摘要:
This paper concerns the problem of video stitching automatically in a multi-camera surveillance system. Previous approaches have used multiple calibrated cameras for video mosaic in large scale monitoring application. In this work, we formulate video stitching as a multi-image registration and blending problem, and not all cameras are needed to be calibrated except a few selected master cameras. SURF is used to find matched pairs of image key points from different cameras, and then camera pose is estimated and refined. Homography matrix is employed to calculate overlapping pixels and finally implement boundary resample algorithm to blend images. The result of simulation demonstrates the efficiency of our method.

摘要:
To deal with the high dimensionality and redundancy of the online writeprint, this paper proposed an ensemble learning approach based on Multiple Probabilistic Reasoning Model. An inverse method of pseudo-random number generator is employed to construct multiple random subspaces, and then the base classifier is trained in each subspace. Finally, each classifier is aggregated to construct a strong ensemble through a combination strategy. The experiment is conducted on a real dataset, focusing on the approach's parameters, sampling rate and granularity of space dividing. The results show that the proposed method is effective and appropriate values of parameters can effectively improve the identification performance of online writeprint.
