中文摘要
该提案将开发基于约束优化的算法,用于消除或锐化恒星场强度,并将通过分析和比较研究来评估这些新算法的性能。这种方法的新颖之处在于使用了1p拟范数(P1)来度量优化约束下的图像稀疏性(S)。
英文摘要
This proposal will develop algorithms, based on constrained optimization, for removing blur from or sharpening star field intensity, and will evaluate the performance of these new algorithms through analytical and comparative studies. The novelty of this approach lies in the use of the 1p quasinorm (p 1) for measuring image sparseness in the optimization constraint(s).
