Abstract According to the characteristics of gray image, the histogram specification algorithm based on 3-spline interpolation was introduced in this article, which obtained image enhancement in continuous casting sheet billet image. Based on the theory of histogram specification algorithm, the improved algorithm adopts 3-spline interpolation to fit the original histogram image, and uses the fitting function to process the histogram specification. The comparative experimental analysis of the improved histogram specification algorithm and the traditional histogram specification algorithm based on Gaussian probability density function (Gaussian PDF) examines and certifies the effectiveness and practicability of the modified algorithm.
