Abstract

Abstract Computer vision is an image processing by a computer to obtain information from image captured through the camera generally used in real-time application. This paper reports on the results of research conducted on computer vision system designed to be able to recognize the image number (0-9) and mathematical operators (addition (+) and subtraction (-)) in a card number figures. Computer vision system designed in this study consists of a camera on the android phone that used to captured images on the card number and the computer that has artificial neural network perceptron algorithm in identifiying images. Both components of the computer vision system are connected wirelessly through the TCP/IP Protocol. At the training stage of Perceptron ANN, 10 samples for each number and mathematical operators are used. Computer vision system built in this study also have several image processing techniques such as greyscalling, thresholding, cropping and resizing. This techniques is used to filter the information from the images captured by camera in order to get the adequate and smaller image to be processed by ANN Perceptron. Stages of testing performed three times. First testing is given picture numbers 0-3, second testing is given picture number 4-7 and third testing is given number 8-9, addition symbol and subtraction symbol. Based on testing result, system built are able to recognize 10 from 12 image rendered with a success rate of 83.33%.Keywords : Computer vision, perceptron, card number Abstrak Computer vision merupakan proses pengolahan citra oleh computer untuk mendapatkan informasi dari citra yang ditangkap melalui kamera yang umumnya digunakan pada aplikasi waktu nyata. Tulisan ini melaporkan tentang hasil penelitian yang dilakukan tentang sistem computer vision yang dirancang untuk dapat mengenali gambar angka (0-9) dan operator matematika(penjumlahan (+) dan pengurangan (-)) pada permainan kartu angka. Sistem computer vision yang dirancang pada penelitian ini terdiri dari kamera pada ponsel android yang digunakan untuk menangkap gambar pada kartu angka dan komputer yang memiliki algoritama Jaringan Syaraf Tiruan Perceptron dalam melakukan identifikasi gambar. Kedua komponen sistem computer vision tersebut dihubungkan memlaui jaringan wireless melalui protocol TCP/IP.

Abstract

Electricity meter is a tool used to measure the electricity power consumption. Electricity meter has the numeral part known as electricity meter number which load the electricity power consumption.Usually, the recording is done once a month, by recording the number on the electric meter into the book, and then the recording officer take pictures the power meter. Electricity meter number can be analized through an image using the knowledge of pattern recognition in image processing. In analyzing picture of electicity meter number, we used Histogram Of Oriented Gradients (HOG) as the feature extraction and Supply Vector Machine (SVM) as the classification method. The result using 100 train-set and 30 test-set for each combination of category shows that the best resolution is 10 MP and 14 MP and the picture capturing distance is at 30 cm byand 10 cm by 73,33%  accuracy for each image and 86,67% for each number and confusion matrix shows that presentation of all number is 75,48%. Key words:Number Recognition, Histogram Of Oriented Gradients (HOG) , Support Vector Machine (SVM)

Abstract

AbstractWatermarking videos are useful to determine authentication rights to a video. The step of watermarking is by inserting binary images on an MPEG1 format video using discrete wavelet transformations, and extracting watermark videos. Analysis of video watermark quality can be known by calculatong PSNR. Video watermark quality analysis is done after carrying out the watermarking and extraction process to find out the difference the original video quality and the video watermark and the insertion image used. The results of video watermark quality analysis showed that 100% video watermarks did not change from the original video and binary imagery was better than the color image in the insert image.Keyword : video watermarking, authentication, binary imagery, insert image, discrete wavelet transformation, PSNR.AbstrakWatermarking video berguna untuk menentukan hak otentikasi terhadap suatu video. Tahapan watermarking adalah penyisipan citra biner terhadap suatu video berformat MPEG1 menggunakan transformasi wavelet diskrit, dan melakukan ekstraksi terhadap video watermark. Analisis kualitas video watermark dapat diketahui dengan perhitungan PSNR. Analisis kualitas video watermark dilakukan setelah melakukan proses watermarking dan ekstraksi untuk mengetahui apakah perbedaan  kualitas video asli dengan video watermark dan citra sisipan yang digunakan. Hasil analisis kualitas video watermark menunjukkan bahwa 100% video watermark tidak mengalami perubahan dari video asli dan citra biner lebih baik daripada citra berwarna pada citra sisipan.Kata kunci : watermarkingi video, otentikasi, citra biner, citra sisipan, transformasi wavelet diskrit, PSNR.

Abstract

The development of telecommunications technology in the era of globalization happens very rapidly to help people to communication and one of the communication technology is using telephone device. However, the absence of security in securing data/information of delivery Short Message Service (SMS) that is confidential causes the message easily stolen by unauthorized parties. SMS sent via the BTS will be accepted Message Service Center (SMSC) been causing a crack misuse of the information. One way to secure the data from the data communication process is by cryptography. This research using descriptive statistical research methods. This research was conducted by analyzing the security by implementing the RC6 algorithm in cryptography and compression applications based on android SMS. The RC6 algorithm is an symmetric cryptographic algorithm that use the same key in encryption and decryption of SMS message. The encryption process that changes the number bits of data affects the number of SMSs that need to be sent, so text compression is required. The Huffman algorithm is a lossless data compression algorithm in which data compression does not eliminate one byte and is stored as originally. So the result of decompress is same with original ciphertext. Testing is done using Blackbox Method.This research was conducted to solve the security problem of sending SMS with cryptography and send data can be compressed to save SMS cost.Keywords : Cryptography, Encryption, Decryption, SMS, Mobile, RC6, Huffman,android
