Fast generate blur image.
Project description
Blur Generator
This tool is for generating blur on images.
There are 3 types of blur modes of motion
, lens
, or gaussian
.
We can use the results on model training or something else.
You can find a simply use case with deep learning in https://github.com/NatLee/simply-blur-detector
Installation
pip install blurgenerator
Check it on Pypi.

Example and Result
Common use
- Original image
Usage
- Motion blur
blurgenerator --type motion --input ./doc/test.png --output ./doc/motion.png
import cv2
from blurgenerator import motion_blur
img = cv2.imread('test.png')
result = motion_blur(img, size=100, angle=30)
cv2.imwrite('./output.png', result)
- Lens blur
blurgenerator --type lens --input ./doc/test.png --output ./doc/lens.png
import cv2
from blurgenerator import lens_blur
img = cv2.imread('test.png')
result = lens_blur(img, radius=5, components=4, exposure_gamma=2)
cv2.imwrite('./output.png', result)
- Gaussian blur
blurgenerator --type gaussian --input ./doc/test.png --output ./doc/gaussian.png
import cv2
from blurgenerator import gaussian_blur
img = cv2.imread('test.png')
result = gaussian_blur(img, 100)
cv2.imwrite('./output.png', result)
With depth map
Feature from this issue.
- Original image
- Depth map
Usage
- Motion blur with depth map
blurgenerator --input .\doc\depth-test.jpg --type motion --input_depth_map .\doc\depth-map-test.png --depth_num_layers 5 --depth_min_blur 1 --depth_max_blur 50 --output .\doc\depth-motion-output.png
import cv2
from blurgenerator import motion_blur_with_depth_map
img = cv2.imread('test.jpg')
depth_img = cv2.imread('test-depth.png')
result = motion_blur_with_depth_map(
img,
depth_map=depth_img,
angle=30,
num_layers=10,
min_blur=1,
max_blur=50
)
cv2.imwrite('./output.png', result)
- Lens blur with depth map
blurgenerator --input .\doc\depth-test.jpg --type lens --input_depth_map .\doc\depth-map-test.png --depth_num_layers 3 --depth_min_blur 1 --depth_max_blur 50 --output .\doc\depth-lens-output.png
import cv2
from blurgenerator import lens_blur_with_depth_map
img = cv2.imread('test.jpg')
depth_img = cv2.imread('test-depth.png')
result = lens_blur_with_depth_map(
img,
depth_map=depth_img,
components=5,
exposure_gamma=5,
num_layers=10,
min_blur=1,
max_blur=50
)
cv2.imwrite('./output.png', result)
- Gaussian blur with depth map
blurgenerator --input .\doc\depth-test.jpg --type gaussian --input_depth_map .\doc\depth-map-test.png --depth_num_layers 3 --depth_min_blur 1 --depth_max_blur 50 --output .\doc\depth-gaussian-output.png
import cv2
from blurgenerator import gaussian_blur_with_depth_map
img = cv2.imread('test.jpg')
depth_img = cv2.imread('test-depth.png')
result = gaussian_blur_with_depth_map(
img,
depth_map=depth_img,
sigma=5,
num_layers=10,
min_blur=1,
max_blur=50
)
cv2.imwrite('./output.png', result)
