TellyVision
Kester Sheridan
Abstract
There is a growing trend in technology for convergence. Modern devices
such as mobile phones do not have just one function but many -
combining the functionality of a telephone, a camera and an mp3 player
all into one device. This trend can also been seen in home
entertainment with the convergence of the computer and television into
one single entertainment centre. For me this convergence of the
television set and the computer provides an interesting opportunity for
the artist to truly ‘interrupt live television’, allowing us to apply
the techniques developed by video artists to the live medium of
television and so interrupt the expectations of the spectator for a
medium that is taken so much for granted. I shall discuss the design
and development of the ‘Telly Vision’ application, which provides the
tools for me as an artist to create such art work which challenges the
spectator’s view of the medium. I will also discuss the design and
development of the ‘Media Montage’ application which allows me to
create collages using images, sounds and movies.

Abstract
Computer vision and image processing in java applied to drawing
generation. The AIKON system in its present development is able to
sketch faces automatically, starting from a picture, typically a
photographic snapshot of a scene with humans. Once a digital image is
considered, the system automatically finds where some of the faces (or
face-like patterns) are and isolate these. Each face image pattern is
then used to produce a stylised portrait. The style which the system
aims at using is derived from the one I have developed over the years
in my artistic practice. The goal is for the final system to mimic the
process developed by myself, rather than aiming at results exactly
reproducing my way of drawing a portrait. Nevertheless, the produced
sketches are in the style of the artist. Various steps in the process
of producing a sketch by the artist were isolated, including: image
segmentation, filtering, shape selection and depiction, filling
and shading. The implementation of these steps relies on an
understanding of human visual perception, of the artist’s work process,
and of advances made in computer vision.
