best way to implement smart blur filter

in General Discussion • Other • 6 months ago

I'm thinking of processing some images to produce an effect similar to photoshop's smart blur or surface blur.

I found this link where someone already wrote the code in java. Aside from straight translating it into processing, I'm just wondering if there are any improvements that can be made? Using bit operation for colour manipulation - not sure if this is applicable in this instance. Really anything to speed this up.

We do this all the time in Processing...

The best way is to just reuse the class as given: Processing offers bridges between PImage and BufferedImage.
Since the class uses some Java image processing facilities, a direct port to pure Processing (using pixels[] and such) is a bit more work.
See http://bazaar.launchpad.net/~philho/+junk/Processing/files/head:/_QuickExperiments/_Java/SmartBlurDemo/ for a simple test.

yeah,

the whole bufferedImage had me stumped all day, was thinking about converting the input pimage to bufferedImage but wasn't sure how to go about it. ConvolveOp seems like a quick way of doing convulsion matrix operations which I didn't know about. Started going through the source code for PImage and noticed it was based on the bufferedimage - I would have been at this for weeks still, you make it seem so easy. Thanks.
