@article{(Open Science Index):https://publications.waset.org/pdf/8169, title = {A Novel Non-Uniformity Correction Algorithm Based On Non-Linear Fit}, author = {Yang Weiping and Zhang Zhilong and Zhang Yan and Chen Zengping}, country = {}, institution = {}, abstract = {Infrared focal plane arrays (IRFPA) sensors, due to their high sensitivity, high frame frequency and simple structure, have become the most prominently used detectors in military applications. However, they suffer from a common problem called the fixed pattern noise (FPN), which severely degrades image quality and limits the infrared imaging applications. Therefore, it is necessary to perform non-uniformity correction (NUC) on IR image. The algorithms of non-uniformity correction are classified into two main categories, the calibration-based and scene-based algorithms. There exist some shortcomings in both algorithms, hence a novel non-uniformity correction algorithm based on non-linear fit is proposed, which combines the advantages of the two algorithms. Experimental results show that the proposed algorithm acquires a good effect of NUC with a lower non-uniformity ratio.}, journal = {International Journal of Electronics and Communication Engineering}, volume = {6}, number = {12}, year = {2012}, pages = {1391 - 1394}, ee = {https://publications.waset.org/pdf/8169}, url = {https://publications.waset.org/vol/72}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 72, 2012}, }
