为提高图像的视觉质量,需要对图像进行对比度增强处理.从研究图像增强的空域法人手,分析了Retinex理论的相关方法.考虑到基于Retinex理论现有算法的不足,提出了基于亮度分量的处理方法,并用IIR实现高斯函数的运算.仿真结果表明,改进后的方法在完成图像增强的同时,能避免灰度化,保持色彩恒常,并加快处理速度.
為提高圖像的視覺質量,需要對圖像進行對比度增彊處理.從研究圖像增彊的空域法人手,分析瞭Retinex理論的相關方法.攷慮到基于Retinex理論現有算法的不足,提齣瞭基于亮度分量的處理方法,併用IIR實現高斯函數的運算.倣真結果錶明,改進後的方法在完成圖像增彊的同時,能避免灰度化,保持色綵恆常,併加快處理速度.

Contrast enhancement process is needed in the images in order to improve its visual quality. Starting from the point of spatial methods of image enhancement, Retinex-related methods are analyzed. Considering the defects of the Retinex algorithm, processing method based on luminance and Guassian function using IIR implementation are proposed in this paper. The simulation results prove that these measures can not only enhance the images, and can prevent grayish, keep color constancy and accelerate the processing speed.
