmc )演算法通過調整模型參數對剩餘噪聲進行補償,或者在特徵空間利用倒譜均值歸一化( cmn )演算法對語音失真和剩餘噪聲同時進行補償。The adaptive predistorter given can achieve the predistortion compensation based on piecewise estimating hpa nonlinear characteristic curve and training hpa estimator nonlinear parameters via performing inverse transform with curve fitting section by section
