Temporal tie points have been manually selected for sea ice concentration retrieval based on the linear combination relationship between the open water and the complete ice coverage pixel. In this paper, the multichannel information has been exploited using the constrained least-squares linear unmixing algorithm from AMSR-E multi-channels brightness temperature. Snow depth can be obtained from the...
It's still in search that how to apply SVM in muti-classify. Directed Acyclic Graph is easier to be computed and has better learning effect than other arithmetic. Experimental platform is used to simulate typical faults of circumrotate machines. Based on the frequency domain feature, energy eigenvector of frequency domain is presented using wavelet packet analysis method. DAGSVM is applied in classification,...
In reality, the paper money number recognition is significant, which can effectively prevent the illegal trade of paper money. First, this paper makes pretreatment to the paper money, and then for the rapidity and accuracy requirements, a new identification method is presented which based on intersection change and the distance difference between the two points of the character on the special location...
To solve the problem of slow convergence speed of the standard genetic algorithm (SGA), the strategy of adaptively changing the search area is used to reduce the search area progressively in this paper. The tactics of concerted evolution among multiple populations is proposed aimed at the deficiency of easily plunging into a local optimal solution of SGA. Distant hybridization strategy and a new method...
Due to the existence of systematic bias in the measurements, inter-chip normalization is required before integrated data analysis of multiple microarray datasets. Current inter-chip normalization methods rely on some assumptions, which can rarely be verified by experiments, such as the invariant expression level of housekeeping genes or the stability of statistical data distribution. In this paper,...
It has been shown that the fuzzy integral is an effective tool for the fusion of multiple classifiers. Of primary importance in the development of the system is the choice of the measure which embodies the importance of subsets of classifiers. In this paper we propose a method for a dynamic fuzzy measure which will change following the pattern to be classified (data dependent). This method uses the...
An improved algorithm for computing geodetic coordinates from Cartesian coordinates is presented. The algorithm solves a quartic equation of the Lagrange parameter using Newton-Raphson (NR) method. A initial guess is given weightily that works rigorously for most points except in a small near-geocenter region. Numerical experiments and comparisons with some other methods show that the new algorithm...
