This paper also notes that the super parameters of detail enhancement methods have a great impact on the results of image enhancement [12]. Generally, the fusion decomposition of the above filtering can be expressed as follows: Here, represents the observed image, represents the edge-preserving filtering operation, represents the detail layer of the image, represents an important parameter, the main function of this parameter is to control the expansion of the detail layer, and represents the image after the above enhancement [25]. The image enhancement method based on edge-preserving filtering and decomposition model selectively highlights the feature areas in the image according to specific needs without considering the image degradation process and suppresses unimportant features so that the enhanced image is more accurate than the original image suitable for specific applications [24]. Contrast is an important factor in any subjective evaluation of image quality. The enhancement does not raise the inbuilt information content of the data other than it increases the dynamic range of the selected facial appearance as a result that they can be detected. desktop applications, Dynamsoft Barcode Therefore, this paper proposes an image enhancement network based on deep learning, which can directly convert the original image into a color image [26].
