Prof. Dr. Puteh Saad Neural networks (Computer science) Cognition in animals Object recognition Moment invariant Master of Science (Computer Engineering) Object recognition and classification is an essential routine in our daily lives. Our eyes act as a camera capturing the image of particular object and sending it to the brain to be recognized. Thus, the eye vision system inspires researchers to create machine vision systems. As a significant part of the machine vision system, this research focused on two (2) important phases of the system; feature extraction and classification. As for the feature extraction six (6) different types of moment invariant techniques namely Geometric moment invariant (GMI), United moment invariant (UMI), Zernike moment invariant (ZMI), Legendre moment invariant (LMI), Tchebichefmoment invariant (I'MI) and Krawtchouk moment invariant (KMI) are used to extract the global shape features of the binary insect images. These features are then channeled to the Fuzzy ARTMAP (FAM) and Gaussian ARTMAP( GAM )neural network to be classified and recognized. In the GAM neural network, a gamma threshold is proposed to find the optimal value for gamma parameter acting as the initial value for a Gaussian distribution in the training phase. It is found that KMI is the best technique for features extraction of the global shape information of the insect images as compared to GMI, UM!, ZM!, LMI and TMI. The finding is based on the lowest value of Total Min Absolute Error (I'PMAE) (0.03%-1.01). The training and testing method for both neural networks is based on 4- folds cross validation technique. It is also found that the performance of F AM neural network is influenced by the types of normalization technique utilized. The Improved Linear Scaling (ILS) normalization technique generated the highest classification rate by the F AM neural network when compared to Unit Range (UR) and Improved Unit Range (IUR). It is further found that GAM neural network is a better insect classification technique when compared to F AM neural network producing the classification accuracy up to 99.58% whereby the classification accuracy of FAM neural network is 82%. 2019-11-29T03:39:23Z 2019-11-29T03:39:23Z 2006 Thesis http://dspace.unimap.edu.my:80/xmlui/handle/123456789/63439 en Universiti Malaysia Perlis (UniMAP) School of Computer and Communication Engineering
