Implementation of principal component analysis method for detection of chlorine and bleach in rice

摘要

Distribution of bleach and chlorine rice makes some people uneasy because it is dangerous to health. The author conducted a simulation for implemantation the method of Principal Component Analysis to detect bleach and chlorine on rice with Matlab R2013a. This study focuses on the shape, texture, color, and position Pandanwangi, Rojolele, and Setra Ramos Rice intact. The result is an Euclidean value that determines the accuracy value. Accuracy of 60 samples was 51.76%. As for each type of rice has a different value of accuracy. Accuracy of Rice Pandanwangi 85% (accurate), Rojolele Rice 45% (not accurate) and Setra Ramos Rice 20% (not accurate).
