摘　　要：当前Retinex算法对激光图像超分辨增强时,存在对噪声抑制效果差,图像增强后颜色畸变等缺陷,为了获得更优的激光图像超分辨增强效果,提出了改进多尺度Retinex的激光图像超分辨增强方法。首先对多尺度Retinex算法进行改进,并采用其对激光图像进行增强处理,然后为了避免增强后图像的颜色与原图像差异显著,对增强后图像进行细节补偿和颜色校正,最后进行了激光图像超分辨增强的仿真实验结果,结果表明,本方法增强后的激光图像细节更加清晰,主观视觉效果好,而且图像的对比度接近9,相关系数超过0.95,信息熵值大于0.9,获得了理想的激光图像超分辨增强效果。The current Retinex algorithm has some defects in laser image super-resolution enhancement,such as poor noise suppression and color distortion after image enhancement.In order to obtain better laser image super-resolution enhancement effect,an improved multi-scale Retinex laser image super-resolution enhancement method is proposed.Firstly,the multi-scale Retinex algorithm is improved and used to enhance the laser image.Then,in order to avoid the significant difference between the color of the enhanced image and the original image,the details of the enhanced image are compensated and color corrected.Finally,the simulation results of the laser image super-resolution enhancement are carried out.The results show that the details of the enhanced laser image are clearer,the subjective visual effect is good,and the contrast of the image is close to 9.The correlation coefficient is more than 0.95,and the value of information entropy is more than 0.9.and the ideal laser image enhancement effect is obtained.
