Abstract

This paper presents the modeling of face recognition using feature extraction based on Principal Component Analysis (PCA) and Support Vector Machine (SVM) as a classifier. Three PCA techniques were compared, they are 1DPCA, 2DPCA and Bi-2DPCA. Meanwhile, three type of SVM kernel functions-linear, polynomial, and radial basis function (RBF) were used. The experiment used the ORL Face Database AT&T Laboratory, which contain 400 images with 10 images per each person. The leave one out method is used for validating each pair of extraction and classifier method. The highest accuracy is obtained by a combination of linear kernel and Bi-2DPCA85%, with 94.25%, and also the fastest computation time, is 15.34 seconds.

Abstract

One of Indonesian election isthe local elections for regional head thatare still using conventional election type.The conventional election type stillspend a lot of time and prone of mistakesmade by humans, including fraudscommitted by certain parties. Thisresearch is based on two centralfacilities protocol in Schneier book(1996) and a continuation of previousresearch by Sireesha and Chakchai(2005) which has developed a secureelection with two central facilitiesprotocol that implement the developmentof Central Legitimization Agency (CLA)and the Central Tabulating Facilities(CTF) to create a secure virtualelections and Wardhani (2009) whichimplement the protocol Two centralfacilities at IPB online voting. Thisresearch collaboration with the KPUBogor and Bogor Information andCommunications, for the purposes ofanalyzing and studying the variouselections policy of regional heads ofBogor. Through this study found adesign system using a protocol e-votingTwo central facilities modified.However, this design is still requirefurther research to be applicable forBogor Regional Head election.
