Translasi Bahasa Isyarat
No full textDue to their disability, hearing-impaired uses sign language as their primary means of communication. Sign language uses hand shape, facial expression, and body gesture. However this type of communication is unfamiliar to most people therefore communication between hearing-impaired and normal people can be difficult. There is a need for a system to translate sign language into spoken/written language, so that communication between hearing impaired and normal people can be simplified. To build this final project, the use of web camera is necessary to capture the image of the user�s hand. In general this program works by tracking the hand of the user, extract the shape of the hand, and then classify it. To track the position of the hand, we use HaarClassifier that has been trained prior to this project. To extract the hand we use skin detection and noise removal in which the resultan image will then be thresholded and normalized. After the image of the hand shape is extracted, the next step is to classify it by using k nearest neighbor algoritm. Each of the normalized binary images is then converted to feature vector, from this feature vector, distance is measured to find out the majority neighbor in which the new data belongs to. This system able to identify 19 fingerspelling signs out of 26 inteded signs to be identified. The average accuracy for this system is 89.68%. This value can vary depending on the data training consistency dan noise produced

Metode Pengurangan Sampling dan Penggunaan Banyak Frekuensi Sampling untuk Analisa Transformasi Fourier Digital pada Aplikasi yang Berbasis Mikrokontroler
No full textAnalisa Fourier adalah salah satu metode yang banyak digunakan untuk berbagai aplikasi. DFT dan FFT adalah model dan algoritma yang umumnya digunakan dalam sistem proses digital. Masalah yang sering muncul yang berkaitan dengan DFT atau FFT adalah waktu komputasi dan kapasitas memori. Jika perangkat pemroses yang digunakan adalah PC, hal ini tidak menjadi masalah. Namun tidak demikian jika menggunakan mikroprosesor atau mikrokontroler. Teknik yang digunakan di sini akan sangat mengurangi waktu komputasi dan kebutuhan memory yang akan sesuai untuk aplikasi yang berbasis mikrokontroler. Teknik yang digunakan adalah memecah spectrum frekuensi yang lebar dari sinyal masukan menjadi beberapa band yang lebih kecil dengan teknik menggunakan lebih dari satu frekuensi sampling. Dan mengurangi panjang sampling yang semula ratusan atau ribuan sampling menjadi hanya beberapa puluh sampling. Sebagai contoh hasil, pada pengujian kali ini digunakan pada aplikasi analisa spektrum sinyal audio dengan rentang 20 Hz sampai 20 kHz yang seharusnya menggunakan frekuensi sampling 40 kHz dengan panjang sampling 2000 sampling. Pada percobaan ini dapat dipecah dan dikurangi menjadi hanya 3 band masing-masing 20 sampling, total 60 samplin
