This paper analyzes the observability of estimating simultaneously the initial position and velocity of a constant velocity source by two fixed receivers using TDOA measurements observed many a time. From the geometrical means of vector operations, it arrives at the conclusion that the conditions are similar to those in the general source localization by multi-receivers using TDOA. Then the Cramer-Rao...
The shadows are regarded as obstacles in remote sensing image analysis. With high-resolution remote sensing images developed, especially in urban area, shadow detection plays a much more important role in many applications. This paper presents a novel vision-based shadow detection method. The shadow areas are usually much darker than non-shadow areas visually in high resolution images. In our method,...
Generalization ability is an important issue in gender classification. In this paper a gender classifier based on Fuzzy SVM (FSVM) is developed to improve the generalization ability. The fuzzy membership used in FSVM indicates the relativity of one personpsilas face with female/male faces set. This paper proposes a novel method of generating fuzzy membership function automatically based on Learning...
