Morphological edge detection or object's boundary detection using erosion and dialation in OpenCV python

Last update: Nov 25, 2022

Overview

Morphologycal-edge-detection-using-erosion-and-dialation

the task is to detect object boundary using erosion or dialation .
Here, use the kernel or structure element such as 3x3
1 1 1
1 1 1
1 1 1

if initial binary image is A and after erosion we get B
then , boundary = A - B

for dialation ,
boundary = B - A

input image

erosion output

boundary detection from erosion

dialation output

boundary detection from dialation

Intruder detection systems are common place now, and readily available in industry, but how do they work? They must detect people and large animals, but not generate false alarms in the presence of small animals, changes in lighting, environmental motion such as trees, or melting snow. To work correctly, the system must learn the background, in order to differentiate foreground objects.
