Colour Model Y′COCG
An in-depth discussion of the colour model Y′COCG. The advantage this colour model has over the widely used Y′CBCR is simpler – that means faster – computation, a stronger de-correlation of the colour planes, and dramatically reduced rounding errors. The very popular video codec H.264 is based on it, as well as the BBC’s own Dirac.
This is an advanced course: the attendees should be familiar with high-school maths, including functions, linear transformations and elementary 3 x 3 matrix operations.
- A refresher on colour models and chroma subsampling;
- Ladies and Gentlemen, His Majesty Y′COCG by Bill Shakespeare;
- an ounce of codec programming;
- in-depth H.264 – and Dirac at a glance.
- On Thursday 2nd of April 2015, from 14:00 to 17:00, at the Swiss Federal Institute of Technology in Écublens (a suburb of Lausanne, Switzerland).
- The admission fee is CHF 50 for renting the equipped classroom, and an inscription is required, as the places are limited to 20 computer programmers, digital archivists and outlandish scholars.
- All information gathered at this encounter could be used, without further notice, for our training courses, including A Course in Codec Programming.
- In the morning an optional visit of our facility is organised.
- And in the evening an optional dinner is organised in John Kerry’s favourite crêperie.
