An example of a realtime Sobel Edge Detection routine.
Also, a little pixellation effect to make it a little more interesting.
Sorry for the small screen but it's pretty intensive and requires two 3*3 masks to be applied to each pixel and calculations on the results.
Anyway, a Youtube video is coming for those who have difficulty running this.
There are a lot of selectable options you can use to see how different effects look with this filter, all totally interactive
Hope you enjoy it!
Btw: The binary is packed with UPX - if your AV software gives an alert, it's your AV software and not the intro!
I'll edit in the vid as soon as it's uploaded to Zootube..
Edit: [Video added]
Please note that the video is captured at 30fps - it looks better if you run the binaries..
