Neural network techniques have been widely applied to areas of such as data mining, information integration and grid computing. This paper proposes a new learning algorithm based on trust region optimization theory. In the paper, the Dogleg-algorithm to obtain the valid trust region steps is presented, and a self-adjustable method with variable coefficients is given to resolve the problem of oscillatory...
It is very important to study non-uniformity correction algorithm in infrared focal plane array (IRFPA). In order to improve the convergence speed and non-stability in traditional neural network non-uniformity correction algorithm, a new scene-based non-uniformity correction algorithm for IRFPA was designed in this paper. The algorithm firstly arrange a pixelpsilas gray value and its around eight...
