Cara aman untuk mengenali seseorang adalah dengan teknologi biometrik. Telapak tangan merupakan biometrika yang masih relatif baru bila dibandingkan dengan sistem biometrika seperti wajah maupun sidik jari. Ciri yang digunakan adalah garis utama telapak tangan. Untuk mengekstraksi ciri, digunakan metode Principal Component Analysis (PCA) dan Overlapping Block, dengan metode pengenalannya menggunakan ukuran kemiripan jarak Euclidean. Pengujian dilakukan terhadap 30 individu. Berdasarkan hasil pengujian menggunakan metode PCA dengan variasi jumlah 50,75, dan 100 komponen utama dihasilkan tingkat pengenalan yang sama yaitu 90%. Sedangkan pengujian menggunakan citra dengan intensitas pencahayaan yang kurang, dihasilkan penurunan pengenalan menjadi 80%. Namun, untuk pengujian menggunakan 10 responden uji di luar 30 responden latih dan uji yang terdaftar dalam basisdata tidak ada yang dikenali. Sementara itu, dengan metode overlapping block, dari hasil pengujian dapat disimpulkan bahwa sistem identifikasi garis-garis telapak tangan memiliki tingkat keberhasilan pengenalan 100%, baik dengan menggunakan citra uji telapak tangan yang telah dilatih maupun dengan citra uji luar. Sistem hanya mampu memberikan tingkat keberhasilan 30% apabila intensitas cahaya ruangan dikurangi dan tingkat pengenalan 40% untuk perubahan jarak antara telapak tangan dengan kamera.Â

Iris is a part of the circle around the eye pupil. Iris has a very unique pattern, different in each individual. On this basis the iris can be used as the basis for the introduction of biometrics. To identify the texture of the iris in an eye image, method of texture analysis can be used. There are several methods of texture analysis, one of which is to use a wavelet based on image feature extraction energy. The analysis uses the energy characteristics contained in wavelet transform. Based on that reason, in this research an application program to identify the iris of the eye based on Daubechies order 4 wavelet transform. Â Eye image used in this research was acquired and processed, beginning take on the characteristics and texture of the iris image which converted into polar form. Then the feature extraction is done using Daubechies wavelet transform order 4. The characteristics obtained is in the form of the energy value. The next stage is the recognitionÂ using nearest normalized Euclidean distance. Tests carried out in the research consist of four types: influence of sample database, influence of the decomposition level of Daubechies wavelet transform order 4, influence of different input image formats, and testing on eye images which are not in database. From the test results, it can be concluded that the highest recognition rate with the parameters shown in testing Daubechies wavelet transform order 4 level 4 with two samples iris image stored is 86.66%. The lowest recognition rate is shown in tests with Daubechies wavelet transform order 4 level 6 with one sample iris image stored is 62.5%. Then from the results of testing the influence of different input image formats, it can be concluded that the samples taken from 40 individuals which one sample is take for each person, use the format BMP asÂ well as with use JPEG format. Whereas, from the test result for eye images which are not in database with threshold 0.3559, of the recognition level is 96%.Â Keyword :Â Â texture analysis, Daubechies wavelet transform order 4, iris, Euclidean distance

During this time, computer cursor operation was done by pressing and moving the mouse. So, this is less flexible for computer user that require movement in operating a computer, since to use mouse comfortably someone has to sit. Moreover, physical completeness is required for mouse operating, so that for someone who has physical disabilities feels difficult to operate it. Therefore, it is required to develop a system that provides a better comfort and flexibility not only for the healthy user computer but also for the user computer who has physical disabilities. In this final project, computer cursor operation program via voice is created. With this program, someone will have more flexibility when operating the computer cursor and also people with physical disabilities is enabled to communicate with computer. Voice recognition is a technology that is apllied in this program, with the feature extraction process used MFCC (Mel-Frequency Cepstrum Coefficients) method. As for the recognitions process used artificial neural network type LVQ (Learning Vector Quantization). Voice is passed through a microphone and then it is analyzed by MFCC to produce MFCC coefficients. These coefficients are used as input vector for LVQ neural network and used as data to train the network until it has the classification capability. Programming language that is used in creating this software is Delphi programming language. Based on the result of the testing program, it is found that the success percentage rate of voice recognition with training data, that is data which is derived from databases that have been recorded and trained into the program which amounts to 240 data, is 88,89 %. While in the testing with test data, that is data which is derived from the real time sayings of respondents which is amounts to 240 data, it is found that the success percentage rate of voice recognition is 83,99 %.

The development of image processing technologies now provide the possibility of human to create a system that can recognize a digital image. One method to recognize a digital image is the template matching. This method serves to find small parts of the image that matches the template image. Among the technologies to solve the problem of image processing is a system of classifying fingerprints into the form of software that is able to process the fingerprint image enhancement and match fingerprint images that have been recorded by the database system and classify fingerprints into a particular class. In this final project made â€‹â€‹an application that aims to classify the fingerprint image into a particular class using template matching method.Classification process is started with fingerprint image acquisition, images size distorting 256x256, grayscale(gray level), histeq (histogram equalization), binary (image distorting becomes two scales black and white), thinning, image gets to aim, and resize 32x32. The process will then be calculated percentage of similarity with the template fingerprint image file by using the calculation of NC (Normalized Cross Correlation). The biggest percentage value indicates that the template matches the fingerprint image files. The experiment has been done classification process as much as 61 input fingerprint image with each 5 image formats are *.bmp, *.gif, *.jpg, *.png, and *.tif, so the total input fingerprint image as much as 305. For image format type *.bmp, *. gif, *. png, and *.tif on type template Plain Arch, Plain Whorl, and Double Loop point out that its success zoom as big as 100%.
