There is a well-finished project on GitHub, rembg
Simple and practical tool to delete image background/cutout
can remove the background of the picture and cut out the main content.
how to use?
1. Installation
CPU support:
pip install rembg
GPU support:
pip install rembg[gpu]
There are a lot of things to install, and you can use it after the installation is complete
2. use
There are many ways to use it; you can type a line of command to cut out the image directly, you can also deploy it to the server and use the browser to cut out the image, you can also write py code to cut out the image, you can also use docker, etc.
2.1 Using the command line
2.1.1. In the command line, switch to the virtual environment used. My virtual environment is named py310
conda activate py310
2.1.2. Start cutout
# 1、扣本地的图
rembg i path/to/input.png path/to/output.png
# 2、扣网上的图
curl -s http://input.png | rembg i > output.png
# 3、扣整个文件夹的图
rembg p path/to/input path/to/output
Before cutout: (picture from Baidu)
After cutout:
2.2 Use as a service
That is to say, it can be deployed on your own cloud server, and you can cut out pictures anytime, anywhere for the entire webpage or app.
2.2.1 Official web version
# 在虚拟环境中，敲以下命令：
rembg s
The service address will be prompted: http://0.0.0.0:5000
Note that this address is not opened directly, and a docs must be added later, that is: http://0.0.0.0:5000/docs The
get method is applicable to URL addresses on the Internet
The post method is suitable for file streams, here we use the post method
TenTry it out
upload image
point execute
Get the cutout result:
2.2.2 Make your own website
Create a new html file and add the following code:
<form
action="http://http://0.0.0.0:5000"
method="post"
enctype="multipart/form-data"
>
<input type="file" name="file" />
<input type="submit" value="upload" />
</form>
open html file
After uploading the file in the browser, the image will be cut out automatically
2.3 Use as a python library
2.3.1 In the form of file stream
Input and output as bytes
from rembg import remove
input_path = 'input.png'
output_path = 'output.png'
with open(input_path, 'rb') as i:
with open(output_path, 'wb') as o:
input = i.read()
output = remove(input)
o.write(output)
2.3.2 Using PIL images
Input and output as a PIL image
from rembg import remove
from PIL import Image
input_path = 'input.png'
output_path = 'output.png'
input = Image.open(input_path)
output = remove(input)
output.save(output_path)
2.3.3 Even use numpy array
Input and output as a numpy array
from rembg import remove
import cv2
input_path = 'input.png'
output_path = 'output.png'
input = cv2.imread(input_path)
output = remove(input)
cv2.imwrite(output_path, output)
2.4 Use in docker mode (try this later)
docker run -p 5000:5000 danielgatis/rembg s
After writing so much, I ask a soul question:
As a programmer, what is the use of cutout? I usually use it when I make ppt. However, it seems that many softwares have built-in cutout function, so everyone interested in the rembg project can just play around.
For example:
Figure 1 is the appearance of ppt without cutout; Figure 2 is the appearance of ppt after cutout. Figure 2 has less occlusion to the original ppt, and there is no sense of disobedience.
