1/2 & 1/3 Pixel Nudge Custom Convolution
Anyway - the links still work (for now) and you can download the custom convolution kernels here:
With the recent EXCELLENT posts from Chris Russ on custom convolution (see link below) and his great free custom 'custom' convolution filter I will shortly experiment with these kernels with more understanding than in the past (thanks Chris), I just wanted to share the links first!
Looks like I'm turning into a convolution geek - when I am a diehard GUI person. <g>
Quick Test Results of Sub Pixel Motion Convolution:
Rasterized EPS font, 3pt black Times text and also inverted (very small fine serifs) -
Did a offset filter of 1 pix and a 50% opacity fade and compared it to the custom filter convolution kernel for 1/2 pixel...
The custom convolution method is the winner - sharper serifs and fine detail (which the fade command with the offset filter blurs slightly more), although printing may not show the difference...it is probably a big deal though when stitching or aligning images, which is probably where Chris is coming from with his third party nudge filter in the Optipix plug-in package.
