The 2 quantity set LNCS 4843 and LNCS 4844 constitutes the refereed lawsuits of the eighth Asian convention on computing device imaginative and prescient, ACCV 2007, held in Tokyo, Japan, in November 2007. The forty six revised complete papers, three planary and invited talks, and one hundred thirty revised poster papers of the 2 volumes have been rigorously reviewed and seleceted from 551 submissions.

(a) Continuous-time system; (b) sampled-data system. that the steady-state response to sinusoidal excitations is sinusoidal with the frequency of the excitation signal. It will be shown that computer-controlled systems behave in a much marc complicated way because sampling will create signals with new frequencies. This can drastically deteriorate performance if proper precautions are not taken.

The inverse problem offinding the continuous-time system that corresponds to a given discrete-time system is also treated in Sec. 3. The general solution of forced difference equations is given in Sec. 4. 6 deal with transformation of state-space models and the connection between state-space and input-output models. Shift operators are used to describe input-output mod- in 30 Sec. 2 Sampling Continuous-Time Signals 31 els, Shift-operator calculus is equivalent to the use of differential operators for continuous-time systems.
