PhilipLB Posted March 6, 2008 Share Posted March 6, 2008 Hi, first try with some ui. A simple Mexican Hat Edge Detect filter. Mexican Hat Edge Detect.zip Quote Link to comment Share on other sites More sharing options...
Bobofthedead Posted March 6, 2008 Share Posted March 6, 2008 Don't we have an edge detect already? Actually, stuff the rhetoric, we do. It's a default effect that comes with PdN. You can find it in the Stylize menu. Keep trying though - don't let me stop you! Quote "I am the anarchist, I am the antichrist, I am the walrus, G'JOO G'GOO G'JOOB!"

PhilipLB Posted March 6, 2008 Author Share Posted March 6, 2008 Sure, but a different one with some angle-stuff. Quote Link to comment Share on other sites More sharing options...
Bobofthedead Posted March 6, 2008 Share Posted March 6, 2008 What's this then? If there's much of a difference, could you upload a picture and explain the differences between yours and the default please?

PhilipLB Posted March 6, 2008 Author Share Posted March 6, 2008 I don't know, how the default-one works. I think it goes in a specific angle with scanlines over the image and the result is the first derive of the pixels in this direction. Mine goes in x- and y-direction with the second derive and combines the two results (Laplace-filter). First, it reduces the noise with a gaussian blurr. -> Laplace-Kernel: 0 1 0 1 -4 1 0 1 0 Quote Link to comment Share on other sites More sharing options...
Bobofthedead Posted March 6, 2008 Share Posted March 6, 2008 Do these changes have a significant effect on the outcome? Is the UI changed much? Can you upload "comparison" pictures of both yours and the default one? Quote "I am the anarchist, I am the antichrist, I am the walrus, G'JOO G'GOO G'JOOB!"

PhilipLB Posted March 6, 2008 Author Share Posted March 6, 2008 The difference: The default one only detects angles in a certain direction. Mine detects all edges. See on the image, how some edges aren't detected by the default-one. The ui of mine is simple. Just a slider to controll the amount of noise-reduce. First image: Really nice result with noise-reduce = 1 and then normalized (See viewtopic.php?f=16&t=23154 ). Quote Link to comment Share on other sites More sharing options...
Myrddin Posted March 6, 2008 Share Posted March 6, 2008 You have to admit, no matter how similar the two are, PhilipLB's results much crisper lines. In my opinion. Quote How to Save Your Images under Different File Types My dA Gallery Link to comment Share on other sites More sharing options...
Bobofthedead Posted March 10, 2008 Share Posted March 10, 2008 Yes, that does look much better than the default one. Thanks for clearing that one up!

Shadow Posted April 7, 2008 Share Posted April 7, 2008 You have to admit, no matter how similar the two are, PhilipLB's results much crisper lines. In my opinion. Agreed, can we get this one to replace the default one? Quote Link to comment Share on other sites More sharing options...
