The original images below were convolved with masks
The source code of the program which generated the following
images is located here.
Output of convolution program
Image 1 convolved with Mask 1

Image 1 convolved with Mask 3
Image 2 convolved with Mask 1
Image 2 convolved with Mask 2
Image 2 convolved with Mask 3
Answers to short questions

- These masks are vertical edge detection masks; they blur the image
but keep the vertical edges distinct.
- Small masks are good because the edges are more distinct. Larger
masks blur the image, but can detect subtler edge changes.
- A large horizontal edge detection mask would be good for this
scenario (detecting the horizon at sea). Something like
This allows for detecting a subtle horizontal edge in the photo,
suitable for finding the horizon.
