This research proposes a multimodal multifeature biometric system for human recognition using two traits that is palmprint andirisThe purpose of this research is to analyse integration ofmultimodal andmultifeature biometric systemusing feature level fusionto achieve better performance The main aim of the proposed system is to increase the recognition accuracy using feature levelfusion The features at the feature level fusion are raw biometric data which contains rich information when compared to decisionand matching score level fusion Hence information fused at the feature level is expected to obtain improved recognition accuracyHowever information fused at feature level has the problem of curse in dimensionality here PCA (principal component analysis)is used to diminish the dimensionality of the feature sets as they are high dimensional The proposed multimodal results werecompared with other multimodal and monomodal approaches Out of these comparisons the multimodal multifeature palmprintiris fusion offers significant improvements in the accuracy of the suggested multimodal biometric systemThe proposed algorithmis tested using created virtual multimodal database using UPOL iris database and PolyU palmprint database
1 Introduction
Amultimodal biometric system fuses the evidences presentedby multiple biometric traits Multimodal biometric tech-niques have received the best recognition because additionalinformation between different biometrics could get improvedaccuracy To obtain a successful multibiometric system onehas to essentially implement a good fusingmethodology suchas match score feature and decision level fusion
In order to reduce the error rate and to improve the per-formance accuracy many researchers worked onmultimodalbiometric system Hariprasath and Prabakar [1] proposeda multimodal biometric system using iris and palmprintbased on score level fusion and authentication is obtainedby hamming distance method Gargouri Ben Ayed et al [2]fused fingerprint and faces using match score level fusionusingweighted summethodHereGaborwavelet network forface and LBP fingerprint features are fused Abdolahi et al [3]proposed fuzzy basedmultimodal biometric system by fusing
iris and fingerprint using decision level fusion to provideimproved recognition rate Bahgat et al [4] fused palm veinand face biometric to obtain the better recognition rate
Various multimodal score level fusion schemes wereproposed by different researchers Baig et al [5] proposedscore level fusion of iris and fingerprint which is classifiedusing hamming distance calculationWang et al [6] proposeda score level based multimodal biometric combining iris andpalmprint using Gaussian mixture model Vatsa et al [7]combined multi-instant and multiunit iris verification Wangand Han [8] fused iris and face using score level fusion inwhich different scores are obtained for different traits and theobtained scores are combined using Support VectorMachineWang and Han [9] Kayaoglu et al [10] Zhang et al [11]and Peng et al [12] investigated multimodal biometric fusionusing decision and score level fusion

Shekhar [14] investigated multiple palmprint recognitionusing rank level fusion which uses borda count bucklinhighest rank and logistic regressionMatch score level fusionusing feed forward neural network for the fusion of face andpalmprint has been investigated by Thepade and Bhondave[15] Yang et al [16] investigated multiple dependency ofpalmprint using feature level fusion and score level fusionWang and Han [9] investigated face iris fusion using scorelevel fusion Jain et al [17] investigated the multimodalbiometric system based on the face and hand geometrybiometrics at the score level
Conti et al [18] proposed a multimodal biometric basedon two-fingerprint acquisition which uses score level fusionand obtained an improvement of 6 when compared tomonomodal biometric based system Yang et al [19] usedmatched score level fusion to fuse hand geometry fingerprintand palmprint multimodal biometric system He used aself-constructed database of 97 subjects Besbes et al [20]proposed a hybrid multitrait biometric method using irisand fingerprint Yang et al [16] proposed decision levelfusion fingerprint templates Here assessment was taken byindividual unimodal assessment through an ldquoANDrdquo operator
Most significant contribution published in recent yearspertaining to multimodal biometric fusion focused exten-sively on fusing data at the matching score level and decisionlevel It has been observed thatmost of the important featuresare lost on performing data fusion at the latter stages (matchscore level and decision level) In spite of the abundanceof investigations related to multimodal biometrics relativelylittle work was done at feature level fusion since featurefusion has rich information content compared to fusionat the later stages Therefore the current exploration on amultimodal biometric fusion at the feature level is anticipatedto attain improved recognition accuracy compared to thefusion at the later stages

