Using statistical characteristics of gradient phases for robust face recognition under illumination variations
Gradient phase, which is treated as an illumination insensitive measure, is an important feature for visual detection and recognition applications, especially under illumination variations. However, fewer statistical characteristics of the gradient phase have been reported till now. First, the stati...
