Another kind of blur we can perform in Wand is Motion Blur. In this kind a Gaussian blur is performed in a single linear direction and it appears like image is moving in a linear direction. It takes a new angle parameter.
Syntax :
Python3
wand.image.motion_blur(radius=radius_value, sigma=sigma_value,angle=angle_value, channel="optional_channel_value")# radius should always be greater than sigma(standard deviation)Parameter :
Parameter Input Type Description radius numbers.Real the radius of the, in pixels, not counting the center pixel. sigma numbers.Real the standard deviation, in pixels angle number.Real Apply the effect along this angle. channel basestring Optional color channel to apply blur.
Image Used :
Example 1:
Python3
# import display() to show final imagefrom wand.display import display# import Image from wand.image modulefrom wand.image import Image# read file using Image functionwith Image(filename ="koala.jpeg") as img: # perform motion blur effect using motion_blur() function img.motion_blur(radius = 16, sigma = 8, angle = 90) # save final image img.save(filename ="mb_koala.jpeg") # display final image display(img) |
Output :
Example 2: increase radius, sigma and changed angle to 45.
Python3
# import display() to show final imagefrom wand.display import display# import Image from wand.image modulefrom wand.image import Image# read file using Image functionwith Image(filename ="koala.jpeg") as img: # perform motion blur effect using motion_blur() function img.motion_blur(radius = 22, sigma = 10, angle = 45) # save final image img.save(filename ="gb_koala.jpeg") # display final image display(img) |
Output :