22 Hierarchical Multiresolution Local Binary Pattern Ojalaet al [22] introduced local binary pattern in 1996 The localbinary pattern is a gray scale invariant texture measureand is a helpful tool to model texture images It tags thepixels representation by using threshold of the pixels ofthe local neighbor around each pixel and considers theresult as binary numbers It is a combining approach todivergent statistical and structural forms of texture anal-ysis The major property of hierarchical multiresolutionLBP is its robustness to monotonic gray scale alterationscaused An added advantage of hierarchical multiresolutionLBP is its computational simplicity to analyze images in

To enhance the performance of LBP operator mul-tiresolution LBP features are used Multiresolution LBPfeatures consist of richer information than the single LBPoperator Conventionally LBP features with different scalesare obtained and concatenated into a lengthy feature Theobtained feature contains enormous information but it has adrawback of curse of dimensionality
Nonuniform pattern contains more useful informationsome of the processing steps are investigated by Raja andGong [23] and Liao et al [24] However the recognition

The proposed methodology for investigating the multimodalmultifeature biometric systems is based on the combinationof palmprint and iris Feature fusion has the advantage ofexploiting rich information from each biometric Figure 5represents proposed feature fusion multimodal biometricsystem based on Gabor and hierarchical multiresolutionLBP extraction The feature vectors are extracted indepen-dently from the preprocessed images of palmprint and irisThese features are normalized to obtain a single vectorThe feature vectors of input images (test image) are thenevaluated with the templates of the database (train image)to produce the output Fusing more than one modalityimproves the recognition accuracy reduces False AcceptanceRate and False Rejection Rate The proposed multimodalmultifeature biometric method overcomes the restrictionsof single biometric systems and convenes the accuracyrequirements

Shekhar [14] investigated multiple palmprint recognitionusing rank level fusion which uses borda count bucklinhighest rank and logistic regressionMatch score level fusionusing feed forward neural network for the fusion of face andpalmprint has been investigated by Thepade and Bhondave[15] Yang et al [16] investigated multiple dependency ofpalmprint using feature level fusion and score level fusionWang and Han [9] investigated face iris fusion using scorelevel fusion Jain et al [17] investigated the multimodalbiometric system based on the face and hand geometrybiometrics at the score level
Conti et al [18] proposed a multimodal biometric basedon two-fingerprint acquisition which uses score level fusionand obtained an improvement of 6 when compared tomonomodal biometric based system Yang et al [19] usedmatched score level fusion to fuse hand geometry fingerprintand palmprint multimodal biometric system He used aself-constructed database of 97 subjects Besbes et al [20]proposed a hybrid multitrait biometric method using irisand fingerprint Yang et al [16] proposed decision levelfusion fingerprint templates Here assessment was taken byindividual unimodal assessment through an ldquoANDrdquo operator
Most significant contribution published in recent yearspertaining to multimodal biometric fusion focused exten-sively on fusing data at the matching score level and decisionlevel It has been observed thatmost of the important featuresare lost on performing data fusion at the latter stages (matchscore level and decision level) In spite of the abundanceof investigations related to multimodal biometrics relativelylittle work was done at feature level fusion since featurefusion has rich information content compared to fusionat the later stages Therefore the current exploration on amultimodal biometric fusion at the feature level is anticipatedto attain improved recognition accuracy compared to thefusion at the later stages

22 Hierarchical Multiresolution Local Binary Pattern Ojalaet al [22] introduced local binary pattern in 1996 The localbinary pattern is a gray scale invariant texture measureand is a helpful tool to model texture images It tags thepixels representation by using threshold of the pixels ofthe local neighbor around each pixel and considers theresult as binary numbers It is a combining approach todivergent statistical and structural forms of texture anal-ysis The major property of hierarchical multiresolutionLBP is its robustness to monotonic gray scale alterationscaused An added advantage of hierarchical multiresolutionLBP is its computational simplicity to analyze images in

