此外,匹配的特徵相似性度量結合了非均勻有理b樣條的畸變估計和局部的圖形窗口交叉相關性,從而融合了幾何結構和圖像灰度的相似性。Relative to uniform inlet pressure, the distorted or actual profiles may have a rather profound effect on engine performance.
與均勻的壓力分佈比較起來,畸變的或真實的壓力場對發動性能具有相當大的影響。And the correction of a step wavefront produced by a step phase plate is accomplished successfully. 6. according to the phase modulation characteristic of an lcslm, arbitrary complicated wavefronts were modeled. the result shows that lcslm can be use to test the wavefront sensors and controller if lcslm has wider dynamic range and perfect optical quality
六、通過利用液晶空間光調制器的位相調制特性,成功地模擬產生了任意畸變波前,指出若該器件有更大的位相調制動態范圍和均勻性,將有可能成為校驗波前傳感設備和波前畸變控制系統性能的有力工具。Abstract : the crystal structures obtained by static solidification and vibration solidification were compared. it was showed that, in the case of vibration solidification, the orientation growth of the columnar crystal was not obvious, the equiaxial crystal appeared more early. the grains of both types of crystals were quite fine, hardness in the full section was relatively high, and the hardness distribution was uniform. in the former case, the solute segregation in dendritical austenite more severe, and there were lumps of distortion inclusion
文摘:對球鐵金屬型靜凝固與振動凝固的結晶組織對比表明:後者柱狀晶方向性生長較弱,等軸晶出現較早,且兩者的晶粒均較細,全斷面硬度較高且分佈均勻;前者枝晶奧氏體內溶質偏析大,有畸變夾雜團塊。Asymmetric lens distortion
透鏡不均勻畸變差The design results and the performance evaluation of f - theta200 and f - theta500 are given in detail. the designed lenses are simple and compact and their cost are low. the focusing performances are within diffraction limit, the relative illuminations quite uniform and the distortion relative to the f - theta linear relation small
詳細給出了f - theta200和f - theta500的像質評價和研製結果,所研製的f - theta鏡頭具有工作面積大、結構簡單緊湊、加工成本較低、聚焦性能達到衍射極限、工作面上相對照度分佈均勻、能量集中度高和畸變小等優點。Tpih ( tube - bending process using local induction heating ), used as a new process method to prevent the producing of unequal distribution of the wall and ovality in the tube, has been widely applied in fields of petroleum chemical industry, light industry, pipe engineering, aeronautics and astronauts industries, etc.
加熱彎管是防止管材彎曲截面形狀畸變與壁厚不均勻的一種新的工藝方法,廣泛的應用於石油化工、輕工、管道工程、航空航天等工業部門。14 rattarangsi a, chin r t. scale - based detection of corners of planar curves
第二,使用耦合的非均勻有理b樣條表示任意圖形畸變。Image and vision computing, 1999, 17 : 489 - 499. 4 gottschalk p g, turney j l, mudge t n. efficient recognition of partially visible objects using a logarithmic complexity matching technique. the international journal of robotics research, 1999, 8 : 110 - 131
它從以下幾方面解決以上問題:第一,高尺度的分析突出了圖像的高頻部分,因此能夠更準確地匹配圖像特徵第二,利用非均勻有理b樣條表示圖像畸變,這對大多數現實的圖像幾何畸變都適用。The results indicate : under different condition, the uniform twisted state and the disturbed state, the disturbed state and the saturation state and the saturation state and the uniform twisted state can form bistable state
計算結果說明均勻扭曲解和畸變解,畸變解和飽和解,飽和解和均勻扭曲解在不同條件下,均可構成雙穩態。They have three solutions : the uniform twisted solution, the saturation solution and the disturbed solution
它們有三種解:均勻扭曲解,飽和解和畸變解。分享友人
