SOFT­WARE TO PRE­VENT DEATHS

Gadgets and Gizmos (India) - - BIT RATE -

A new piece of soft­ware has been de­vel­oped to de­tect when

crowds are start­ing to build up to dan­ger­ous lev­els. By pre-

empt­ing ri­ots it will then give se­cu­rity per­son­nel the chance

to dis­perse crowds to safety. Bar­bara Krausz, from the

Fraun­hofer In­sti­tute for In­tel­li­gent Anal­y­sis and In­for­ma­tion

Sys­tems in Sankt Au­gustin, Ger­many, de­vel­oped the sys­tem.

She found that when peo­ple be­come trapped in a highly

con­gested area, they sway slowly from side to side in an

ef­fort to keep their bal­ance. The soft­ware no­tices this col­lec-

tive mo­tion by scru­ti­n­is­ing the move­ment of each pixel

be­tween dif­fer­ent frames of crowd video footage.
