Author: Keqin Summary: Turn picture into another picture with basic geometries. Abstract: Abstract geometries always make a very beautiful picture when combining them together. And real world is built with basic points, lines, and shapes. So use the real world as the input and output the abstract geometries picture. Repository:

Idea comes from a generative artist’s work. He uses some basic geometries to build a picture. It’s naturally beautiful. Then I found that if we turn the real world into a 2D picture. It’s comprised of points, lines and some basic geometric shapes. So why not take a real world picture as an input and then generate another picture comprised with basic geometric shapes.

I use openframeworks to make the project. Because OF has more powerful Computer Vision support. To accomplish my project, I need a lot of Computer Vision algorithms to recognize the picture.

Firstly, I use Canny Edge Detection to make the lines and shapes in the picture more obvious for computer to read. Then use Hough Transform to detect the shapes in the pictures. Because the performance of Computer Vision algorithm depends on what the picture is and what the attribute is. So I make a user interface to let user to customize their own generative picture. Some basic attribute can be changed and user can also decide whether to put the circle or contour into the generative picture. I take a easy way to generate color. It’s mix white with a random color and this makes color beautiful.

Here’s an example. Version with circle and contour.

About Keqin

I'm Keqin Dou. I'm now the first year Tangible Interaction Design Master student at Carnegie Mellon University. I learnt more things about interaction design, physical prototyping than computer science. So I believe I can do anything range from development to design. I also held a BS degree in Computer Science and Technology at University of Science and Technology,Beijing. During my undergraduate time, I did the HCI, TUI research in HCI lab of Chinese Academy of Sciences. I'm also very interesting in chanlleging uncomforable zones.
