Spectroscopic Detection of Caries Lesions

Pseudocode 1

Pseudocode for classifying a sample. Samples in the positive class are carious, and samples in the negative class are healthy. A sample ^→𝑥 is a vector, where each component 𝑥_𝑖  equals the normalized intensity at a given wavelength 𝜆_𝑖.

CLASSIFY(𝑅, ^→𝑥)

(1) // Classify sample ^→𝑥 using the set of rules 𝑅

(2)  for  𝑖=1  to  𝑅.length

(3)  𝑡=𝑅[𝑖].limitThreshold // Threshold intensity 𝐼^⋆

(4)  𝑗=𝑅[𝑖].limitIndex // Index of wavelength 𝜆_𝑖

(5) if  𝑅[𝑖].limitType ==  UPPER  and  𝑥_𝑗>𝑡

(6)   return (+1)

(7) elseif  𝑅[𝑖].limitType ==  LOWER  and  𝑥_𝑗<𝑡

(8)   return  (+1)

(9)  return (−1) // No rule indicated sample as positive
