From Grayscale to Color: Quaternion Linear Regression for Color Face Recognition
Linear regression has shown an effective tool for face recognition in recent years. Most existing linear regression based methods are devised for grayscale image based face recognition and fail to exploit the color information of color face images. To extend linear regression for color images, we pr...
