“…Hasil tersebut juga menunjukkan kinerja penggunaan filter median dan deteksi tepi canny. Penggunaan teknik tersebut mempermudah pembuatan algoritme deteksi tepi [14] dan mengurangi derau yang dapat mengurangi kesalahan proses pembacaan parameter dengan waktu pemrosesan yang singkat [13]. Nilai parameter 1 menjadi sebuah acuan untuk mendapatkan informasi tentang jarak garis pandu di depan robot.…”

Line following and lane tracking are robotic navigation techniques that use lines as a guide. The techniques can be applied to mobile robots in the industry. This research applied the Braitenberg controller and image processing to control and obtain line information around the mobile robot. The robot was implemented using Arduino Uno as a controller. A webcam was connected to a computer that performs image processing using canny edge detection and sends the data to the robot controller via serial communication. The robot can navigate on the side of the line, and the success rate of the system is 100 % at a turn of 135 ° and 80 % at a turn of 90 °.

Abstrak-Robot merupakan teknologi yang dapat membantu manusia dalam melakukan suatu kegiatan tertentu Salah satu jenis robot adalah robot lengan. Robot lengan dapat bekerja secara otomatis maupun manual, beberapa teknik yang dapat digunakan untuk memberikan perintah pada robot adalah menggunakan gestur tangan dan jari, untuk melakukan teknik tersebut dapat memanfaatkan mesin vision. Salah satu kelebihan menggunakan mesin vision adalah tidak memerlukan banyak komponen elektronika untuk mengenali gestur tangan atau gerakan jari. Fokus penelitian ini adalah mengimplementasikan kamera untuk mengenali gestur jari operator sehingga mampu memberikan perintah kepada robot. Kamera akan menangkap citra dari jari operator, citra tersebut akan diproses di dalam komputer untuk mendapatkan parameter koordinat piksel ujung jari telunjuk dan piksel bagian bawah kanan dari citra, dan kemudian akan ditentukan sudut yang diperoleh dari kedua koordinat tersebut. Hasil yang didapat adalah robot dapat mengikuti gerakan jari pada sudut antara 30° sampai 150°. Kata kunci: gestur, pengolahan citra, robot lenganAbstract-The Robot is a technology that can help human to do daily activities. One type of robot is an arm robot, arm robot can work automatically, manually, and a combination of both. Some techniques that can be used to give commands to the robot are to use hand and finger gestures, to do the techniques can utilize the vision machine. One of the advantages of using a vision machine is that it does not require many electronic components to recognize hand and finger gestures. The focus of this research is to implement a camera to recognize the operator's finger gestures so that the gesture can give commands to the robot. The camera captures the image of operator's finger, the image is a process inside the computer to obtain the pixel coordinate parameters of the index fingertip and right lower pixel of the image, and then the angle obtained from both coordinates using trigonometric equations. The result is that the robot can follow the movement of the finger when the angle between 30° to 150°.

In analysis of minutiae based fingerprint systems, fingerprints needs to be pre-processed. The preprocessing is carried out to enhance the quality of the fingerprint and to obtain more accurate minutiae points. Reducing the pre-processing time is important for identification and verification in real time systems and especially for databases holding large fingerprints information. Parallel processing and parallel CPU computing can be considered as distribution of processes over multi core processor. This is done by using parallel programming techniques. Reducing the execution time is the main objective in parallel processing. In this study, pre-processing of minutiae based fingerprint system is implemented by parallel processing on multi core computers using OpenMP and on graphics processor using CUDA to improve execution time. The execution times and speedup ratios are compared with the one that of single core processor. The results show that by using parallel processing, execution time is substantially improved. The improvement ratios obtained for different pre-processing algorithms allowed us to make suggestions on the more suitable approaches for parallelization.
