This paper presents a novel approach to scribblebased image colorization. In the work reported here we have explored how to exploit the textural information to improve this process. For every scribbled image we extract the most discriminative features using linear discriminant analysis (LDA). After that, the whole image is projected onto a discriminative textural feature space. Our main contribution lies in propagating the color in the feature space domain rather than using the luminance channel. The presented experimental validation confirms the importance of using textural information and show that our method significantly improves the obtained colorization results.

This paper presents a novel robot that combines flying and ground moving capabilities. In doing so, new applications areas for robotics are created in which these two capabilities are needed to perform the tasks. The flying motion will be based on the concept of flying mechanism of the quadrotor. Wheeled mobile platform is combined to the flying mechanism to facilitate ground motion. Transformation mechanism was developed to transform the robot from the ground motion configuration to the flying motion configuration and vice versa. The idea of this mechanism is to close the rotors' arms of the quadrotor and put them in the vertical position when the robot is used for ground motion. This is necessary to enable navigation through narrow spaces. A manipulator with 3-DOF has been added to handle objects during ground motion. After defining the appropriate mechanisms and the basic structure of the robot, geometrical dimensions and material selection of each part are decided. Then, CAD model is developed using SolidWorks, and an iterative process has been carried out to enhance and develop the robot structure and the transformation mechanism. The CAD model was tested using the finite element method in ANSYS14 where static structural study is performed. Finally, motors, sensors and control system hardware were selected for this robot. The analysis indicates the feasibility of the proposed robot.
In this paper, we consider the problem of noncausal identification of nonstationary, linear stochastic systems, i.e., identification based on prerecorded input/output data. We show how several competing weighted (wind...
