Edge Detection Comparison App

Interactively compare edge detection methods side by side using App Designer.

About This Example

This example shows how to build an app to interactively detect edges in images using App Designer. Using the Edge Detection Comparison App, users can detect edges in the same image using two different edge detection methods and compare the results side by side. The app compares the results of edge detection methods supported by the edge function. The example also demonstrates how to build a reusable custom UI component that inherits from ComponentContainer to improve code reusability and maintainability.
