The template matching demonstration convolves an image with a 3*3 kernel. With an appropriate definition of the kernel , the algorithm can be used as a edge detector.

There are predefined kernels to standard detectors, but you can also enter your own kernel (Customize).

This demonstrations exists in 2 forms:

• Running on our server (ION/Java)
• Running on the client (Pure Java)

1. Choose an image to process. The Octagon is a good test image to use the predefined detectors
2. Choose a predefined detectors or customize your own one by enter the 3*3 kernel.
3. Press on the "Run" button to compute the result image.

For the ION/Java demo, by pressing on the "Capture" button you have an opportunity to save the image in GIF format.
