DEVELOPMENT OF AN INTELLIGENT RECOGNITION AND SORTING SYSTEM

ENGLISH ABSTRACT: This paper presents the design of an intelligent recognition and sorting system. Intelligence is included in the system by using a multilayer feed-forward artificial neural network (ANN) for image recognition. Full duplex Bluetooth communication is used between the intelligent system and a robot-control computer. Image compression and principal component analysis (PCA) reduce the dimensionality of the data, and only the salient feature vectors of an image are used for image recognition. A control signal guides a robot arm to place an object into an allocated space. The system is relatively immune to noise, and can generalise when faced with missing data. AFRIKAANSE OPSOMMING: Hierdie artikel hou die ontwerp van ’n intelligente herkenning- en sorteringsisteem voor. Intelligensie word ingebou in die sisteem deur middel van ’n kunsmatige neurale netwerk vir beeldherkenning. Kommunikasie word bewerkstellig tussen die intelligente sisteem en ’n robot-beheerde rekenaar. Beeldkompressie en hoofkomponentanalise verminder die dimensionaliteit van die data en slegs kritiese kenvektore word aangewend vir beeldherkenning. ’n Beheersein rig die robotarm om die objek op ’n aangewese plek te plaas. Die sisteem is relatief immuun teen geraas en kan veralgemeen wanneer dit gekonfronteer word deur ontbrekende data.
