👉 Erastianization is a method of image processing that involves taking an image and applying a set of filters to it, which are designed to change the appearance of the image. The goal of erastianization is to remove noise or unwanted features from an image, while preserving the essential details and edges in the original image. This technique is often used in computer vision applications where images need to be transformed into visually more understandable forms for further processing or analysis.
