JIGSAW is a family of algorithms for recovering the unknown spatial
mapping of very large sets of sensors. This enables it to localise a
set of sensors within a space such as a farm or a battleground, to
integrate, or 'mosaic' a set of video cameras, and to perform
large-scale analysis on databases.
JIGSAW is capable of handling hundreds of thousands of simultaneous
inputs, whether they be sensor signals, pixel values, or columns of
data. It operates in real-time.
JIGSAW can also be applied
to the integration of control systems to sensory systems (see C-SAW).
Problems Jigsaw Solves
JIGSAW is a platform technology.
It can be applied to solving many different problems where there is a
need to:
Extract
spatial information from a set of sensor signals
Infer
the relative positions of a set of sensors by considering only the
behaviour of the delivered signals.
These basic functions allow JIGSAW to solve a
variety of problems relating to spatial mapping.
Spatial mapping allows us to see the large-scale
patterns across multiple data points. Spatial mapping underlies
navigation, identification of the extension of, and boundaries between,
objects and regions. As children, we develop competence to operate in
space quite unconsciously, and without external instruction.
Consequently, spatial awareness is often taken for granted, and just
assumed to be present in intelligent systems. Only once spatial
awareness is absent or dysfunctional, are we faced with the problem of
how to create and maintain it.
The problem addressed by JIGSAW is how to derive
spatial mappings with no prior concepts of distance, direction,
locality, and their derivatives such as up, down, further, between,
around, etc.
