Concept of ambiguity and applications to security and transportation safety

Some concerns of measurement for biometric analysis and synthesis are investigated. This paper reexamines the nature of definition of “measurement” of distance between two objects or image patterns, which is essential for comparing the “similarity” of patterns. According to [19], biometric refers to the studies of analysis, synthesis, modeling and simulation of human behavior by computers, including mainly recognition of hand printed words, machines printed characters, handwriting, fingerprint, signature, facial expression, speech, voice, emotion and iris etc. The key idea is the “measurement” between different input image. It deals with fundamental phenomena of “measurement”. Preliminary findings show that the concepts of “segmentation” and “disambiguation” are extremely important. Even methods that has 99.999 % accuracy rate, a poorly or ill considered pre-designed road poster or input pattern could easily destroy its effectiveness and lower the overall performance accurate rate to less than 50%. This paper propose a method to disambiguate ambiguous signs.
