Support vector machine (SVM) is more popular in recent years in the field of pattern recognition algorithms. SVM algorithm has good validity of the calculation, statistical robustness and stability. SVM has gradually become an important tool in the field of remote sensing image classification. Because of the similarity between the different classes in the multispectral images, the result of the classification...
An effective approach based on geometric constraint of the motion vector field is proposed to detect camera zoom operation. The approach exploits the valid motion vectors to estimate the center of focus (COF) for zoom, and then calculates the average distance from the COF to valid motion vectors to identify zoom operation. To reduce the influence of object motion, Visual attention mechanism is employed...
This paper presents a novel and efficient surface matching and visualization framework through the geodesic distance-weighted shape vector image diffusion. Based on conformal geometry, our approach can uniquely map a 3D surface to a canonical rectangular domain and encode the shape characteristics (e.g., mean curvatures and conformal factors) of the surface in the 2D domain to construct a geodesic...
