Metode alternatif dari metode pengukuran kecepatan kendaraan menggunakan alat berbasis laser atau radar dengan menggunakan citra. Sebuah citra memiliki blur pada objek yang bergerak (motion blur) dikarenakan efek yang disebabkan oleh gerakan relatif antara kamera dan objek yang bergerak. Hasil identifikasi ukuran blur dimanfaatkan sebagai salah satu parameter untuk estimasi kecepatan kendaraan. Proses identifikasi blur menggunakan 5 tahap yaitu melakukan Fourier transform terhadap citra yang telah melalui preprocessing, menghitung log spectrum, melakukan inverse Fourier transform, mengubah matriks 2 dimensi menjadi 1 dimensi dan menemukan nilai puncak negatif pertama sebagai koresponden panjang blur. Setelah ukuran blur teridentifikasi, selanjutnya dilakukan proses estimasi kecepatan kendaraan dengan menyertakan parameter lain yaitu shutter speed, focal length, CCD size dan jarak objek. Berdasarkan hasil pengujian, tingkat akurasi aplikasi estimasi kecepatan kendaraan menggunakan citra motion blur ini adalah sebesar 77.15%. Keakuratan aplikasi dapat dipengaruhi beberapa faktor yaitu posisi kendaraan pada citra, resolusi, shutter speed, jarak objek dengan kamera dan intensitas cahaya.

The development of HCI (Human Computer Interface) has grown more user-friendly. The traditional way of inputting data using keyboard has been replaced gradually since a lot of new method developed. Touch panel developed from single-touch to multi-touch. Body sense technology even removes obstacles in input device so HCI becomes closer to human nature movement. The most important thing from HCI is manipulating by using hand. The object of this research is to build an application which gives user ability to control pointer by using hand gesture. Method which is used in the application to recognize hand gesture is Convex Hull Algorithm. Convex Hull Algorithm is a method which is used to detect contour or object in image by using points which are connected by lines that cover the contour. The result of this research shows that the application could give the user ability to control the pointer by using hand gesture. Nevertheless, the overall object detections are still needs to be improved because they are easily distracted by background or object having the same colors as the user’s hand.

Kompresi data adalah proses mengubah suatu input data menjadi data dengan ukuran yang lebih kecil, atau proses pengkodean dari suatu data untuk mengurangi kebutuhan akan media penyimpanan. Kompresi data bertujuan untuk mengurangi ukuran data tanpa merusak tujuan dari data tersebut.Kompresi data menggunakan sedikit disk space. Kompresi data mempercepat akses, kompresi data dapat membuat lebih efisien. Algoritma yang digunakan dalam penelitian ini adalah Arithmetic Coding. Algoritma Arithmetic Coding adalah suatu bagian dari entropy encoding yang mengkonversi suatu data ke dalam bentuk data yang lain dengan lebih sering menggunakan sedikit bit dan jarang menggunakan lebih banyak bit karakter. Teknik pengkodean ini memisahkan pesan masukan ke dalam simbol dan menukar masing–masing simbol dengan suatu floating-point. Hasil dari penelitian ini yaitu kompresi menggunakan algoritma Arithmetic Coding dapat menghasilkan citra dengan ukuran file yang lebih kecil, namun apabila citra uji yang digunakan mempunyai ukuran file yang besar, waktu yang dibutuhkan untuk melakukan proses kompresi maupun dekompresi membutuhkan waktu yang cukup lama. Dari hasil pengamatan, tingkat rasio kompresi tidak dipengaruhi oleh besarnya ukuran dimensi citra, tetapi tergantung komposisi warna citra yang bersangkutan. File citra hasil kompresi tidak dapat dibuka sebelum melewati proses dekompresi hal tersebut disebabkan terjadi perubahan struktur pada file citra saat proses dekompresi. Kata kunci : Citra, Arithmetic Coding, Kompresi, Dekompresi dan Lossles
