Intelligent correction algorithm for chromatic aberration of led spectral image under multiple-beam interference

摘要

The traditional color correction algorithm has the influence of multiple-beam interference. It leads to the effect of unsatisfactory visual correction. This paper focuses on an algorithm for intelligent correction of chromatic aberration in LED spectral image under multiple-beam interference. Firstly, the method carried out minimum noise separation for LED spectral image under multiple-beam interference. Secondly, it characterized by combining spectrum and image in LED spectral spectrum. It extracted characteristics of LED spectral imagefromimage and spectrum. Then, it calculated the tristimulus values of surface features, the pixelvalue of each band and color correction coefficient of each band. Finally, it used multi-point color correction method to realize intelligent correction of chromatic aberration in LED spectral image under multiple-beam interference. Experimental result shows that the proposed algorithm can eliminate multiple-beam interference. It obtains the chromatic aberration correction result according with visual effect.
