一种自适应分数阶偏微分图像增强模型
An adaptive fractional-order partial differential image enhancement model
摘要
Abstract
Aiming at the shortcoming that the conventional adaptive image enhancement algorithms based on fractional-order partial differential equations have not good enhance performance on the dark texture region,taking into account the different sensitivity of the human eye to the light sensation,the impact of brightness on vision is combined with the conventional adaptive image enhancement algorithms based on fractional-order partial differential equations.A new adaptive fractional-order partial differential image enhancement model is established by using the gradient and gray value as parameters,which improves the shortcoming of the previous model in enhancing the dark region image.The average gradient of the enhanced image is increased significantly and the image's visual effect is improved superiorly,which shows that the proposed algorithm has some validity.关键词
