Interactive system for painting artworks by regions using a robot

In this work we present an interactive system capable of producing realistic artworks with acrylic paint based on a cartesian robot. This system focuses on painting artworks by regions, and can be applied for example in the painting of objects such as fruits, flowers, leaves and other individual objects. We have divided the development of the proposed system in three interactive stages: (1) interactive segmentation of work regions, (2) interactive designing of the field for orienting the brush strokes by tracing curves manually in each region and interpolating the curves to generate the vector field, and (3) painting by regions with the field. With our system it is possible to reproduce interactively an image producing pleasant results. The experimental results are presented by painting an apple with three main regions, for this we have utilized a realistic pictorial style and a monochromatic palette of 5 colors.
