In the U.S., performance assessment on the Automatic Exposure Control system (AEC) is managed according to the Mammography Quality Standards Act (MQSA). However, The AEC is not available in the performance assessment conducted in Korea. Also, there is no study made on the performance of the automatic exposure control system for mammography in Korea. For this reason, this study examined the perf...

Cross–derivatives are mixed partial derivatives that are obtained by differentiating at most once in every coordinate direction. They are a computational tool in combinatorics and high– dimensional integration. Here we present two methods of computing exact values of all cross– derivatives at a given point both following the general philosophy of automatic differentiation. Implementation detail...

The research summarised here is working towards automatic control systems for cameras, in support of remote meetings. Progress is reported on several fronts: use of active contours to track heads, stereo sound analysis; applying particle filtering to handle both visual and aural clutter; and the use of exemplars for stabilisation of inter-frame matching.

Well-posedness of the considered SC problem: We begin our analysis of the considered SC problem by providing the necessary and sufficient condition for the existence of a correct supervisor. For the systematic characterization of this feasibility condition, we need the following definition: Definition 1. Consider an s-DES G ≡ 〈X × S, Σ ∪ E, δ, (x0, s0)〉, and the supervisor Γ∅ defined by: ∀(x, s...
