Abstract
A compact representation for digital images is described which is based on a traversal of the quad tree form. It is designed to store coloured pictures of the type which are displayed on a raster scan device using a colour lookup table. Two experiments are reported which show that the code appears to occupy 65% of the space of a previous traversal scheme, and 105% of that of a run length encoding technique.Keywords
