Image Filters: Colourful Processors


Today has been my best day in terms of Likes and Views on my website. I have come to the obvious conclusion that most people are more interested in seeing pretty pictures than they are in reading articles on source code.

That’s ok, I also like pretty pictures SmileI have uploaded some more eye candy. The images were created by modifying an image originally authored by Konstantin Lanzet. The original image file is licensed under the Attribution-Share Alike 3.0 Unported license, and can be downloaded from .

As a point of interest, all of the filters implemented were done through software I had written from scratch. Most of the application source code have been discussed in various articles and published here on my . All applications and related source code are of course open source.

This is what the original image looks like:


After applying various colour filters and a bit of copy and paste the result:








Image Filters: Light bulb Patterns


I’ve started development on pattern based colour filtering today. The software still needs some work, but so far the results are starting to look quite promising.

At this point I’ve only implemented variable sized checkerboard patterns. The idea being to divide an image into a number of squares and then to only include alternating squares when applying various colour filters.

Keep in mind all of the images shown below were generated from the same source image. The original image reflects a fairly standard image of a clear glass bayonet light bulb.
