A geometrical optics approximation method for sphere (called Gom) is developed to compute its absorption and scattering cross sections. And it is applied to calculate absorption coefficients, scattering coefficients and phase function of electromagnetic radiation by large fogdrops. The shapes of fogdrops are assumed to be spherical. Comparison between the(More)
As traditional visual tracking algorithms based on co-training framework are characterized by poor robustness in numerous real-time scenarios, a robust visual tracking algorithm based on structural multi-scale features adaptive fusion in co-training is thereby proposed. In order to achieve a comprehensive representation, we select structural multi-scale(More)
