New homepage layout

This is my first post with the new homepage layout.

The design goal was simplicity and elegance. I wanted style patterns of Richard Meier and Max Bill.

I used white as main color, as white includes all rainbow colors. Grey was added to bring in slight contrast. Accent colors are red for energy, blue for thought, orange for communication and green for imagination.

Lines are clear, contents addressable. To lead your eyes without constraining them.

The fonts used are Arial Rounded MT Bold for headings, Calibri for running text. I did not choose Futura, because it looks harsh and angular. I needed a contrast to the clear drawn layout. I want to convey an organic, personal emotion.

The content is written in Textile and plain HTML while Jekyll generates static html files. The CSS layout was written by myself, based on YUI 3 to reset browser CSS layout and typography. Comments are added dynamically via Disqus. The content itself is versioned with Git.

JPEG 2000 Explained

JPEG 2000 is the official successor to JPEG. The still picture standard developed by the Joint Photographic Expert Group inherits newest compression developments. The file format offers several improvements to enable its use in even more applications.

The JPEG 2000 still image format offers several improvements. The image quality is superior at the same compression rate. The discrete wavelet transformation is the main technological reason for the high performance of the standard. The JPEG 2000 container also offers good error resilience, selective decompression, lossless compression.

This explained in detail in my JPEG 2000 seminar paper at the Ulm University. The presentation slides are also provided.

I also recommend to take a look at quality comparison by example and a publication by A. Skodras et al.: “The JPEG 2000 Still Image Compression Standard”.
