Secondly, the anterior segment image, which was acquired by the method of direct focal illumination, was analyzed automatically to give some physiological and pathological parameters.

然后对利用直接焦点照明法采集得到图像进行自动分析提取眼前节的各种生理、病理参数；

When acquiring the pavement image, the acquired image is hard for image segmentation and recognition because of the noise and the nonuniform background illumination.

在获取路面图像中，由于背景光照不均匀以及存在着一些路面噪声，给后来的图像分割及识别带来了一些困难。

The algorithm can be configured to maintain "constant image brightness" (which results in lower power consumption) or to maintain "constant illumination power" (which results in higher image brightness).
