Preface

I've been doing it some time ago golang, Pay little attention to some open source projects . Happened to meet one , You can make blurred photos or videos clear , Projects that can be processed in excess .

project github Address ：GitHub - xinntao/Real-ESRGAN: Real-ESRGAN aims at developing Practical Algorithms for General Image/Video Restoration.

Take a look at the renderings given by the project .

It can be seen that the model also has a good effect on animation illustration .

The project also lists some similar projects , You can see GFPGAN It's on the list . 

If you're right GFPGAN If you are also interested , You can refer to another article of mine to understand .

How to restore a blurred photo face to clarity ,GFPGAN Machine learning open source projects use | machine learning _ Swordsman a Liang _ALiang The blog of -CSDN Blog

This article mainly makes some simple use of this project .

Download the execution file

You can directly download the execution program of the project to run and see .

If you can't download , You can use my link below .

Test use

The unzipped directory structure is shown in the figure below .

We can go through README file , Learn how to use .

Picture test repair super score

Let's take a look at the pictures provided and their resolution .

open CMD Go to the folder location .

Execute the order as follows ：

realesrgan-ncnn-vulkan.exe -i input.jpg -o output.png -n realesr-animevideov3

The results are as follows , You can see the specific progress .

Finally, the processed image is generated output.png, Let's take a look at the generated image and its resolution .

It can be seen that both the definition and resolution have been improved .

Video needs to be used ffmpeg Split the video , If not ffmpeg Of , Please refer to my article .

windows ffmpeg Installation and deployment _ Swordsman a Liang _ALiang The blog of -CSDN Blog _ffmpeg windows install

First create two directories to store split and processed picture frames .

First, let's take a look at the provided video picture and its resolution .

according to README The instructions in it , There are three steps to deal with .

step1

ffmpeg -i onepiece_demo.mp4 -qscale:v 1 -qmin 1 -qmax 1 -vsync 0 tmp_frames/frame%08d.jpg

After execution tmp_frames The directory produces split picture frames .

step2

realesrgan-ncnn-vulkan.exe -i tmp_frames -o out_frames -n realesr-animevideov3 -s 2 -f jpg

This step will take a long time .

step3

ffmpeg -i out_frames/frame%08d.jpg -i onepiece_demo.mp4 -map 0:v:0 -map 1:a:0 -c:a copy -c:v libx264 -r 23.98 -pix_fmt yuv420p output_w_audio.mp4

take out_frames The pictures in are compressed into video , Take a look at the final video quality .

It can be seen that the definition and resolution have also been greatly improved .

summary

What attracts me more about this project is its support for animation illustrations , There are special models .

Recently, I am learning the first principle , I thought it over . In fact, we have two methods, induction and deduction , Just subconsciously choose the first . Still stand out of things , Adjust your way of thinking , To have more vision .