To enhance the performance of LBP operator mul-tiresolution LBP features are used Multiresolution LBPfeatures consist of richer information than the single LBPoperator Conventionally LBP features with different scalesare obtained and concatenated into a lengthy feature Theobtained feature contains enormous information but it has adrawback of curse of dimensionality
Nonuniform pattern contains more useful informationsome of the processing steps are investigated by Raja andGong [23] and Liao et al [24] However the recognition

3 Proposed Multimodal Feature FusionBlock Diagram
The proposed methodology for investigating the multimodalmultifeature biometric systems is based on the combinationof palmprint and iris Feature fusion has the advantage ofexploiting rich information from each biometric Figure 5represents proposed feature fusion multimodal biometricsystem based on Gabor and hierarchical multiresolutionLBP extraction The feature vectors are extracted indepen-dently from the preprocessed images of palmprint and irisThese features are normalized to obtain a single vectorThe feature vectors of input images (test image) are thenevaluated with the templates of the database (train image)to produce the output Fusing more than one modalityimproves the recognition accuracy reduces False AcceptanceRate and False Rejection Rate The proposed multimodalmultifeature biometric method overcomes the restrictionsof single biometric systems and convenes the accuracyrequirements

real time Hierarchical multiresolution LBP is operated witheight neighbors of a pixel with the value of the middlepixel as a threshold Hierarchical multiresolution LBP codesfor a neighbor are produced by multiplying the thresholdassessment with weights specified to the resultant pixels andthe results are summated It is executed by an orthogonalmeasure of local contrast The averages of gray levels underthe middle pixel are deduced from that of the gray levels overthe center pixel Two-dimensional distributions hierarchicalmultiresolution LBP and local contrast measures are used asfeatures

To enhance the performance of LBP operator mul-tiresolution LBP features are used Multiresolution LBPfeatures consist of richer information than the single LBPoperator Conventionally LBP features with different scalesare obtained and concatenated into a lengthy feature Theobtained feature contains enormous information but it has adrawback of curse of dimensionality
Nonuniform pattern contains more useful informationsome of the processing steps are investigated by Raja andGong [23] and Liao et al [24] However the recognition

accuracy depends on the training samples Figure 3 explainsan illustration of the binary pattern It consists of nonuniform(bigger radius) and uniform (smaller radius) patterns Forthe uniform pattern a subhistogram is constructed but forthe nonuniform pattern they are processed to dig out theirLBP pattern by smaller dimension Thus the processingsteps are continued until the pixels patterns are uniformFigure 4 explains the proposed multiresolution hierarchicalLBP system Initially LBP histogram is constructed Usingnonuniform pattern for 119877 = 3 a new histogram patternof 119877 = 2 is constructed Then using nonuniform pattern119877 = 2 are processed to obtain the histogram pattern of119877 = 1
3 Proposed Multimodal Feature FusionBlock Diagram
The proposed methodology for investigating the multimodalmultifeature biometric systems is based on the combinationof palmprint and iris Feature fusion has the advantage ofexploiting rich information from each biometric Figure 5represents proposed feature fusion multimodal biometricsystem based on Gabor and hierarchical multiresolutionLBP extraction The feature vectors are extracted indepen-dently from the preprocessed images of palmprint and irisThese features are normalized to obtain a single vectorThe feature vectors of input images (test image) are thenevaluated with the templates of the database (train image)to produce the output Fusing more than one modalityimproves the recognition accuracy reduces False AcceptanceRate and False Rejection Rate The proposed multimodalmultifeature biometric method overcomes the restrictionsof single biometric systems and convenes the accuracyrequirements
