中文拼音 [yīnxiànqūyù]
陰線區域
英文
crosshatched area-
The cathode rays are always beamed on a fresh area of the anode surface.
陰極射線總是射向陽極表面的新區域。Secondly, each region ’ s orientation line is calculated to prejudge the regions that contain the shadow regions, and the regions that contain shadow region are marked. thirdly, the marked region ’ s body color vector is calculated, and it is matched with that in the shadow database, after that, the shadow region can be obtained accurately
接著計算前景中每個區域的方向角分割線,預判斷每個區域中是否含有陰影區域,標記出含有陰影區域的區域,然後對有標記的區域計算其體色向量,和陰影數據庫中的體色向量進行匹配運算,精確定位出陰影區域。It produces a solid outline at points being shaded where the surface faces away from the camera ( typically around the outside edge of the surface being rendered ), and crosshatching on the & quot; interior & quot; portion of the surface
它在面對攝像機的遠處(典型地是被著色表面的外輪廓邊)被著色點上產生了一個單一的輪廓線,並在表面的內部區域產生一個交叉陰影。Umbra lets you emphasize the intensity of shadows in the area fully protected by the direct rays shot by the lighting source : the light transition between fully shadowed areas and fully lit areas change more quickly
日蝕允許你增強被光源發射直接光線包圍的區域中的陰影深度:在完全陰影區域和完全照亮區域之間,光線急劇轉換。Dealing with faces illumination variation based on dynamic directional gradient vector flow snake and gamma algorithm a new dynamic directional gradient vector flow snake ddgvf snake algorithm was presented which can detect the image shadow and highlight contours of the unknown face images. according to the given standard face database, the image gray median could be c.
使用一種動態方向梯度矢量流snake ddgvf snake演算法來檢測未知圖像的陰影和高光區域,根據已知的標準人臉圖像庫中圖像的灰度分佈,計算出灰度中值,然後採用加權非線性gamma灰度矯正演算法來歸一化待識別圖像的光照變化,使之與已知的標準庫中的圖像灰度一致。A statistical method is used to obtain the background model, which is updated real time in order to adapt to illumination changes and scene changes. after threshold operation, morphologic operation and connected region area measurement are introduced to solve background disturb problem. at last, shadows are detected using hsv color space information and gets exact moving regions
該方法首先利用統計的方法得到背景模型,並實時地對背景模型進行更新,以適應外界光線變化和場景本身的變化,閾值操作后,用形態學和連通域檢測的方法進行后處理,消除噪聲和背景擾動帶來的影響,最後,在hsv顏色空間下檢測出陰影,得到準確的運動對象區域。Inclusion of our special adaptive multiple ray sampler code to enhance rendering speed on scenes that use multiple “ blurry ” rendering effects like blurry tracing, area shadows or quasi monte carlo global illumination
整合了我們特殊的自適應多重光線采樣代碼,對于那些使用了多重模糊渲染效果* *的場景(比如模糊追蹤* * 、區域陰影、半蒙特卡洛全局光照等) ,可以提高渲染的速度。In cathode ray tubes, the small area on the screen surface which is bombarded by the electron beam
在陰極射線管中,屏幕表面上受到電子束轟擊的小區域。To sum up the use of these three buttons, let ' s say that if your computer has a low computing power and if you want to use area lamps and raytracing anyway, you could find useful to set a low samples value ( like 2. 00 ) and activate the buttons dither and / or noise in order to simulate slightly softer shadows
總結這三個按鈕的用法,我們可以得出結論:如果你的計算機主頻不高,但是你想使用區域照明和光線追蹤等特性,你最好設置一個較低的采樣值(例如2 . 00 ) ,並且激活抖動和/或噪聲,從而簡單地平滑一下陰影。It researches the background model based on gradient and chromaticity which can update background in real - time, which provide exact information of objects to next module. in tracking objects module, the thesis applies kalman filter to estimate and predict the objects ’ moving state. in association module, the mahalanobis distance is utilized to get the similarity among objects. “ matching matrix ” is presented to get the best matching object
研究了基於色度、梯度建立背景模型檢測目標的方法,能實時更新背景模型,基本避免場景中光線變化的影響,有效消除了目標陰影,能準確檢測目標,並得到目標輪廓及提取視頻目標,為下一階段針對目標區域的處理提供較完整的目標信息。You gain access to other parameters when you activate the ray shado button in the shadow and spot panel ( area light ' s shadow panel )
當你激活陰影和聚光燈面板(區域照明陰影面板)中的射線陰影按鈕時,就可以控制其它參數了。分享友人
