Is there any bilateral filter library existing?

[9tontruck]

Hi,

I am looking for an edge-preserving convolution method written in AS3 but it's really hard to find one.

Bilaterial filter is one of the most popular edge-preserving convolution.

Have any of you seen a bilaterial filter library written in AS3?

If not, can you tell me a good opensource image-processing library such as OpenCV in flash, if there is any?

Thanks,

I know this isn't entirely an answer on your question but a while back I did some decent speed edge detection using this library (AS3 (slow) version and a PixelBender (fast) version available, but old): http://blog.inspirit.ru/?p=297

I'm sure there's quite a bit more out there but it detected edges very well when I used it. With that you can simply make a mask. Then all you need to do duplicate the image, blur the bottom image and use your generated gradient mask to multiply the original image over the blurred image to show the original sharper edges.

If you find a library, please share it!

Thank you sinious. Your solution brought me to http://www.adobe.com/cfusion/exchange/index.cfm?event=extensionDetail&loc=en_us&extid=1789025# which is exactly what I am looking for.

Thanks a lot!
