In the real-word matching, deformation, outliers and other emerging variations are inseparable conditions which make matching increasingly difficult. One way to solve this challenging problem is raising an effective graph matching method which is flexible to non-rigid objects. As a good structure representation, graph can nicely describe objects with meaningful information. Meanwhile, feature pooling...
In recent years, the local feature descriptor called SHOT (Signature of Histograms of OrienTations) has achieved excellent performance in 3D vision. However, there still exists room for improvement: on the one hand, the convexity and concavity information is still ambiguous; on the other hand, it is not consistent and unique enough for constructing histograms with just angle information between normals...
Video stabilization enhances video quality by stabilizing unstable motion. This paper proposes a new video stabilization method that simultaneously factors and smooths motion trajectories. We model the trajectories with a time-variant local subspace constraint. Every column of the trajectory matrix is factored and smoothed in separate local subspace. This model makes our method more flexible and accurate...
