    注意：在圖像上方，已經被忽略的黑色輪廓線和真正的交叉陰影著色，在透視攝像機里明顯地表明格子紋理已經投射在表面上。
  2. First the sketch / datum plane is fitted by least - square distance, then the extruded direction or axis with the flank points of the cloud is extracted in quadratic paogramming arithmetic, and certain points projected to gain 2d sketched datas. feature points are defined to segment the sketch datas, and the sketch profile is generated by fitting separately the line and circle segment

    使用最小二乘方法擬合草圖基準平面，採用二次規劃方法提取拉伸方向和旋轉軸線，然後將數據點投影以獲取草圖數據，通過柵格劃分提取草圖邊界輪廓數據，再對這些邊界數據進行基於特徵點的分割，以直線和圓弧段擬合出草圖輪廓。
  3. In this paper, i will present some algorithms of polyhedral visual hull reconstruction : ( 1 ) polyhedral v isual h ull generation a igorithm b ased one dge - pool - searching, which constrains the 3 - d intersections into the 2 - d planes intersection via the epipolar theory to reduce the complexity a nd c an r educe t he t imes f or c ones t o b e p rejected o nto t he i mage p lanes, i n which we induced the index list to every points on the surface of object, and connected the related points to get sub polygons on surface and in turn get the mesh model, we replace triangulation process of disordered points cloud by edge - pool searching. ; ( 2 ) reconstruction based on degenerated - polygon - intersection, which have the following improvements on traditional bull intersection : using degenerated polygon to orga nize intersected area on cone face, which may be discontinuous ; a fast intersection algorithm of polygons on the cone face based on degenerated polygons, which is consistent between the continuous polygons and the discontinuous ones. the intersection of degenerated polygons is similar to the convergence of two ordered lists, which is comparably simple to the bull operation ; ( 3 ) reconstruction algorithm based on ray - tracing, in which all the rays that run through the vertex on silhouette of object will intersect with all the cones correspondent to other silhouette, and we have to calculate the intersection of all such line segments, the endpoints of which are considered to lie on the surface of object and we will get the point cloud on the surface of object

    同時利用共極線原理把三維計算投影到二維平面以降低求交計算的復雜度，該演算法可以減少光錐向圖像平面投影計算的次數，以邊池搜索取代散亂點集上進行的三角剖分； （ 2 ）基於退化多邊形求交的多面體可見殼模型重構，系統引入退化多邊形的概念，把錐體平面的交集中不連通的部分用一個退化多邊形來表示，並引入了新的基於退化多邊形的求交演算法，與傳統多面體可見殼重構相比，該演算法有以下幾點創新：在圖像平面以退化多邊形組織投影錐體和物體輪廓的交集，把任意錐面與物體輪廓的交集歸一到一個退化多邊形；基於退化多邊形的二維平面上多邊形快速相交演算法，該演算法在一定程度上就是兩個有序鏈表的合併，大大簡化了先前的布爾求交計算； （ 3 ）基於光線跟蹤的演算法，該演算法中所有通過輪廓頂點的光線和對應其它圖像輪廓的光錐進行求交計算，最後得到每次求交計算得到線段的交集，該線段的頂點就認為是物體表面點，從而得到物體表面的點雲。
  4. The heart of this algorithm is to track at least four fiducial points from frame to frame that construct the affine frame, and thus the occlusion contours between virtual and real objects can be reconstructed and reprojected

    演算法的核心是在每一幀圖像中追蹤至少四個基準點，構成仿射基，進而對虛擬物體與真實物體之間的遮擋輪廓進行重建和重投影。
  5. As to feature extraction, it can be divided into two parts because face features can be divided into geometrical features and algebraic features. while extracting geometrical features, the features of eyes, nose, mouth, eyebrows can be gained by some image processes : binary, sharpen, smooth, projection, calculating gradient and so on. in order to extract algebraic features, we can do some mathematical transformation for the digital images such as singular value decomposition, k - l transformation

    首先根據人臉圖像二值化圖中頭發塊的輪廓，確定出人臉的一次輪廓；然後在人臉的一次輪廓中以黑塊分析與投影分析相結合的方法定位出人眼，黑塊分析基於圖像的二值特徵以及人眼的幾何特徵，投影分析則基於圖像的灰度特徵進行，它對黑塊分析的結果進行補充；根據定位出人眼信息，取出人臉的二次輪廓；對人臉的二次輪廓進行標準化，獲取人臉的標準圖像。
  6. Generally speaking, the segmentation method itself could n ' t judge whether there are overlapping bubbles or not in the images ; also could n ' t split them. a concavity detection method of the overlapping bubbles, based on the projection of the object contour is proposed here ; then departing point pair is obtained by matching the concavities ; finally, the splitting curve is obtained by the departing point pair constrained based minimum mean square error ( mmse ) ellipse fitting

    一般說來，圖像分割無法判斷所獲得的氣泡區域是否存在粘連並對其進行分西安理工大學碩士學位論文離，所以本文採用對日標物的輪廓進行投影檢測來尋找氣泡粘連處的凹點，並對凹點進行配對以獲得粘連氣泡的分離點對。
