Firstly, a class of affine nonlinear systems are considered. The single-layered neural networks are used to approximate the nonlinear functions of the systems. Stable adaptive control algorithms are presented based on system states feedback and system output feedback respectively. The boundary of the tracking error is guaranteed. Then, by using the technique of input-output linearization, the stable adaptive control method for general nonlinear systems is proposed. Finally, the effectiveness of the proposed adaptive control algorithms are verified through the simulation researches for the control of robot manipulator.

The heart of this algorithm is to track at least four fiducial points from frame to frame that construct the affine frame, and thus the occlusion contours between virtual and real objects can be reconstructed and reprojected.

The heart of this algorithm is to track at least four fiducial points from frame to frame that construct the affine frame, thus the occlusion contours between virtual and real objects can be reconstructed and reprojected. Further, each contour is labeled as being "behind" or "in front of" in the first two frames, depending on whether it is in front of or behind the virtual object, so the occlusion is resolved.
该算法的核心是在每一帧图像中追踪至少四个基准点,构成仿射基,进而对虚拟物体与真实物体之间的遮挡轮廓进行重建和重投影,且在前两帧图像中交互指定这些阻挡轮廓相对于虚拟物体的前后位置,从而解决了扩充现实的阻挡问题。
