Abstract

In this paper, we extend our earlier work in image algebra (IA)-based optical processing to the optical computation of high-level image operations (HLIOs) such as connected component labelling, determining component adjacency graphs, finding corresponding points in stereo pair images, and computing the Euler number. In particular, we transform an IA expression that describes a given image procedure into the dataflow graph of the corresponding MEA-conformable (Multiple Execution Array) architecture. From the MEA dataflow graph, we deduce the components and connectivity of a corresponding optical processor. Analyses emphasize computational cost inclusive of propagation time, as well as information loss expected from optical devices such as Spatial Light Modulators.
