摘　　要：针对Deng算法对噪声比较敏感,提出了一种自适应图像增强算法。利用Deng算法的基本原理,结合人眼的视觉特性自适应地生成算法的参数,这样既保留了原Deng算法实现容易、运算速度快等特点,还对噪声具有一定的抑制作用。通过实验比较,所提算法能够自适应地生成算法的参数,并在保持了Deng算法原有的容易实现的优点的基础上,提高了算法在抑制噪声方面的性能。For the sensitivity of Deng algorithm to noise, an adaptive image enhancement algorithm is proposed. According to the human visual properties, the algorithm uses the basic principle of the Deng algorithm to get automatic parameters of method adaptively. It can not only keep the original advantages such as easy realization, quick calculation, but also play a certain role in restraining noise. By comparing the result of adaptive image enhancement algorithm and that of other image enhancement algorithm, the adaptive image enhancement algorithm can get automatic parameters of method adaptively. Besides the easy realization of original Deng algorithm, it can improve the performance in restraining noise.
