How to make a blurred picture clear?

The clear process of blurred image restoration is as follows:

Tools/materials: desktop Lenovo AC 128, Windows 10, PhotoshopCS20 18.

1. As shown in the figure, after opening the corresponding picture, copy the current layer.

2. The user opens the color price panel, obtains the background color with a straw, and adjusts the parameters.

3. Then, click the "Gao Fancha Reservation" option in the "filter" menu and set the data as shown below.

4. Finally, set the layer blending mode to the line light option to complete the image sharpening operation.

Clear restoration principle of blurred image

In order to solve these problems, the principle of restoring the sharpness of blurred images is mainly to restore the sharpness of images through image processing algorithms. These algorithms include image denoising, image enhancement and image restoration. Among them, image denoising is the most basic processing method. By removing the noise in the image, the image can be clearer.

Commonly used denoising algorithms include mean filtering, median filtering and Gaussian filtering. Image enhancement is to make the image clearer by enhancing the contrast and brightness of the image. The commonly used image enhancement algorithms are histogram equalization and Laplace transform.

Image restoration is a more advanced processing method, which can predict the original state of the image through mathematical model, thus restoring the clarity of the image. Common image restoration algorithms include Wiener filtering and inverse filtering.
