一种SLIP模型的图像增强新算法简

New image enhancement algorithm based on the SLIP model

Image enhancement technology plays an important role in human life, social production, etc. This paper presents a new algorithm for image enhancement based on the SLIP (Symmetric Logarithmic Image Processing) model. Firstly, we get the SLIP image enhancement algorithm about image gray values based on the analysis of the existing logarithmic image enhancement algorithm. Then the SLIP image enhancement algorithm is simplified to the simple mathematical operation using the vector operation of the SLIP model. The proposed algorithm can enhance the image not only with the mode of the transmitted light image but also with the mode of the reflected light image. By means of subjective evaluation and EMEE objective evaluation, experimental results show that the proposed algorithm can enhance the image detail and improve the overall image contrast. Meanwhile, the algorithm overcomes the disadvantage that LIP image enhancement algorithm cannot enhance the images with the mode of the reflected light image.
