摘  要:霧霾等天氣下,光線在傳輸過程中受到反射和散射,降低圖像質(zhì)量。根據(jù)大氣散射模型,提出一種在HSV空間的霧天彩色圖像增強方法,該方法使用一種適應性更廣的亮度增強函數(shù),并通過圖像飽和度的指數(shù)調(diào)整。實驗結(jié)果表明該方法有效地改善圖像的視覺效果和圖像色彩的真實效果。

Abstract: In haze and other weather conditions, light is reflected and scattered in the process of transmission, which reduces the image quality. According to the atmospheric scattering model, a foggy color image enhancement method in HSV space is proposed, this method uses a more adaptive luminance enhancement function and adjusts the image saturation exponentially. The experimental results show that this method can effectively improve the visual effect of the image and the real effect of the image color.

霧天時,彌漫在空中的霧氣模糊了人們的視線,使得景物的能見度大幅降低,圖像中蘊含的許多特征都被覆蓋或模糊。(剩余5606字)
