Edge Detection
What is edge detection and how is it utilized in motion graphics?
GLOSSARY
In motion graphics, Edge Detection is a technique used to identify the points in an image where sharp color transitions occur, indicating the boundaries of objects. This process is crucial for creating effects that emphasize structure, for enhancing visuals with outline effects, or for keying and compositing tasks where precise object borders are needed.
Edge detection can be visualized with a character set against a detailed backdrop. This technique would highlight the character’s outline, sharpening their profile and distinguishing them from the scene, allowing for a crisp, focused subject even amidst a complex environment.
Technical definition
This involves using algorithms that scan the image for areas where there are significant color changes along the pixels. The result highlights the edges of objects, which can be further processed or visualized depending on the desired outcome.
