Search for optimal infrared projector nonuniformity correction procedures II

摘要

The one-dimensional nonuniformity scene generatic method presented in an eariler paper is extended to the two-dimensional case of real interest. It is shown that the algorithm applied to the one-dimensional case is extendable although its speed of convergence is reduced in two dimensions because fo the increased mixing of nonuniformity information. Alternative nonuniformity correction agorithms are developed and compared and it is demonstrated that by utilizing an estimate of the point spread function the scene correction efficiency can be substantially improved.
