lighteness meaning in Chinese

亮度

In order to solve this problem , this paper introduces a reading lamp which can change the lighteness automatically . it has a photodetector which will be put near the book to help adjusting the brightness data
即可减少手动调光的麻烦，又可以保护视力，同时，它具有稳光功能，当电源电压波动时，台灯亮度保持不变。
During image recognition , it reduces the yawp and improves the quality of the image with the technology of the median filter , it uses the method of maximum between - class variance to segment the object , then gets better effect . the algorithm is simple , and the adapted capacity is great . it doesn ’ t influence by the change between the contrast and lighteness of the image . so it applies on the real time system
在图像识别过程中,本文运用了中值滤波技术降低了噪声,提高了图像的质量,并采用了最大类间阈值分割法分割目标,得到了较好的效果,该方法计算简单,自适应性强,在一定条件下不受图像对比度与亮度变化的影响,因而在一些实时图像处理系统中得到了广泛的应用。
