摘　　要：在图像增强技术中,现有的图像增强算法在对图像进行增强时,总是伴随着原图像亮度的丢失和过度增强效果。提出一种改进的图像增强算法,该方法解决了传统图像增强过程中造成的过度增强、局部过度不自然、原始图像亮度降质的问题。实验结果证明,基于峰值信噪比的改进的图像增强方法优于现有的算法,并且该算法可以在对图像增强的基础上有效的维持原始图像的亮度。In the image enhancement technology,the existing image enhancement algorithm is always accompanied by the loss of the original image brightness and excessive enhancement effect when the image is enhanced. Therefore,an improved image enhancement algorithm is proposed,which solves the problem that the traditional image enhancement process is over-enhanced,the local over-unnatural,the original image brightness is degraded. The experimental results show that the improved image enhancement method based on peak signal to noise ratio is superior to the existing algorithm,and the algorithm can effectively maintain the brightness of the original image on the basis of image enhancement.
