1·At the same time, the array of three values simplifies the complexity in the image, so even if a video is of poor quality or a different hue, the information about its relative luminance is retained.
同时,三种数值的排列简化了图片的复杂性,所以即使一个视频质量差或色相不一,关于视频的相对亮度信息还能保留。
2·The research on the appraisal to the road lighting quality should use luminance standard and small target visibility level which are more conform to the human eye visual characteristic.
研究道路照明应以更加符合人眼视觉特性的亮度指标和可见度指标对道路照明质量进行评价。
3·The functions can be realized by the system, for example, display in same time about image, test frame, luminance value and set parameter, and wide-range measure, etc.
该系统的建立,可实现图像、测试框、亮度值、设定参数的同屏显示及宽量程测量等多种功能。
4·The proposed method determines the motion activity and visual content change of the MPEG compressed video by using the luminance DCT DC value, macroblock type and motion vector.
本文算法利用亮度DCT DC值、宏块类型和运动向量来确定MPEG压缩视频中运动活动和视觉内容变化。
5·As to sea image, the variance feature of region of interest and the luminance contrast feature between target and background are used to fusion recognition.
对于海面图像,分别采用感兴趣舰船目标区域的方差值、目标和背景亮度对比度这两个特征对目标进行融合识别。
