Paper accepted for eCAADe conference

My paper Frequency analysis of wood textures has been accepted for the eCAADe conference. I will present it on Thursday, September 20 in Delft, NL. Video of Session…

Interactive Color Clusters

This applet shows the processing.js implementation of the kmeans-colordisc tool presented previously. run | next | less | morerun : start distribution of cluster centers and draw disc diagram…

Configurator for Fritz Haller’s System midi

I made up a series of videos showing the implementation of a configurator for the midi system by Fritz Haller. It is written in VectorScript, the built in…

Sorting Image Features

The studies on Fourier Analysis of images is being continued. For the following studies in this field – and other tasks relying on matrix math – I switched…

kmeans

Picture Statistics

Working with images and their statistical representation, I came across a site (link broken)¬†describing the use of k-means clustering and histograms to visualise main colors and their distribution…

WoodSOM

Wood SOM

With the same set of wood image data, a SOM (self-organizing map, Kohonen) was trained. An introductory description and the code for this example was originally taken from…

Color Spaces

When thinking about how to encode color values of images in double matrices, I stumbled upon some interesting facts beyond just RGB (additive, screen) and CMYK (subtractive, printer)…

The Sound of Wood

The same set of sample images serving as input for the FFT analysis. The frequency filter is set to a radius of four. The main textural features of…

The Sound of Images

To be able to compare to images by their texure, they must be quantified in a way other than just plotting the pixels in RGB space.A useful method…

Mapping Wood

What if materials or surface textures used in architecture were only renderings of the material’s data-space? This ongoing project understands texture samples as pure data vectors and aims…

Wood Samples

Wood as a pointcloud

The first sketch just displays 3 dimensional scatter plots, histogramms and some sort of what in statistics is called standard deviation. On the gound plan, the sample images…

Experiments with SOM

Self-organizing maps (SOM) are useful for displaying and clustering high dimensional vectors on a two (or three) dimensional map. Below are a series of experiments I made using…
