— This paper addresses the problem of registering the hexapedal robot, RHex, relative to a known set of beacons, by real-time visual servoing. A suitably constructed navigation f...
We classify the minimal blocking sets of size 15 in PG(2, 9). We show that the only examples are the projective triangle and the sporadic example arising from the secants to the u...
In this paper we develop a systematic theory about local structure of moving images in terms of Galilean differential invariants. We argue that Galilean invariants are useful for s...
Amplitude for color mixing is different from other amplitudes such as loudness. Color amplitude must refer to a light's ability to look different from other lights, to expres...
Modern database applications including computeraided design (CAD), medical imaging, or molecular biology impose new requirements on spatial query processing. Particular problems a...
