Examples
- At first this paper pointed out a technique of solution about cylinder ' s parameter equation , and also introduced a technique of solution on the parameter equation of sapce curve ' s projection on the flat surface , which made application more convenient
摘要首先给出了柱面参数方程的求法，从而也给出了空间曲线在平面上的投影曲线参数方程的求法，使应用更加方便。 - While face detection and localization , we used a method of locating eye features in facial images based on gray - level projection and edge detection . first , the left and right boundaries of face is localized with vertical gray - level projection
在人脸检测与定位中，本文采用了一种基于灰度投影曲线和边缘检测进行人眼定位的算法，首先利用原图的垂直灰度投影曲线确定人脸的左右边界。 - This algorithmcarries on two values pictures processing in the differencefoundation , according to the human body statistical characteristic , proposed through the judgement projection curve second time derivativesize , determines the person face boundary the method
该算法在差分的基础上进行二值图像处理，根据人体的统计特征，提出通过判断投影曲线的二阶导数大小，来确定人脸边界的方法。 - By the reason of characteristic on statistics of images , we gave a face searching and locating algorithm based on the second derivatives operator . we obtain the position of face by calculating the change of projection curve using the second operator
该方法计算人脸在两个投影方向上的统计特征，使用二阶微商算子估计投影曲线斜率的变化，进而找出人脸的外接矩形，判断头部在图象中的位置。
