Face recognition based on illumination invariant;
基于光照不变量的人脸识别
The paper describes the origin of this dependence by analyzing the essential goal and current technologies of speech processing,then explains that analysis of speech variations is not an intractable problem through analysis of speech terms and their relational acoustic invariance.
接着通过对语音多变的不可避免性与声学不变量的相对性的阐述,说明语音的变化并非完全不可知,进而指出解决问题的关键在于充分认识语音变化的规律性和在处理系统中综合利用这些规律。
In this paper we first analyze the mechanism of shadow formation and the limitation of the photometric color invariants using illumination model.
本文利用光照模型分析了阴影形成的机理和光度彩色不变量的局限性,结合城市彩色航空影像的特点和实际数据的分析,推导出城市彩色航空影像中阴影区域具有色调较高的特征,并据此提出了一种简便的城市彩色航空影像阴影检测方法。
