ErosionDilationWithSliders.py
A simple Python OpenCV program demonstrating Erosion and Dilation
It provides 4 slidebars, each modifying the operation performed on 1 of 4 source images. Changing the source image really helps illustrate the two Erosion and Dilation operations.
Slidebar 1 ("Type") has 2 positions, position 0 makes the image operation erosion and position 1 makes the image operation dilation.
Slidebar 2 ("Src") has 4 positions, each corresponding to a different source image to be eroded or dilated, according to slider 1's position.
Slidebar 3 ("Kernel") has 3 positions, corresponding to a 3x3, a 5x5 or a 7x7 oval kernel
Slidebar 4 ("Iterations") has 11 positions corresponding to the number of iterations the erode or dilate will perform, 0 means do nothing
This requires OpenCV with Python to be installed on the system. Just cd into the ScriptFiles directory and execute:
python ErosionDilationWithSliders.py
