What is Picture to People ?

"Picture to People" (P2P) is a huge Computer Graphics project. It was started to create new softwares able to make 2D drawing, 3D rendering, vexel drawing, text effects, photo effects, image filtering and other complex Computer Graphics operations. It has been made from scratch, including its low level Computer Graphics libraries like Maccala. Nowadays, most final features produced for this project are released as free online tools available from its official website. This blog talks about Computer Graphics, mainly concerning Picture to People development.

Vectorization 3

I have dealt with my vectorization library these days to make it suitable to my needs in http://www.picturetopeople.org. I want everything very direct and easy there.

I have made some key modifications, so now instead of need to adjust some no intuitive parameters, you can get kind of different results by applying the vectorization several times in a row. Of course, the output of one iteration is the input of the next one.

The first image is the original image vectorized. It's a very hard image to vectorize, since its global entropy doesn't tell much about it and it's local entropy is unstable. The next images show the successive use of the vectorization library, always having the previous image as input.

In a case like this, if some details are false positives, usually you can remove it by reapplying the vectorization.

You will need to click the images the see them in full size.
