This volume presents the proceedings of the 2nd International Workshop on Algebraic
Frames for the Perception and Action Cycle. AFPAC 2000. held in Kiel,
Germany, 10–11 September 2000. The presented topics cover new results in the
conceptualization, design, and implementation of visual sensor-based robotics
and autonomous systems. Special emphasis is placed on the role of algebraic
modelling in the relevant disciplines, such as robotics, computer vision, theory
of multidimensional signals, and neural computation. The aims of the workshop
are twofold: first, discussion of the impact of algebraic embedding of the task
at hand on the emergence of new qualities of modelling and second, facing the
strong relations between dominant geometric problems and algebraic modelling
