Abstract
INDONESIA:
Tulan mandibula adalah tulang rahang pembentuk wajah. Mandibula terletak pada tulang rahang bagian bawah. Tulang mandibula dapat digunakan dalam pendeteksian osteoporosis. Salah satu cara yang dapat dilakukan yaitu dengan mengukur lebar sisi tulang mandibula tersebut. Untuk itu diperlukan perbaikan citra tulang mandibula agar memperjelas batas-batas tulang mandibula tersebut. Penelitian ini membahas perbaikan kualitas citra dental panoramic radiograph khususnya pada tulang mandibula dengan menggunakan impulsive noise removal. Tujuannya adalah untuk membuktikan impulsive noise removal mampu memperbaiki kualitas citra tulang mandibula pada dental panoramic radiograph dan mengukur performa impulsive noise removal dalam memperbaiki kualitas citra tulang mandibula pada dental panoramic radiograph. Tahap proses pada aplikasi ini yaitu pre-processing (cropping dan grayscale), Main- processing (impulsive noise dengan penghitungan kontras citra dan penghapusan noise dengan rata-rata nilai batas citra yang normal antara 23 hingga 33, jika lebih dari nilai tersebut maka citra tersebut mengandung noise), serta Post-processing (segmentasi menggunakan transformasi watershed). Uji coba dilakukan dengan menggunakan 50 citra ujicoba. Hasil uji coba tersebut diketahui keakuratan citranya yaitu dengan menghitung nilai accuracy, precision, dan recallnya. Keberhasilan aplikasi ini dalam memperbaiki kualitas citra tulang mandibula pada dental panoramic radiograph ditunjukkan dengan nilai accuracy citra setelah diberi perlakuan impulsive noise removal adalah sebesar 72,8%, precision 75,5%, serta recall 65,14%. Sedangkan accuracy sebelum diberi perlakuan impulsive noise removal adalah 60,86%, precision 70,24%, serta recall 63,43%.
ENGLISH:
The bones of the mandible is the jaw bone forming the face. The mandible is the jaw bone on the bottom. The mandibular bone can be used in the detection of osteoporosis. One way to do that is by measuring the width of the side of the mandible bone. It was necessary to repair the image of the mandibular bone in order to clarify the boundaries of the mandibular bone. This study discusses the improvement of image quality especially in dental panoramic radiograph of mandibular bone by using impulsive noise removal. The goal is to prove impulsive noise removal can improve the image quality of the mandibular bone in dental panoramic radiographs and measuring the performance of impulsive noise removal in improving the image quality of the mandibular bone in dental panoramic radiographs. This application process at the stage of pre-processing (cropping and grayscale), Main-processing (impulsive noise by calculating the contrast of the image and noise elimination with median values of a normal image boundaries between 23 and 33, if more than the value of the image contains noise), as well as Post-processing (segmentation using watershed transformation). The test is done by using 50 test images. The trial results known to the accuracy of the image that is by calculating the values of accuracy, precision, and recallnya. The success of this application in repairing mandibular bone image quality in dental panoramic radiograph shown with accuracy the image after being given treatment of impulsive noise removal is of 72,8%, precision landslide 75.5%, and 65,14% recall. As for accuracy before being given treatment of impulsive noise removal is 60,86%, 70,24%, precision and recall 63,43%.
