ABSTRACT:
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not applicable.
FIELD OF THE INVENTION
The present invention relates to an image processing method and apparatus and, in particular, discloses a brush stroke palette feedback method.
The present invention further relates to the field of digital image processing and the production of visual artistic effects in computer images.
BACKGROUND OF THE INVENTION
Recently, it has become quite popular with computer images to process the images to produce special effects. These effects often attempt to approximate artistic styles such as impressionist's styles etc. and to produce interesting artistic effects on standard images.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved form of processing an image to produce artistic effects such as those that would be produced by an artist utilising a paint brush.
In accordance with a first aspect of the invention there is provided a method of creating an output image rendering of an arbitrary input color image on a computer system, said output image being made up of output brush strokes, said method comprising the steps of:
defining an initial restricted palette of paint colors;
defining a constrained set of brush strokes;
defining a canvas onto which to render the output image; and
creating said output brush strokes of said output image on said canvas utilizing said constrained set of brush strokes colored from said palette.
