【摘要】 眼睛定位在人脸识别检测过程中起着非常重要的作用。研究后发现,眼睛的灰度值在人脸所有的五官中是最高的,且具有一定的面积。文中针对人脸各器官的几何结构特征,结合眼睛灰度信息提出了一种新的眼睛定位算法通过对灰度图像进行垂直和水平灰度投影后,能够对人脸初步定位,然后用一个相当于瞳孔大小的方形框去搜索整张脸,当落在这个框内的黑色像素的个数达到最大时,这个框的位置就是眼睛的位置。经过实验,这种算法定位准确且定位时间短。更多还原

【Abstract】 Face recognition (F. R.) has immense applications in now the time, and the most important part in F.R. is eyes location. Eyes’ gray level is the highest facial feature than others and has some areas. So we propose a new eyes location method based on choosing eyes’ gray level information and facial features. It locates the position of the eyes by projecting gray picture perpendicularly and levelly to locate face, then using a quadrate circle quite to pupil in size to search the whole face. When the number of pixels in the circle is maximum, the position of the circle is the position of the eyes. Experiments confirm the presented method can orientate quit well in short time.更多还原
