Stereo matching is the key issue of stereo vision. In the literature, most of the stereo matching algorithms have been limited to gray level images. In this paper, we propose a new color stereo matching approach based on self-organization neural networks. For the real images we propose a segmentation method to deal with the initial similarity map. The final similarity map is established by taking logical AND calculation of different color feature similarities so as to make full use of the color information. Experimental results have shown that the quality of the stereo matching can be considerably improved by using appropriate color matching algorithm comparing with the conventional gray value algorithm.

The feasible trajectory generation method for the systems with flat outputs by using low order polynominal may result the degradation of the control performance. In this paper, we propose a method of generating the flat outputs trajectories by using the piecewise smooth functions. Moreover, we optimize these trajectories to improve the control performance of the system. We apply our method to the attitude control of the underactuated axisymmetric spacecraft and examine the effectiveness by numerical simulation.

Stereo vision is a passive method of obtaining depth information of visible surface by measuring disparity of corresponding points in left and right stereo images. Stereo matching, which belongs to ill-posed problems, is the key issue of stereo vision. In the literature, almost all matching techniques only use gray-scale images. The color information is usually neglected, but undoubtedly it may be of great use in helping robot stereo systems perform better. In this paper, we use two layered self-organization neural network model to simulate the competitive and cooperative interaction of binocular neurons. We propose a special similarity function as initial input to make full use of the color information. In RGB color space, the similarity map is established by taking logical AND calculation of red, green and blue color value similarity. In stereo matching experiment, we first consider color random-dot stereogram for stereo correspondence. Then we take real image experiments by means of different color stereo matching approaches. Experiments results have shown that the quality and convergence speed of the stereo matching can be efficiently improved by using appropriate color matching algorithm comparing with the conventional grey value algorithm.
