Recently, some 2D based algorithms were proposed for image classification. In this paper, we propose two-dimensional logistic regression for two-class problem. This method has an advantage of memory saving and better performance than other 2D based approaches. The experimental results show two dimensional logistic regression is superior to one dimensional logistic regression and other popular two-dimensional...
In this paper, the user identification based on face and speaker information obtained from camera and microphone for the intelligent service robot is proposed. For this purpose, we use fisherface method for face recognition. The choice of the fisherface method in this setting is motivated by its insensitivity to large variation in light direction, face pose, and facial expression. Furthermore, we...
