In urban areas, the reconstruction of gable-roof buildings from high-resolution synthetic aperture radar (SAR) images is more challenging compared to simple parallelepiped buildings. In this paper, an alternate iteration and matching technique is proposed for height and roof inclination angle estimation of gable-roof buildings. First, the different appearances of this building type in SAR images are...
In this article we describe a novel Adaptive particle swarm optimization (APSO) algorithm based on population diversity information. It is presented to solve the precocious convergence problem of particle swarm optimization algorithm. The APSO algorithm uses the information of the population diversity to adjust nonlinearly inertia weight. Velocity mutation factor and position interchange factor are...
Selecting suitable features is very crucial for achieving successful classification of land cover types. This paper presents a comparative study of three typical feature selection methods for the task of regional land cover classification using MODIS data. Comparison results have shown that Branch and Bound is the best for land cover classification with MODIS data, while ReliefF and mRMR achieve nearly...
