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,...
In this paper we present an implementation of an asynchronous cellular processor array that facilitates binary trigger-wave propagations, extensively used in various image processing algorithms. The circuit operates in a continuous-time mode, achieving high operational performance and low power consumption. A 24 times 60 proof-of-concept array integrated circuit has been fabricated in a 0.35 mum 3-metal...
