摘要：在对耳朵图像进行研究后，提出了一种基于灰度投影函数的耳朵图像定位方法。首先利用灰度投影曲线实现耳朵左右边界的粗定位，通过边缘提取和阈值分割进行耳朵上界和边界二次定位，最后由计算得到耳朵的下边界，进而最终定位耳朵区域。

Abstract: An algorithm for ears location is presented based on gray projection method after studying the image of the ear. First, by utilizing the gray projection curve of the image, this paper can locate the left and right boundary of the ear’s area. The edge detection and threshold fix on the up boundary of the ear and realize the second location. At last, the down boundary can be calculated. And then, the ear’s area will be located finally.
Key words:Ear;Gray projection;Location
