A software tool for the development, prototyping and emulation of cellular processor array hardware is presented. APRON provides a dasiavirtual processor arraypsila that operates at high speed, that can be extended to form vision systems, multi-layer neural networks, cellular neural networks and neuromorphic arrays.
In this paper a new technique for segmenting and tracking moving objects in a user-defined control area is presented. It is based on an active contours technique called pixel-level snakes (PLS) whose capabilities to manage changes of contour topology and to introduce additional constraints in the contour evolution are used to define a control area as well as to segment and track moving objects. Furthermore,...
We present an application of a massively parallel processor array VLSI circuit to the implementation of neural networks in complex architectural arrangements. The work was motivated by existing biologically plausible models of a set of sub-cortical nuclei -the basal ganglia. The model includes 5 layers, each consisting of 16384 leaky integrator neurons, with inter-layer synaptic weights forming various...
Retinal vessel tree extraction from angiography images plays an important role not only in the medical domain, but also in biometric identification applications. From the image processing point of view, many algorithms and strategies have been developed to deal with this topic. Although reliable results have been obtained, the main disadvantage in most of these proposals is still the high computation...
