Python – Edge extraction using pgmagick library

Edge Extraction is technique to highlight the edges present in an image. Edge extraction is used for data extraction used in computer vision for feature detection and feature extraction.

Applications of Edge Extraction –
1. Medical Sciences
2. Fingerprint Scanning
3. Computer/Machine Vision
4. License plate Detection
5. Road Mapping
6. Text Detection

For eg:

Let’s see how we can do this in Python using pgmagick library.
Code :

Python3

# importing module

from pgmagick.api import Image
 
img = Image('koala.jpeg')

img.edge(1)

img.write('edge_koala.jpeg')

Input Image:

Output Image:
