相移失真
英文
phase shift distortion-
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。Compared with traditional cluster, the cooperative - type - cluster has carried the sync net packets from all real server ’ s network cards to director and set up a priority queue of sync net packets for dmcs, then it has transmitted them through the cooperation of nodal servers and directoer, it has made that the nodeal server lost efficiency suddenly or automatically joined or broke away from the cluster not influence the whole system ’ s normal running again ; meanwhile, it can avoid reducing handling capacity even appearing phenomenon of “ living locking ” in high load
與傳統集群相比，合作式集群從各真實服務器端網卡報文隊列中分離出請求報文移至負載均衡器端，建立針對分散式測控系統的請求任務報文優先權排隊隊列，通過節點服務器與負載均衡器合作進行報文轉發，使得節點服務器突然失效或自動加入脫離集群不再影響整個系統的正常運行;同時，也能避免在高負載下處理能力降低甚至出現「活鎖」的現象。Before more advanced lithography tool is produced, in order to use current tools to manufacture vdsm ic, reticle correction methods such as perturbing the shape ( via optical proximity correction ( opc ) ) or the phase ( via phase - shifting masks ( psm ) ) of transmitting aperture in the reticle are proposed by the industry
在波長更小的光刻系統出現前，為了能利用現有設備解決集成電路的可製造性問題，工業界提出了對掩模作預失真（光學鄰近校正）和在掩模上加相位轉移模（移相掩模）等的掩模校正方法。On the following, on the basis of formulas given above, three kinds of effects due to ionosphere are presented : image shift due to group delay which was caused by the difference between the group velocity and the velocity of light in the ionosphere ; image distortion due to ionospheric dispersion which can create second phase error of lfm signals ; the last, the phase perturbation caused by the irregularities of the ionosphere can reduce the coherent length and affect azimuthal resolution
文中主要研究了電離層的三種影響：信號經過電離層傳播的群延遲引起的成像偏移；電離層的色散效應給線性調頻信號帶來二次相位誤差，導致圖像退化、失真；以及電離層的閃爍、湍流等不規則性引起的信號相位起伏。在此基礎上，比較分析了不同波段、帶寬條件下電離層的影響。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。9 malvar h s. low - complexity length - 4 transform and quantization with 16 - bit arithmetic. ftp : ftp. imtc - files. org jvt - experts 0109 san vceg - n44. doc. 10 gordon s, marpe d, wiegand t. simplified use of 8 8 transforms - proposal
從與dct失真的角度分析該44變換與h . 264 mpeg - 4 avc中的44變換具有相同的失真度，並且也可以通過加法和移位實現整個變換過程，並且所有運算都能在16位精度內完成。Love comes to those who still hope even though they ' ve been disappointed, to those who still believe, even thought they ' ve been betrayed, need though they ' ve been hurt before
愛選擇那些曾經失望過但仍滿懷希望；曾經被背叛仍堅信不移；曾經被傷害仍相信真愛的人。分享友人
