The success of palmprint identification requires the best matching of the test sample from input data and the templates in the palmprint database. The used of holistic and local features separately will have limitations in geometry and variations. Information fusion of palmprint biometric is developed in order to produce a better recognition performance. Thus, this research work presented the fusion of holistic and local features for palmprint recognition. The overall structure of the study takes the form of three major steps includes pre-processing techniques, feature extraction and matching process before proceeds with fusion to combine the holistic and local features. Pre-processing technique is the initial stage to make sure the palmprint image from dataset is cropped and resized into the specific size. The entire proposed method is validated using benchmark PolyU dataset for palmprint recognition analysis. Gabor filter pattern is used to extract important information in holistic features while Discrete Cosine Transform (DCT) is used to extract low frequency energy of local features. Then, the computation of Principal Component Analysis (PCA) is applied to reduce the high dimensional feature space to low dimensional feature space. Low dimensional feature space preserved low frequency information. Classification is the process used to distinguish and classify a new observation based on the training set of data. The purpose of Euclidean distance classifier is to measure the matching value and its closeness between the training and testing feature vectors. Among various fusion levels, matching score level fusion is the most suitable approach in combining the match score from two different matchers because this fusion rule can increase matching accuracy. It is developed by forming a single value for decision process from the matching output of different matching module. In the matching score fusion scheme, weighted sum rule produced superior performance. The best recognition rate of 97% is achieved using 100 subjects. Based on the recognition analysis, there are three important parameters that affect the performance which is the size of input image, the effect of principal components number, and the number of DCT coefficient. 2018 2022-11-08T03:06:39Z 2022-11-08T03:06:39Z Thesis http://dspace.unimap.edu.my:80/xmlui/handle/123456789/76738 en Universiti Malaysia Perlis (UniMAP) Universiti Malaysia Perlis (UniMAP) School of Computer and Communication Engineering
