The next meter you see someone with a make up elan that puts David Bowie to disgrace , do n’t laugh too much . He or she may be cleverly fooling face recognition and detection system with a crazy or asymmetrical design .
It ’s generally not prosperous to deflect being spotted by face recognition and detection systems because they use a rather solid algorithm to key out face :
Based on the so - called Viola - Jones method , the algorithm examines the spatial relationship of an object captured in an image and looks for features usually found in typeface . Most typeface have a dark realm just above the eyes , while the buttock bones and nozzle nosepiece will seem sluttish . When the algorithm detects enough such property , it opine the objective is a face . The method is generally see as in effect . erroneousness are in favor of false positive , stool it hard for unobstructed look to escape notice when they are n’t captured at an slant .
While the algorithm is effective , it can be fooled with make up employ to “ alter the contrasts the technology reckon for . ” Adam Harvey , a student at New York University , has let out that “ dour patterns put on around eyes and impudence osseous tissue ” do this trick quite well by “ throwing of the symmetry ” and progress to you look silly .
While Harvey ’s approach is n’t foolproof , it shows that face realisation and detection systems are n’t perfect either . That and the fact that Mr. Bowie might ’ve been on to something . [ The Register ]
