Support Vector Machine (SVM) is used to classify hyperspectral remote sensing image in this paper. Radial Basis Function (RBF)
which is most widely used
is chosen as the kernel function of SVM. Selection of kernel function parameter is a pivotal factor which influences the performance of SVM. For this reason
Particle Swarm Optimization (PSO) is provided to get a better result. In order to improve the optimization efficiency of kernel function parameter
firstly larger steps of grid search method is used to find the appropriate rang of parameter. Since the PSO tends to be trapped into local optimal solutions
a weight and mutation particle swam optimization algorithm was proposed
in which the weight dynamically changes with a liner rule and the global best particle mutates per iteration to optimize the parameters of RBF-SVM. At last
a 220-bands hyperspectral remote sensing image of AVIRIS is taken as an experiment
which demonstrates that the method this paper proposed is an effective way to search the SVM parameters and is available in improving the performance of SVM classifiers. 2012 IEEE.

Although animated meshes are frequently used in numerous domains
only few works have been proposed until now for simplifying such data. In this paper
we propose a new method for generating progressive animated models based on local feature analysis and deformation area preservation. We propose the use of solid angle and height value for a non-hyperbolic vertex to define the local feature parameter. This local factor is embedded to the vertex quadric error matrix when calculating the edge collapse cost. In order to preserve the areas with large deformation
we add deformation degree weight to the aggregated quadric errors when computing the unified edge contraction sequence. Finally
a mesh optimization process is proposed to further reduce the geometric distortion for each frame. Our approach is fast
easy to implement
and as a result good quality dynamic approximations with well-preserved fine details can be generated at any given frame. 2010 IEEE.

In order to reduce the size and weight of the gimbal in a traditional stable platform and correct the disadvantage in size of the payload
the paper first improves the gimbal which is an important component of a stable photoelectric platform
that also is an important factor in affecting the size and weight of a stability platform. In this paper
a closed-form solution of 3-DOF manipulator is designed according mechanical arm design principles. This manipulator is formed by a three joint axes whose extended line is intersected at one point. A standard orthogonal coordinate system is set up for each rod in the manipulator. And then
rotation transformation matrix expression is obtained. At last in this paper
the manipulator arm-shaped method for solving solutions is description
and also
each parameter of the gimbal is calculated when the photoelectric detection devices at bottom reach the expected position. Test results show that the photoelectric stability platform with gimbal we designed is smaller
lighter and simpler than that traditional. Also
the packaging and size of the photoelectric will not be affected with this open structure. 2010 IEEE.

In this paper
we propose a new method to approximate deforming models based on torsion detection. We propose the use of surface torsion to represent local features on the original model
and consider it as an additional weight factor when calculating the edge contraction cost during the simplification process. The approximations of the original deforming models are generated progressively from the first frame to the last one. Based on the edge contraction sequence in the previous frame
the contraction order in the current frame is adjusted according to the deformation degree. Our approach is fast
easy to implement
and as a result good quality approximations with well-preserved fine details can be generated at any given frame. 2010 IEEE.
