A method for analyz ing the structu re of the white backgr ound in docu ment images is describ ed, along with applic ations to the proble m of isolati ng blocks of machine -printe d text. The appro ach is based on computa tionalgeometry algorith ms for off-li ne enumera tion of maximal white rectan gles and on-line rectan gle unific ation. These suppo rt a fast, simple, and gener al heuri stic ...

Busy period analysis for M/G/1 and G/M/1 type queues with restricted accessibility

We consider two models of M=G=1 and G=M=1 type queueing systems with restricted accessibility. Let (V (t))t¿0 be the virtual waiting time process, let Sn be the time required for a full service of the nth customer and let n be his arrival time. In both models there is a capacity bound v∗ ∈ (0;∞): In Model I the amount of service given to the nth customer is equal to min[Sn; v∗ − V ( n−)], i.e. ...

Analysis of M/G/ 1 queueing model with state dependent arrival and vacation

This investigation deals with single server queueing system wherein the arrival of the units follow Poisson process with varying arrival rates in different states and the service time of the units is arbitrary (general) distributed. The server may take a vacation of a fixed duration or may continue to be available in the system for next service. Using the probability argument, we construct the ...
