轮廓形的

After ten or twenty minutes of sitting without using my flashlight, my eyes adapted to the dark and I could make out forms against the brown-black sand: the beach plum and coconut palm silhouettes in back, the flicker of the surf in front, sometimes even the shadowy outline of a trailing railroad vine or the scurry of a ghost crab at my feet.

关了手电筒，坐上十来二十分钟，眼睛便已适应了黑暗。我可以从深棕色的沙滩上辨出一片轮廓来：黑色的海滩李和椰子树的轮廓，面前海浪的摇晃，偶尔还有蔓延的马鞍藤的错影斑形和脚边矶蟹的匆匆横行。

It modified some terms of the initial formula, which made the snake model not only precisely extract the edge of the protruding object in images but also approach to the concave part of the edge. It introduced exterior sanction energy, which could adaptively change its value to enlarge suction, so that control points could quickly constringe to the real contour without relying on the initial contour. Combined with pattern matching, this new method could increase the precision of transferring the result of edge extraction from one slice to another.

通过调整原始公式的一些参数使得该模型不但能精确地提取图像中的凸形物体的边缘，而且能够接近边缘的凹陷处；引入自适应改变大小的外部约束能量来增大外能的吸引范围，使控制点能够不依赖于初始轮廓而快速地收敛到目标的真实轮廓；结合匹配技术，提高边缘提取结果层间传递的精度。

Some applications of the Bezier curve to computer graphics are introduced in this paper. These include generating flowered patterns approximate drawing of profile of machine parts, designing the shape of industrial products with free curve, making three-dimensional picture of ratators with the Bezier curve as the generating line and plotting charts by smoothing out the graphs of discrete data of scientific experiments.
