Title: [IMAGE PROCESSING] Median Filter
Post by: Rbz on July 30, 2011
Here's my entry.

As the compo rules says "You only need to look through the list of photoshop filters for inspiration!" and so I did, I found median filter interesting and searched for more information on how it's done. You can find more info here (http://en.wikipedia.org/wiki/Median_filter) and here. (http://homepages.inf.ed.ac.uk/rbf/HIPR2/median.htm)
During my tests, a bug turned into feature once more, instead of using a color buffer I used a grayscale buffer combined with color buffer to produce some sort of "painted image effect" which looked interesting to me so it was added here as an option.

The program will ask (console window) for how much passes the filter will run, which could be from 1 to 20, of course with more passes, more time it will take to render. Type "y" or "n" if you want to see the painter mode or normal median filter mode.

The program will only load BITMAP images, to load a new image just drag and drop a .bmp file on the executable file or type: "Median_Filter your_image.bmp"

Wow, what a nice effect. Looks a lot like a painting you might see on black velvet.
I think the bird was a nice choice to showcase it.

It gives a really cool cotton wool effect to the image :)

Great stuff RBZ.

The brush stroke effect really brings out the feathery appearance of the parrot - and parrots are the coolest herbivorous birds around :clap:

It's nice movie indeed, some karma for your niece too :)

About the parrot (also called "papagaio" here), I found it on pouet (http://www.pouet.net/topic.php?which=7464&page=149), it was instant love :)
